Walter Park Arc Summary
Chapter 69: Enjoying Our Final Days
Iruma remains at home not knowing what to do for his summer vacation. That is until Azz and Clara show up at his house. They desire to take him to Walter Park knowing of his interest in going to an amusement park, which they brought along a park guide to plan out their day of fun. Clara then reveals that she had already asked everyone else to join in; resulting in the rest of the Abnormal class arriving at Iruma's home ready to go to Walter Park with him, which they help out at putting together the day plan. Sullivan is also highly interested in letting Iruma have his day of fun, and makes sure to provide his grandson a few capable escorts.The next day, Iruma, Azz, and Clara meet up with a majority of the Abnormal class at the closed entrance of Walter Park. Schneider being the only one who couldn't make it as it turned out that his top grades got him selected to be the school representative for an academic conference. Opera, Shichiro, and Kalego are also seen waiting on standby as the mentioned escorts; having been ordered to watch over Iruma and company during their time at the park. Iruma is then greeted by Ameri, who Iruma texted ahead of time about the park trip. Ameri ended up getting the trip confused as a private date with Iruma, but in the end is still prepared to have a day of fun with him and his class. Eventually, the gate to Walter Park opens. Iruma and company are welcomed by the workers as they enter to begin their day of fun.
Chapter 70: Walter Park
As everyone prepares to go off on their own, Kalego makes it clear that the students will all need a chaperone watching over them. Shichiro suggests that they split into 3 groups given the 3 adult escorters present, which Clara adds that they should turn this into a competition to see which group by the end of the day turned out to have had the most fun. They all agree to go along with it, even Kalego so long as the losing team gets punished with more summer homework. Drawing straws for the teams, Shichiro gets Iruma, Azz, Sabro and Picero, Opera gets Clara, Ameri, Kerori, and Elizabetta, and Kalego gets Jazz, Lied, Goemon and Kamui. The last of which are all left in despair that they've already lost getting paired up with Kalego.The 3 groups all head off to begin their day of fun. In Opera's group, Ameri remains disappointed that she didn't get paired with Iruma, but the other girls are excited for the all-girls reunion, and decide to go shopping with Ameri to buy her a dress. Meanwhile, Kalego's group tries to plan behind his back feeling they can't win, but return to taking the fun competition seriously when Kalego spots them acting weird. Finally, Shichiro's group has basically become a sight-seeing event for Iruma given that he's never been to an amusement park before. While watching a parade however, Iruma and company run into Ronove again showing off on one of the floats. Ronove greets his classmates, and explains how Walter Park is his sanctuary that his father built for him. With Ronove is his subordinate, Huetoto, a member of the park staff trying to keep Ronove focused on inspecting the park for his future goals.
Ronove is told about the fun competition going on between the 3 teams, which sparks his interest. He offers to use his VIP status to provide Shichiro's group a tour of the park's most secret and dangerous places, which freaks Huetoto out hoping that Ronove's not talking about the park basement. It turns out that because Walter Park has a lot of attractions that require loads of magic to run, a massive prison for dangerous demons was built underneath the park; sapping the prisoners of their magic to run the park attractions. Meanwhile within said prison, Kirio is seen as one of the prisoners taking notice that the park seems more rowdier than usual.
Chapter 71: Everyone's Playmate
The 3 teams go about having fun within Walter Park. Opera's all-girls group of Clara, Ameri, Elizabetta and Kerori is first seen having made their way to a clothing shop to pick out clothes. Here, two staff members, a lady with glasses and an old man barely taller than a foot, help them try on clothes; claiming that its their jobs as park staff to act as their playmates wherever and whenever. Opera's group then pose for a fun photo to show to the other groups the proof that they're having fun.Second, Kalego's group of Lied, Jazz, Goemon and Kamui go about struggling to have fun. They're eventually greeted by two thug-looking demons, who challenge the students to a shooting gallery game. The result is the students finally having some fun, which they pose for their picture to send to the other teams as proof. In addition, the two thugs reveal themselves to be members of the park staff acting out their role as playmates. The group suddenly starts receiving loads of pictures from Shichiro's side showing their fun, which leaves the Kalego team desperate to find a unique park location for them to have fun. Lied suggests Kararagi Street due to how mysterious it appears on the park map, but Kalego steps in warning them not to go there. He explains to his students how it's a leftover place from when the park was designed just for demons to vent out their wicked phase stress. That to this day, Kararagi Street remains as the park's area for demons who have bad reputation, and engage in shady activity.
