Bam's Hell Train Team
Boro
Boro
Tower Position: Fisherman
Once I can read a weapon's movement, wielding it against me is futile... You've picked the wrong opponent, swordsman.
A D-rank Regular who had previously been on the Hell Train, and now serves as a Shinsu martial arts teacher for Hanool and Felix. Boro agrees to become part of Bam's new Hell Train team after getting word that a group led by Rachel is planning to slaughter everyone who will board the train.
Following the Hell Train's Dallar Show, Boro is one of the Regulars that joins Bam's group to journey to the forbidden 43rd Floor.
- Awesomeness by Analysis: He is skilled in analyzing the properties of a weapon, and thus easily takes down Hong Danhwa, who is wielding a powerful Ignition Weapon sword.
- Badass Teacher: Towards his two Shinsu students. His introduction shows off his abilities as he kills off a ticket hunter, and later takes down a member of the Hong family without breaking a sweat.
- Curb-Stomp Battle: Performs one on a ticket hunter; killing him outright.
- Curtains Match the Window: Gray hair with gray eyes.
- Dark and Troubled Past: His last attempt on the Hell Train ended up with everyone on board, apart from his teammates Aka, Daniel, Sachi Faker and Roen being killed by a FUG Slayer candidate. Roen ended up being killed too.
- Goal in Life: Similar to the rest of his old team, Boro stayed connected to the Hell Train in order to find out what happened to Roen. After finding out that Roen can't return, he has a new goal to stop Hoaqin at the 43rd Floor of Death.
- Number Two: To Bam for their Hell Train team.
- Out of Focus: Compared to the amount of time spent hyping up the character before entering the Hell Train, he hasn't gotten to do much since.
- Really 700 Years Old: He has been on the Hell Train twice and his first attempt on the train was 600 years ago.
- Red Oni, Blue Oni: The red to Sachi's blue.
- Scars Are Forever: A scar on his left cheek.
- Student–Master Team: The master to his two students, Hanool and Felix.
- Those Two Guys: Becomes this with Sachi ever since the two reunited in the present.
Hanool Kang
Hanool Kang
I've felt something ever since I got here. The Hell Train is too dangerous for someone like me.
A D-rank Regular, and one of Boro's two Shinsu students alongside Felix. He becomes part of Bam's Hell Train team after Boro accepts his alliance offer.
After participating in the Hell Train's Dallar Show, Hanool decides to not join Bam's 43rd Floor expedition team in order to look after those that were injured in said Dallar Show.
- The Big Guy: The biggest of Boro and Bam's group; even after Rak's return who the latter still prefers to walk around in his small form.
- Butt-Monkey: Established as one for Bam's Hell Train team to the point that even his teacher looks down on him to a certain degree.
- In-Series Nickname: Doesn't help that Bam has decided to dub him "Mr. Fatty."
- Epic Fail: His attempt to fight Regulars on his own by order of Boro... did not go so well.
- Hidden Badass: Has shades of awesomeness such as going on a suicidal run with the Crazy Ball in the first Hell Train match.
- Hidden Depths: His medical knowledge has made him the team doctor for Bam's Hell Train group.
- The Medic: Has some knowledge of being a doctor, such as when he bandaged up Hana's injured hands after the Crazy Ball match. Hanool was also usually seen as the one looking after people's injuries that people on Bam's team obtained during the Dallar Show.
- Power of Trust: Continues to follow along with Bam's selfishness in the "Crazy Ball" match in order to win against Ha Yura.
- Put on a Bus: Hanool doesn't join Bam's expedition team to the 43rd Floor in order to look after the injured Aka and Daniel.
- Satellite Character: Similar to Felix, they hardly have any character depth aside from their connection through Boro.
- Student–Master Team: The student to his master, Boro.
Hana Yu
Hana Yu
Tower Position: Light Bearer
My dream is to become an idol singer... I have always dreamed of becoming someone famous. That's why I came into the Tower.
A D-rank, Light Bearer, Regular who dreams to follow in Ha Yura's footsteps to become an idol singer. Introduced working as a train crewmen, she gets caught up in a scuffle over Hell Train tickets, and winds up as one of Bam's teammates to board the Hell Train.
Hana is forced out of the team after suffering an injury in the 35th Floor's Train City tournament.
- Butt-Monkey: Not at the same level as Hanool, but still not taken that seriously.
- Everything's Better with Sparkles: Sparkle effect when she's excited about something.
- Fangirl: Towards the idol singer, Ha Yura.
- Game-Breaking Injury: Injures her hands after taking the full power of the Crazy Ball from Ha Yura.
- Idol Singer: What Hana hopes to be in the future.
- In-Series Nickname: Being called "Train Crew" due to her previous work as train crewmen.
- Put on a Bus: After suffering a severe injury, she has to give up her Express Ticket to Hong Danhwa.
- This Is Unforgivable!: Hana Yu takes it hard that Ha Yura treats her near-fatal attack on her like it was nothing.
Aka's Hell Train Team
Aka Williams
Aka Williams
Tower Position: Defender
Maybe we could have found a way...to beat Hoaqin without getting anyone killed.... We all told her not to do it, but deep down inside...perhaps we were glad that Roen chose to sacrifice herself. Since we were so terrified of death.
A D-rank Regular who was part of Boro's previous Hell Train team, and is now leading one of the teams trying to board the Hell Train in the present. He also has the rare Defender Position, which is usually to protect the Light-Bearer and Spear-Bearer Regulars at the back of the fight.
His group later joins forces with Bam after finding out about Rachel's plan. However, his injuries during the Dallar show forces him to end his current Hell Train journey.
- The Big Guy: Largest among the Hell Train Regulars.
- Dark and Troubled Past: He was part of Boro's group in the past when their team encountered a FUG Slayer candidate that massacred everyone on board the train. The two went their separate ways after that.
- Dude Looks Like a Lady: Oh dear god, yes. And the lips and outfit sure don't help. In fact, Beta regularly refers to him as a she, much to his annoyance. Unlike most examples, though, Aka is anything but pretty; he looks like a burly, middle-aged female bodybuilder in a schoolgirl uniform, wearing a bit too much makeup.
- Greed: Boro describes him to be a very greedy person.
- Goal in Life: Similar to the rest of his old team, Aka stayed connected to the Hell Train in order to find out what happened to Roen. After finding out that Roen can't return, he ends his Hell Train journey due to the injuries he obtained in the Dallar Show.
- The Leader: Of one of the Hell Train teams.
- Playing with Fire: His abilities take on a fire element.
- Put on a Bus: Due to the injuries he received in the Dallar Show, Aka isn't able to continue with Bam's expedition group to the forbidden 43rd Floor.
- Putting the Band Back Together: Aka goes looking for his old Hell Train teammate, Sachi, after learning about Daniel's objective to revive Roen using Hoaqin's power. The two reunite with Boro at the next Hell Train pit-stop.
- Really 700 Years Old: Considering he was there with Boro 600 years ago, this is a given.
Moontari
Moontari
The choice for Hell Train newbies…is join Sir Aka or die.
A D-rank Regular that acts as Aka's second-in-command.
- Amazing Technicolor Population: Blue-skinned.
- Character Death: Gets disposed of brutally in the Dallar Show, courtesy of Buelsar Elliot.
- Number Two: To Aka.
- Out of Focus: Despite some minor build-up during Revolution Road, his character was quickly pushed to the background until the Dallar Show.
- The Rival: Seemed to be developing as one for Khun Ran. It didn't last.
- Undying Loyalty: To Aka.
- We Hardly Knew Ye: Apart form his loyalty to Aka, Moontari didn't have much else going for him.
- The Worf Effect: By using reverse-flow control, he took Khun Ran's attack without breaking a sweat when the latter came looking to pick a fight. He also makes a quick mention that he's fought, and killed, other members of the Khun Family. In the end though, none of the build-up mattered since Buelsar killed him off easily in the Dallar Show.
Team Aka's Three Other Members
Mahan, Blonde Gunner, Bald Light Bearer
Tower Position: Light Bearer (Bald Man), Unknown (Mahan and Blonde Gunner)
Mahan (left), Unnamed Teammates (middle and right)
The three other D-rank Regulars of Team Aka.
- Barrier Warrior: The bald Light Bearer can make Lighthouse barriers, which he uses a lighthouse field to shield Boro and Aka from being melted to Anna's juice jar.
- Big Damn Heroes: The gunner girl and bald Light Bearer arrive in time during the Dallar Show's pipe maze game to save Aka and Boro from being melted to Anna's large juice jar.
- Cool Shades: The bald Light Bearer is always seen wearing black eyeglasses.
- Curtains Match the Window: Yellow-hair and yellow-eyes for the blonde gunner girl.
- Flat Character: None of them were given any real character moments or focus. They're there just to fill out the remaining spots for Aka's 5-man Hell Train team.
- Girlish Pigtails: The blonde gunner girl of Team Aka has this hair-style.
- Long-Range Fighter: The gunner girl is usually seen wielding a rifle, which it can be assumed that she's the ranged sniper of the team.
- Menacing Mask: The blonde gunner girl wears a menacing looking black mask that covers her mouth.
- Mission Control: The bald guy of Team Aka is their Light Bearer, which it can be assumed that he's the one who communicates to the team through his Lighthouse.
- No Name Given: The blonde haired gunner girl and the bald-headed Light Bearer went unnamed.
- Scars Are Forever: The bald Light Bearer has a scar on his head.
- Small Role, Big Impact: The gunner girl and bald Light Bearer's biggest contribution was saving Aka and Boro during the Dallar Show from being melted to Anna's juice jar.
- Smurfette Principle: The gunner girl is the only woman of Aka's Hell Train team.
- Undying Loyalty: Similar to Moontari, they serve Aka loyally. Even coming to Aka's rescue during the Dallar Show.
- What Happened to the Mouse?: Mahan disappears after the Train City chapters. Unlike the blonde gunner and bald light bearer, Mahan isn't seen with Aka when they arrive at the Wooden Horse station to board the Hell Train.
Rachel's New Recruits
Daniel Hatchid
Daniel Hatchid
Tower Position: Scout
This world, without her, is meaningless. That's why I'm going to start over by changing this tedious, disgusting place.
A D-Rank Regular, and one of three newcomers of Rachel's team. As it turns out, he was part of Boro and Aka's previous Hell Train team when things fell apart for them. During the recent journey on the Hell Train he makes deals with both Rachel and Bam's sides in an attempt to resurrect a dead girl that he fell in love with.