Finally, Shichiro's group of Iruma, Azz, Sabro, and Picero go about having fun in the park while Huetoto struggles to keep up. Though their adventure is mainly just watching Iruma and Ronove enjoy themselves on the rides as Azz takes loads of pictures of Iruma to send to the other 2 groups. While having fun however, Iruma ends up not paying attention, and gets himself separated from the group. Having lost contact with the others due to his phone being out of energy, Iruma suddenly finds himself completely lost on the dark and dangerous looking Kararagi Street.
Chapter 72: Sharp Eyes
Ronove returns to Shichiro's group alone, which causes them to freak out that Iruma's gone missing. Meanwhile on Kararagi Street, a suspicious demon discovers Iruma, and tries to pull the boy into a dark alley. However, said demon is scared off by a tall female demon claiming Iruma to be her brother. The female demon then helps Iruma escape Kararagi Street by returning him to the bright safeness of Walter Park, scolds the boy for doing something so dangerous, and points Iruma in the direction of the park's lost kid center. However, she chooses to stick by him worried that he's going to get lost again along the way.Iruma's attention is brought to an animal riding attraction where he goes about riding a critter for fun. However, Iruma notices that the female demon struggles to interact with critters, which he shows her how to befriend critters based on what he learned from Shichiro's teachings. The two of then pose for a picture as a way to remember this moment. Iruma and the female demon next go on the ferris wheel when she suggests that they can see the correct path to take towards the lost kid center from high up. Here, Iruma thanks her for all the help she's given him so far, and that meeting her made him glad to have come to the park. In return, she happily pats him on the head.
Spotting Shichiro's group from above, Iruma reunites with his friends after getting off the ferris wheel, much to their relief. However, the female demon disappears before Iruma could properly introduce her to them. The female demon arrives at a backstage area of Walter Park where she's revealed to be a member of the park staff named Shiida. Despite being scolded by another worker to not leave her position like she just did, Shiida is only interested in the picture she took with Iruma having played out her role as a part of the park's staff.
Chapter 73: Wlavoas Prison
The story switches to following Imp Rocky, a newcomer detainee within the Wlavoas Prison fortress beneath Walter Park. Imp along with many other prisoners are brought to a machine where their magic power is sucked out, and sent up to power the park. Amongst his fellow prisoners is Kirio serving his 2 year term, who's struggling to provide magic due to his weak constitution. A fellow prisoner named Bats picks up Kirio to take him to the sick bay, but also takes Imp along, much to the latter's confusion. Instead of the sick bay however, Bats takes them to a secret location where a group of the prison's most wicked demons are all gathering.Once Bats arrives with Kirio and Imp, the prisoners begin the meeting. As the newcomer, Imp is let in on their plan of escaping the prison. The plan came to fruition as a result of Kirio being an acquaintance of the "Six Fingers;" an infamous group of 6 dangerous demons who follow the primal demons, and made a name for themselves causing several noteworthy incidents. The Six Fingers have decided Walter Park to be their next target, which they currently reside within the park to help Kirio and the prisoners escape once they begin their "festival."
Bats explains to Imp that the magic power they've been sending up to Walter Park has been changed to not go towards the attractions, but is instead going to places set up by the Six Fingers. That whatever the Six Fingers set up, the magic power they've been storing up at these locations is going to be used to destroy Walter Park, which will provide them an opening to escape. Imp then hears that the plan is all going down today as Kirio shows off his wicked side smiling ecstatically at the thought of all the cheering park visitors suddenly screaming in despair. Meanwhile, Iruma is seen being happy in Walter Park not knowing that something bad is about to happen.
Chapter 74: The Six Fingers' Plan
Iruma goes about entertaining some young kids as a bit of punishment for getting himself lost while the rest of Shichiro's group watches. He also learns about the existence of the Six Fingers from Azz. The kids also play with Picero, which eventually results in Ronove pulling off Picero's eye mask. To the surprise of everyone, Picero turns out to have been a dazzling good-looking boy behind the mask. Huetoto then departs from the group needing to report back to staff headquarters.At staff headquarters, Shiida is seen waiting for Huetoto. He asks if the plans are ready, which she states is the case, and are just waiting for Wett's orders. Making their way to a rooftop, Shiida gives Huetoto a walkie talkie, which he gives the order to those on the other side to stop being staff members and return to their duty as the Six Fingers. Thus, revealing that Huetoto is Wett (First Finger), and that Shiida (Second Finger) is also a member. On the other side of the walkie talkie, the four staff members that were helping the Opera and Kalego groups turn out to be the other Fingers. The two shopkeeper Fingers being Hyudarin (Third Finger) and Miki (Fourth Finger), and the two thug Fingers being Atori (Fifth Finger) and Maemaro (Sixth Finger). They all remain excited that they finally get to drop the act to return to making chaos as Wett announces that due to the staff managers all being away from the park at the moment, this is their best chance to strike and free all the Wlavoas prisoners.