Following the Hell Train's Dallar Show, Daniel ends his current Hell Train run due to his injuries, and rejoins Aka.
- Badass Adorable: Defeated 99 Regulars on his own during his search for Hell Train tickets. He also stood strong against the Hell Train guardian, and can fight on par with Bam.
- Character Tics: Is always seen biting on what looks to be a stick. Him biting on the stick seems to be an indication of when he's lying.
- Deal with the Devil: Knows full-well how dangerous Hoaqin is, but unseals him anyway under the promise to revive Roen.
- Determinator: He goes through quite a lot in an attempt to revive Roen. Though he finally lets it go upon realizing that Roen's soul makes up one of the many that created the final Hoaqin clone.
- Dragon with an Agenda: Although he's helping Hoaqin, he knows that Hoaqin will be harder to control if he reunites with his other half, which is why he wants to find the other one as late as possible. Justified, since it would be unwise to trust the one who killed his previous team. He becomes even more blatant about this when he offers to help Vicente find his other siblings in exchange for Roen's revival.
- Fangs Are Evil: Self-explanatory.
- Goal in Life: He wishes to resurrect Roen by using Hoaqin. After finding out that Roen can't return, he ends his Hell Train journey due to the injuries he obtained in the Dallar Show.
- In the Hood: The second to reveal his face to the readers. All three of the newcomers were hidden at first.
- Love Confession: Daniel asks the female Hoaqin clone housing a billion souls to pass on a message to Roen's soul that he loved her.
- Mysterious Past: His introduction implies that he has had past experience on the Hell Train. That past experience being that he was part of Boro and Aka's previous Hell Train team when a FUG Slayer candidate massacred everyone on the train.
- Necromantic: He believes if he gets on the Hell Train, he can find a way to bring his teammate, Roen, back to life.
- Not Quite Dead: It was believed, by Boro and Aka, that he had died on a return trip to the Hell Train more than 200 years ago. Daniel even confirms this himself (although whether he was lying is debatable).
- Outgambitted: His plan to backstab Hoaqin fails when it turns out the fusion spell only allows Hoaqin to be in control and not his siblings.
- Playing Both Sides: He's making a deal with Vicente in case Bam defeats Hoaqin.
- Put on a Bus: Due to the injury he received in the Dallar Show, Daniel isn't able to continue with Bam's expedition group to the forbidden 43rd Floor.
- Really 700 Years Old: He was part of Boro and Aka's Hell Train team 600 years ago.
- Soul Power: His special Shinsu control ability is one that utilises the 'living soul' and is a "living creature" that moves. As such the Shinsu can move as if it were alive and can seemingly move independently of Daniel's actions. Certain attacks are even worth a specific amount of people. May tie in to his seeming resurrection.
- Worthy Opponent: Considers the current group of Hell Train Regulars (such as Khun Ran's team) a decent batch of contenders.
Raguel
Raguel
Tower Position: Scout, Anima
So many idiots praise the Ten Great Families and choose to follow them. Ah — how pathetic. People like you make me sick. Dogs who accept that false power. I just wanna kill you all.
A D-rank Regular, and one of three newcomers of Rachel's team. Raguel is an illegitimate child of a member of one of the ten Families, which she has a deep hatred for due to her troubled past.
- The Beastmaster: She can summon giant "Metalfish" to devour her enemies.
- Character Tics: She has a tendency to lick her lips when she's excited.
- Dark and Troubled Past: Raguel's mother was seduced by a member of the 10 Families and came to believe that she was in love with him — to the point of obsession. But, her lover ended up abandoning her later, despite getting her pregnant with Raguel. After being born, Raguel would spend her early life dealing with Parental Neglect as her mother self-destructively tried throwing herself at powerful men trying to snag another Family lover, and blaming her little girl for any failure. In the end, her mother sold Raguel off to people who could see the potential with Shinsu manipulation that Raguel had within her. For enough money to live well on for a while.
- Flight: Can fly.
- I'm a Humanitarian: Eats other people that she gets sick of dealing with.
- In-Series Nickname: Her teammates call her Angel.
- In the Hood: The first to reveal her face to the readers. All three of the newcomers were hidden at first.
- Holy Halo: Has an angelic halo.
- Our Angels Are Different: Has all the details that makes her look like a heavenly angel at first glance... that is not the case ''at all''.
- Sadist: She takes pleasure in watching others suffer. Add in her cannibalism gimmick, and you get the feeling that this woman is absolutely nuts.
- The Smurfette Principle: The female of Rachel's three new team members.
- Weaponized Offspring: The Metalfish can create/split a plethora of
mini-Metalfish to overwhelm her enemies. - Winged Humanoid: She has angel-like wings.
- Your Terrorists Are Our Freedom Fighters: Like Ha Jinsung and Reflejo, she considers FUG's campaign against the 10 Families to be justified, due to the latter abusing their powers.
Buelsar Elliot
Buelsar Elliot
Tower Position: Fisherman
Let me introduce myself. I'm Buelsar Elliot, one of Slayer Yama's Mad Dogs. Following his order, I have come to side with Hoaqin in order to test you, and find out if you are worthy to become a Slayer Candidate.
A D-rank Regular, and one of three newcomers to Rachel's team. Like Baragav, he is one of Baylord Yama's three Mad Dog minions, and enjoys fighting with strong opponents.
- Blood Knight: Clearly enjoys partaking in thrilling battles and commended Viole for giving him one.
- Death Seeker: Seems to be at peace with dying, but only to those who can give him a good fight.
- In-Series Nickname: Similar to Baragav, he is also called "Mad Dog."
- In the Hood: He is the last to reveal his face. All three of the newcomers were hidden at first.
- Mysterious Past: Has a past with Baragav (the "Mad Dog" that was introduced in the Workshop chapters).
- Noble Demon: Shows Viole quite a bit of respect considering that Viole left FUG, and even goes out of his way to tell him Haoqin's true identity once he is defeated.
- The Quiet One: Compared to the other two new members, he doesn't talk much. His skirmish against Bam was the first time he was actually talking normally.
- Shout-Out: His special ability, "Hell in a Cell", is a blatant shout out to the famous WWF/WWE hell-in-a-cell matches.
- We Will Meet Again: Disappointed that he had to cut his fight with Bam short in order to get on the Hell Train with the rest of Rachel's team. He calls out to Bam wishing for another fight aboard the train.
- Worf Effect: Shows multiple times why he's easily much stronger than most D-rank Regulars, including his brutalisation of Moontari (a powerful and experienced Regular in his own right), only to be later curb-stomped by the partially "Revolutionised" Viole.
- Worthy Opponent: Knowing that Bam is FUG's Jyu Viole Grace, he considers Bam one.
Arie Siblings
Hoaqin
Hoaqin
My name is Hoaqin. I am the one who seeks to regain his throne. And with the assistance of FUG, I will have the Tower under my control. Soon, you will come to know... how great I truly am.
The first of five siblings that have been sealed aboard the Hell Train.
In the past, Hoaqin had made a deal with a Devil to obtain a forbidden spell that would allow for him to one day finally surpass his Great Family father, Arie Hon. Afterward, Hoaqin was the infamous Slayer candidate that massacred a bunch of Regulars on his first trip on the Hell Train in an attempt to regain his strength.
In the present, Hoaqin's sealed room is located by Daniel, who has also arrived with Team Rachel. Afterward, Hoaqin teams up with Rachel's group to face off against Jyu Viole Grace in the Slayer Candidate game in order to unite his siblings into becoming one again.
Following the Hell Train's Dallar Show, Hoaqin's one of the few remaining teammates in Rachel's group as they make their way to the forbidden 43rd Floor.
- All There in the Manual: Quite a lot of his backstory as White was initially written out in one of SIU's setting blog posts, so this led to a lot of I Knew It! moments for the fans who paid attention to those once The Reveal came up.
- Ambition Is Evil: All Hoaqin (and his siblings) really wanted was to be acknowledged by their father. To that end, Hoaqin dabbled in ancient magic, was the one that suggested fusing with his siblings to increase their power and, after taking the driver's seat of their fused form, he climbed the Tower and became a Ranker and an infamous Slayer of FUG. He even declares to Vicente that everything that White had achieved up until this point was down to ''his'' accomplishments.
- Arc Villain: Hoaqin fights against Viole's team during the Hell Train's Dallar Show between the two Slayer Candidates. After losing the Dallar Show, he reluctantly became part of Rachel's group.
- Bad Boss: He's willing to endanger Cassano just for the sake of delivering a Hope Spot to Wangnan's group For the Evulz. Of course, he didn't tell Cassano about it because he wanted the charade to be as convincing as possible. Naturally, Cassano isn't amused at being Locked Out of the Loop.
- BFS: A long claymore that comes with a spiked cross-guard. Looks particularly big considering his own size.
- Break the Haughty: Hoaqin's subplot during the Floor of Death ends with him as powerful as ever once stealing the souls of the Floor's residents, but unable to leave due to the curse placed upon them affecting him as well. Gustang taunting him for his inability to see the bigger picture (and that he'll never earn Inetia's respect), along with casually taking all the souls back from him, sends him into a depression.
- Cool Crown: Wears a small white crown.
- Curtains Match the Window: Silver hair with silver eyes.
- The Dark Arts: Long ago, Hoaqin came across a forbidden spell left behind by an ancient devil called the "Spell of soul-eating", a spell that allows many to become one by eating each other's souls, and then used it alongside his siblings to become White. After doing so, he continued his interest in sorcery, rituals and dangerous magic.
- Deal with the Devil: Hoaqin made one with an ancient demon that came to him in his sleep. By offering up his siblings to the demon, he would receive great power. This came in the form of a fusion spell that assured he would always be in the driver's seat of the fused form.
- The Dreaded: Ha Jinsung's condition for allowing Bam to face Hoaqin is to defeat the former first, implying Hoaqin is a High Ranker level threat. Turns out he is.
- Dude Looks Like a Lady: He is very androgynous to say the least. Hoaqin's appearance is such that people are still calling doubt to "his" gender due to gender neutrality being Lost in Translation. It doesn't help that among his siblings whom he wants to absorb, there's at least one sister who also resembles him so much.
- Enemy Mine: He doesn't like the idea of Rachel upstaging him and tries to undermine her by letting Wangnan's group take out Cassano. Subverted when this turns out to be a ruse to give them a Hope Spot.
- Expecting Someone Taller: Hoaqin is fairly short, which combined with pale skin and very feminine looks, does not help the ongoing debate regarding Hoaqin's gender. As a side note, while everyone else was kissing up to Hoaqin, this is the only thing Hwaryun took away from the encounter. However, Boro and several other people remark that he used to be taller.
- Fantastic Racism: He appears to have a profound disdain towards Guides; although he does recognize their useful abilities.
- For the Evulz: He's so powerful that he often doesn't need to resort to manipulations and engineered Hope Spots to achieve any of his goals, meaning he's just doing this to amuse himself.
- From Nobody to Nightmare: Occurs before the start of the story. Hoaqin went from an ordinary Regular from the 10 Great Families to one of the most infamous FUG Slayers in the Tower's history. It took direct involvement from the Princess(es) of Zahard to end his reign of terror.
- Godhood Seeker: He was and wants to return to being a god.
- Heel–Face Turn: His sadistic actions come to feel increasingly pointless, he cuts a deal with Bam's faction, and he eventually comes to a compromise with the souls he ate, resulting in him moderating his behavior and joining Bam's side.
- Hero Killer: He eats Prince in Season 2 Ep 227.
- Hoist by His Own Petard: The soul vault on the Floor of Death acts as a Soul Jar, giving the residents immortality in return for keeping them trapped on that Floor. He steals said souls to augment his power and falls underneath the same Curse as a price.
- Jerkass: While few Regulars can claim to be saints, Hoaqin is by far one of the most openly sadistic and callous, to the point where he makes Rachel seem Affably Evil by comparison.
- Light Is Not Good: His first appearance, he is extremely pale and white and glows amid darkness.
- Manipulative Bastard: While he could probably kill all the ticket holders by himself, he prefers turning them against each other instead. And that's nothing compared to the way he pitted two countries, both of which he ruled and one of which he created, to engage in unending war so he can eat more souls.
- Master Swordsman: Comes from a Great Family that is gifted in swordsmanship and can wield his sword in high densities of Shinsu without resistance.
- The Napoleon: He does not take it well when someone comments on his height, even if they're a FUG higher-up.
- Only One Name: Only known by the name Hoaqin, and as far as we know that is only an alias he uses.
- Pintsized Powerhouse: Short, yet is both shown and regarded as a monstrously powerful Slayer candidate looked upon favorably by the FUG leadership, and who may or may not be an actual FUG Slayer in hiding. After he absorbs most of his siblings, he becomes a lot taller.
- Power at a Price: Doing a Fusion Dance with his brothers means he'll die of hunger unless he feeds on souls.
- Really 700 Years Old: He is at least 600+ years old.
- "The Reason You Suck" Speech: He delivers one to Cassano for letting his emotions get the better of him in his fight against Wangnan.
- Sealed Evil in a Can: Sealed parts of himself in the Train after massacring everyone on board, barring five Regulars.
- Shrouded in Myth: FUG doesn't divulge much information about him.
- Sibling Fusion: He's attempting to do this with his siblings, unfortunately for Bam who could barely survive against him at his weakest.
- Sibling Rivalry: Fusing with his siblings means only one personality can be active, which causes Vicente to turn against him so he can be the dominant personality instead.
- The Social Darwinist: While this belief is already present throughout the tower, Hoaqin takes it to extremes by sacrificing nearly everyone he can find to empower himself.
- The Sociopath: He feels no guilt for all the people he killed or siblings he tricked, is very manipulative, likes to toy with his food (aka other Regulars), is only out to become powerful, sees his allies as disposable pawns, and believes emotions get in the way of his goal of becoming a true "weapon". The only possible subversion is that he might genuinely love his father enough to want to surpass him.
- Soul Power: According to Daniel, he controls souls and used his power to split his own into parts before hiding them in different places on the Hell Train. He also feeds on souls to make himself more powerful and to regain his strength.
- Start of Darkness: Became the monster he is today because of his desire to surpass his father, and his father telling him that if he wanted to surpass him he should leave the family and return as a demon.
- Surrounded by Idiots: He openly insults the remaining members of his team for failing to defeat Aguero.
- There Is No Kill Like Over Kill: What he's most infamous for to be considered such a threat.
- Took a Level in Badass: Since he's lost his original strength as FUG Slayer White, Hoaqin spends his Tower journey trying to return to his original form.
- During the Dallar Show Story Arc, he gains some of his power back after absorbing three of his siblings (Vicente, Anna, and David) into his body.
- During the Floor of Death Story Arc, he gains even more of his power back after absorbing the stored souls of everyone living on the Floor of Death. However, this one doesn't stick due to the Floor of Death spell.
- Used to Be a Sweet Kid: When his father told him to become a demon, he originally interpreted it to mean he should make his father proud by becoming a benevolent ruler that looks after his subjects. But his father affirmed that he really did want his son to become a monster.
- Villainous Breakdown:
- Vicente and David manage to stab him, allowing the former to attempt to absorb him. Hoaqin then goes through this trope, only to subvert it when he reveals that the spell will only allow him to be the dominant personality. Afterwards, Hoaqin absorbs both of them and becomes even stronger.
- He has a real one when Bam starts using the power of his victims against him.
- He also breaks down when stealing the souls of the Floor of Death damns him to the same curse as the rest of them, leaving him trapped.
- Walking Spoiler: Trying to discuss things about Hoaqin is tough without giving away details surround his FUG Slayer White status.
- War for Fun and Profit: He actually created an entire country in order to go to war with the one he previously took over, just to start wars and gain more souls. And if those countries ever try to reconcile, he'll be sure to egg them back into fighting.
- "Well Done, Son" Guy: He and his siblings were neglected by their father for their lack of strength, causing them to take extreme measures in order to surpass him and gain his recognition.
Vicente
Vicente
When I become a Slayer, I will cut off our Father’s head and make him look back at me once again.
The second of five siblings that have been sealed aboard the Hell Train.
Vicente first encounters Wangnan and Ehwa on the Hell Train, but decides to fight against Hoaqin after befriending the two, and hopes to eventually replace Hoaqin as the dominant persona.
- Because You Were Nice to Me: He protects Wangnan and Ehwa because they gave him snacks.
- Cool Sword: Silver Moray, a gift bestowed to him from his father.
- Curtains Match the Window: Silver hair with silver eyes.
- Deal with the Devil: How Vicente sees Hoaqin's role in their becoming of White. He recalls the moment that Hoaqin mentioned the idea of fusing as a "whisper of a demon" but adds that he "held the demon's hand" anyway in order to gain more power.
- Everyone Has Standards: He has the same goal as Hoaqin in trying to surpass their father, but he isn't willing to commit mass murder just to gain the power to do so.
- Evil Versus Evil: He makes it clear that if he subjugates and replaces Hoaqin, he will be Bam's opponent for the test. Though this is subverted when he criticizes Hoaqin for all the deaths he caused in his quest for power.
- Enemy Mine: Though he later offers to side with Bam in order to take out and absorb Hoaqin.
- Master Swordsman: He seems to be evenly matched with Hoaqin. Makes sense since he's from a Great Family that are gifted in swordsmanship.
- Really 700 Years Old: He is at least 600+ years old.
- Sealed Evil in a Can: He's been sealed in the Hell Train. He also gets temporarily sealed by Wangnan using Khun's knife to separate him from Hoaqin.
- Self-Made Orphan: He wants to become one once he's strong enough to defeat his father.
- Sibling Rivalry: He stands against Hoaqin, because Wangnan and Ehwa offered him food, and because he wants to be the dominant personality when the time comes for the siblings to fuse as one body.
- The Starscream: To Hoaqin, now that he's no longer content with staying dormant while Hoaqin is awake.
Anna
Anna
Lets play, you guys...
The third of five siblings that have been sealed aboard the Hell Train.
She randomly stumbles across Hoaqin and Rachel's group, and decides to join with them after learning that they had come across Vicente who she had been searching for.
- Curtains Match the Window: Silver hair with silver eyes.
- Extreme Doormat: Her primary character trait. She latches on to whatever the consensus of her bigger brothers is and sticks to it, regardless of how it negatively impacts her. Mainly due to confidence issues: she isn't what a scion of the Arie is supposed to be.
- Girls Love Stuffed Animals: Carries around a pink rabbit toy.
- Killer Rabbit: Her toy which turns into an anthropomorphic humanoid rabbit that wields a sword upon Anna's command.
- Nice Girl: According to Vicente to the point that she will listen to whatever her brothers tell her to do.
- Really 700 Years Old: She is at least 600+ years old.
- Sealed Evil in a Can: She's been sealed in the Hell Train.
- The Un-Favourite: If Hoaqin thought his position was low in his father's eyes, it was not a patch on how far in the back of the basement Anna's spot as "terrible swordswoman" was.
- Weak, but Skilled: Hoaqin mentions that because she was always weak, she had difficulty learning swordsmanship. As such, she learned sorcery to circumvent this problem and gained power this way.
David
David
Click here to see his possession of Wangnan
I also want to live my own life.
The fourth of five siblings that have been sealed aboard the Hell Train.
Introduced through Wangnan using body possession, David is revealed to have teamed up with Vicente in order to break away from Hoaqin.
- Curtains Match the Window: Silver hair with silver eyes.
- Establishing Character Moment: He makes quite an entrance introducing himself to Hoaqin through Ja Wangnan.
- I Just Want to Be Free: He agrees to help Vicente on the condition that he's exempt from the Fusion Dance, allowing him to live his own life.
- Loophole Abuse: David isn't actually a participant in the game, so he gets around this by possessing Wangnan, who is a player.
- People Puppets: Had perfect control over Ja Wangnan to speak to Hoaqin after using the White Heavenly Mirror to body-jump inside of him.
- Really 700 Years Old: He is at least 600+ years old.
- Sealed Evil in a Can: He's been sealed in the Hell Train.
Albelda
Albelda
The fifth of five siblings that have been sealed aboard the Hell Train.
- Chekhov's Gunman: Despite not having an actual appearance herself, she ends up being important because she ends up being the reason why Bam could use Haoqin's techniques. While the Arie swordsmanship techniques are exclusive to those from the family, since Albelda's blood runs through the clone, it allowed Bam to temporarily use Hoaqin's skills which he would normally not have been able to mimic.
- The Faceless: As a first appearance, you can only see a black silhouette of Albelda in the background during the sibling's flashback sequence of the Dallar Show. As they have already been subsumed by Clone, they're the only one of the "White" siblings we never meet.
Unknown Clone
I have been watching you for a lot longer than you think. Because the billions of victims you have made and their vengeful spirits, formed who I am, your new "Clone".
An entity who appears at the start of the Dallar Show's third round claiming to be Hoaqin's final clone despite him stating otherwise. The clone announces that she will join whichever Hell Train team proves their strength to her in the third Dallar Show round.
- Big Damn Heroes: She saves Bam and Akraptor from Hoaqin's attack and gives the protagonist yet another power up.
- Cool Sword: Choice of weapon appears to be a sword. Unsurprisingly.
- Girl in the Tower: She cannot leave the train, as she remains bonded to it. Even after expressing a wish to go with the 43rd Floor expedition team.
- Mysterious Past: At the start, whatever happened to Albelda, and why this new clone has appeared before Bam and Hoaqin's teams, remained unexplained. It was later revealed that Albelda is one of the many billions of souls that make the clone up.
- Our Ghosts Are Different: The reason Hoaqin doesn't recognize her as a sibling is because she isn't one. She's actually made of the billions of vengeful spirits of Hoaqin's victims.
- Sealed Evil in a Can: She's been sealed in the Hell Train. Subverted. She's more vengeful than evil.
- Secret Test of Character: After Bam decides to save every hostage, including Hoaqin's, she decides to side with him because he's the very antithesis of Hoaqin.
- Wild Card: She doesn't pick a side until she assesses both Bam and Hoaqin's characters.

- Green Thumb: His Shinsu abilities take on the form of thorn-bush vines.
- Goal in Life: Similar to the rest of his old team, Sachi stayed connected to the Hell Train in order to find out what happened to Roen. After finding out that Roen can't return, he has a new goal to stop Hoaqin at the 43rd Floor of Death.
- Magic Wand: Look's more like a magic-mace, but it's Sachi's weapon which summons his Thornbush Shinsu skills.
- Putting the Band Back Together: Convinced by Aka to board the Hell Train again after learning about Daniel's objective to revive Roen using Hoaqin's power. The two reunite with Boro at the next Hell Train pit-stop.

A D-rank Regular that was part of Boro, Aka, Sachi and Daniel's previous team who ended up getting killed on the Hell Train as a means to seal "White" within the express.
- Broken Bird: Started off happy with life going on Hell Train adventures with her team...until they came across Hoaqin. Any happiness was gone from her the moment she fell into Hoaqin's trap, and was forced to kill off one of his underlings.
- Character Death: Died in the past aboard the Hell Train to seal White on the Hell Train.
- Curtains Match the Window: Orange hair paired with orange eyes.
- Green-Eyed Monster: In an odd variant of this trope, Roen was jealous of Hoaqin for taking away the Hell Train from her team to the point of being unable to go on any more adventures with the friends in her team while Hoaqin was around.
- Heroic Sacrifice: She sacrificed her soul to seal Hoaqin in the Hell Train.
- I Did What I Had to Do: Roen was forced to kill one of Hoaqin's underlings after he caught on to Roen knowing how Hoaqin and his most loyal underlings have been killing the weaker Hell Train ticket holders. It got to the point of no return once the underling started threatening Roen's teammates.
- Love Confession: Confesses to Daniel the night before her Heroic Sacrifice.
- Mission Control: She was a Light Bearer.
- Morality Chain: Can be seen as such for the above mentioned Hell Train team (particularly towards Daniel) in order to keep the team in line to the point of calling her teammates out if they did something wrong.
- My God, What Have I Done?: Roen is shaken up upon realizing that she killed one of Hoaqin's underlings aboard the Hell Train.
- Posthumous Character: Her role in the story serves to motivate Daniel's actions in the current day. Her being dead is also what kept Daniel, Boro, Sachi, Aka, and Poro, connected to the Hell Train for hundreds of years.
Poro Poe
Poro Poe
Daniel! You must bring Roen back to life! Got it? If she comes back, we’ll be able to climb the Tower again all together.

- The Announcer: Acts as the referee for the Dallar Show between Bam and Rachel's teams aboard the Hell Train.
- The Beastmaster: He is usually accompanied by a dog-like creature.
- Butt-Monkey: Was treated as such during the Past Team flashback. Daniel basically curb-stomped him, and he was being picked on by one of Hoaqin's underlings aboard the Hell Train. An underling who would be later killed by Roen for abusing Poro.
- Dark and Troubled Past: He happened to be one of the Regulars that was around during the Hoaqin incident which is most likely why he appears to be working with Daniel to try to resurrect Roen.
- The Dragon: Works second to the conductor of the Hell Train, Pedro.
- The Starscream: However, Poro is working against Pedro to help Rachel's team take the train for themselves, which could then be argued that he is actually working with neither just to help with Daniel's objective.
- Thousand-Yard Stare: His eyes can come off a bit...unsettling.
Team Bero
Bero Bero
Bero Bero
Tower Position: Fisherman
You are thin!! Pretty!! Have nice hair!! And also have the incredible power worthy of the 10 Families!! But, it's not like I'm jealous of that!! You have to eat less to stay slim!! Guys are gonna bother you if you are pretty!! And if you are strong, there should be a lot of things you must take responsibility for!! So, stop being so ridiculous!!
A fat D-rank Regular that leads a group trying to board the Hell Train. Bero's team first appears as one of the teams who took part in the 35th Floor's Train City tournament. Alongside Rak, Bero's team is finally able to board the Hell Train at the 37th Floor's Wooden Horse pit-stop, and join up with Bam's team to fight against Rachel and Hoaqin's group in the Dallar Show. Instead of joining Bam's 43rd Floor expedition group, Bero decides to stay on the Hell Train to look after the billion-soul White clone, but rejoins them once it's time to get off.
- Acrofatic: Bero Bero's a fat character, but she can fight just as well as anyone in this series. Surprising everyone, she was able to fight Buelsar to a draw in the Dallar Show's first round.
- Alliterative Name: Last name is the same as the first.
- Early-Bird Cameo: Briefly appears with the rest of her team watching the "Crazy Ball" match between Bam and Yura's groups.
- Get A Hold Of Yourself Man: After a berserk Ehwa defeats Angel during the Dallar Show with her overwhelming Yeon flames, Bero is able to convince her to snap out of it before anything worse happens.
- In-Series Nickname: After she joins Bam's team, most members just default to calling her "Candy".
- The Leader: Of her Hell Train team.
- Little Bit Beastly: It's not very noticeable, but Bero has a lizard-like Prehensile Tail under her dress.
- Oh, Crap!: Spends a lot of time pulling these faces as she realises how underpowered she actually is in comparison to the real monsters she's found herself surrounded by.
- Power-Up Food: Her means of powering herself up is chomping down on a giant lollipop.
- Put on a Bus: While she hasn't quite disappeared, Bero stays on the Hell Train instead of taking part in Bam's trip to the 43rd Floor in order to look after the Hoaqin clone. She comes back along with Iruroe for the Hidden Floor arc.
- Revenge: Her team actually had a fourth member (Tochi) that was quickly killed off by Buelsar after her group was finally able to board the Hell Train. Obviously, she wants revenge against him for his death.
- Ship Tease: Hockney seems to have taken a liking to her, which she has no issue with.
Phonsekal Iruroe
Phonsekal Iruroe
Tower Position: Wave Controller
I'm walking the path that you wanted for me, uncle. I've even found the key to opening the door of my dreams.... Him... that boy.
One of Bero Bero's D-rank teammates who floats around on a pillow. Iruroe is from the same family as Lauroe, which is made obvious by her constant need to sleep. Following the Hell Train's Dallar Show, Iruroe is one of the Regulars that joins Bam's group to journey to the forbidden 43rd Floor.
- Blow You Away: Her powers, on the rare occasion when she actually uses them, seem to edge this way.
- Brilliant, but Lazy: She's shown to have good Shinsu reading abilities, and can attack using Shinsu as a Wave Controller...as she lays down on top of her pillow.
- Color Motif: Just look at all that pink.
- Early-Bird Cameo: Briefly appears with the rest of Bero's team watching the "Crazy Ball" match between Bam and Yura's groups.
- Flight: She can float atop her pillow.
- In the Blood: OK, so she doesn't wrap up in a blankie and do the snuggle bug like Lauroe does, but it's pretty obvious that any Phonsekal residence is likely to be a very quiet place the vast majority of the time... They're a bunch of Shinsu-reading Snorlaxes.
- In-Universe Nickname: Cherry La
- Out of Focus: Iruroe has been traveling alongside the rest of Bam's group ever since the end of the Dallar Show, but hasn't yet had a single moment of focus. While she does get a minor fight with her Sworn Enemy (an apparition of her uncle) during the Hidden Floor arc, she otherwise doesn't do anything notable.
- Suspiciously Similar Substitute: Her role is basically the Hell Train saga's version of Phonsekal Lauroe from the Floor of Tests. To no one's surprise, Iruroe turned out to also be a member of the Eurasia branch family when her full name was said at the Name Hunt Station.
Pompidou
Pompidou
Tower Position: Light Bearer
What do you think you're doing to a noble lady from the Ten Families? Where are your manners?

- We Hardly Knew Ye: He dies before the reader ever got to know anything about the character.

Felix
It looks like I'm too injured to take part in the Tournament. I'll only be a burden to all of you.
A D-rank Regular, and one of Boro's two Shinsu students alongside Hanool. Unlike Boro and Hanool, Felix did not become a part of Bam's Hell Train team due to an injury she received from the blue-lizard Ticket Hunter.
- Ambiguously Brown: Brown skin.
- Game-Breaking Injury: She takes a major blow to the chest from the blue-lizard Ticket Hunter that attacked her, Boro and Hanool on the train that was headed for Train City, which results in her weak state throughout the rest of the arc. Her injury is the reason that Boro chose not pick her as a part of Bam's Hell Train team.
- Lady Looks Like a Dude: Due to a masculine look, and lack of any noticeable features, a lot of readers thought Felix was a man at first glance until the author started referencing Felix as a woman. It was also during this time that SIU started drawing Felix with more "womanly" quirks.
- Put on a Bus: Unlike Hanool, Boro does not take Felix along with him to attempt to board the Hell Train again on the 37th Floor due to her injury, and was forced to stay behind.

- Student–Master Team: The student to her master, Boro.

- Wrong Genre Savvy: Believed his 35th Floor team had the match in the bag due to how small Bam's group looked. Bel failed to realize during the Floor test that Bam was a lot stronger than he looked.

- Character Death: Dies in a fight against Boro.

- No Name Given: Neither were given names.
- Oh, Crap!: Seeing the massive soul-shinsu attack that Hoaqin's amassing above him to kill his opponents, the two of them quickly realize that they're screwed. They try to make a run for it only for Hoaqin to kill them off with the soul-shinsu bomb as if he struck them down with a bolt of lightning.