Aiming to destroy Walter Park, Wett is now holding in his hand an egg-shaped object. In addition, two similar egg-shaped objects are seen being held by Hyudarin and Maemaro to begin the plan at their locations. Wett drops the egg object off the roof, which results in a large explosion once it hits the ground. Many of the visitors get caught up in the explosion, along with Shichiro's group as they appear out of the rubble. Iruma and company are left stunned at the sight of a massive dragon monster appearing out of the explosion, and begins destroying the park. Thus, revealing that the Six Fingers' plan is to destroy Walter Park with 3 large rampaging demonic beasts.
Chapter 75: Demonic Beasts Raid
Moments beforehand, Shichiro's group are seen cleaning up from entertaining the younger kids only for Picero to notice that something is off being able to sense 3 strange concentrated magic abnormalities going on in the ground. The moment Wett drops his egg object to the ground, the concentrated magic from the prisoners activates the spell that hatches the egg. Picero instantly notices, and activates his My Area bloodline ability to raise the ground up and project Shichiro's group from harm. The group then looks upon a newly hatched massive Carmine Dragon in their area going about rampaging and destroying the park. Iruma then recalls how Picero mentioned that it wasn't just one magic abnormality he sensed.Sure enough, two other gigantic demonic beasts are seen now rampaging through Walter Park; a Panther Rat at the location of Opera's group, and a Mountain Bull at the location of Kalego's group. The announcement from the staff is made for the visitors to begin evacuating, but Kalego chooses to stay as he hasn't gotten to have fun. Believing that he shouldn't miss such a good teaching opportunity, Kalego aims to use this disaster as a means to improve his students' teamwork. Thus, Kalego gives the order to his group of students to go all out with their demonic power to take down the rampaging Mountain Bull, much to the fear of Lied, Jazz, Goemon, and Kamui.
Chapter 76: A Reliable Back
Kalego's group of students try to take on the Mountain Bull, but are struggling due to Goemon being the only one with an offensive bloodline ability while Lied, Jazz, and Kamui all have utility bloodline abilities. Jazz forms a plan using their teamwork where Lied uses his Controller bloodline to take away the Bull's eyesight, Kamui uses his Translation bloodline to keep the Bull focused on him by speaking the Bull's language, and then Jazz combines a simple fire-spell with Goemon's Wind Blade bloodline to launch a combined fire/wind blade attack at the Bull from its blind spot. However, the attack does no damage on it. The four of them look to Kalego begging the teacher for help, but he remains on standby ordering his students to continue, and overcome the obstacle in front of them, if they desire to get stronger.Unlike Kalego, Opera battles it out with the Panther Rat as it's his duty to protect Iruma's friends, much to the amazement of Ameri, Clara, Kerori, and Elizabetta. Ameri is ordered to evacuate the others to a safe location while Opera continues to to hold off the Rat. As they fight, the Panther Rat catches Opera by surprise when it reveals to have eight tails to attack with instead of one. One of the tails is about to finally hit him, but Ameri returns to kick the tail away; claiming that she can't run away from a crisis needing to do her duty as Babyls' Student Council President. Opera and Ameri stand back-to-back ready to take on the Panther Rat together only to become confused when they spot a returned Clara now holding on to one of the Rat's tails.
Chapter 77: This Feeling Is...
Unlike the Kalego and Opera groups, Shichiro's group is seen evacuating with the other visitors from the area of the rampaging Carmine Dragon. However, Iruma is unable to understand the pain he's feeling in his chest looking upon the destoryed rubble of the park. A young boy trapped in the rubble suddenly cries out for help, along with calling to help the other children still stuck in the debris. However, none of the visitors are interested due to the danger of the nearby Carmine Dragon, and because demons have no interest in helping if they don't get anything in return. Looking at a phone picture of him and his friends having fun in Walter Park, Iruma realizes that the pain he's feeling is that he's sick of the horrible things going on around him, and because no one is doing anything about it. The result is Iruma charging in alone towards the rubble to save the trapped kid, much to everyone's surprise.The Carmine Dragon rampages near Iruma and the trapped kid, but Iruma is able to easily avoid all the falling rubble due to his evasion skills, and saves the young boy. Iruma then announces to the rest of the Shichiro group that he feels irritated due to everything falling apart after having a fun time with everyone. Thus, he announces that he will strike back at this crisis by saving the kids, and proceeds to go deeper into the rubble. Meanwhile, Shichiro's group is impressed by Iruma's determination, which they all follow after Iruma into the rubble to help save the kids. Ronove is also brought along, much to his inconvenience. Meanwhile within Wlavoas prison, the Six Fingers begin disposing of the 1st floor wardens as they make their way down towards rescuing one specific prisoner.
Chapter 78: Older Brother's Pride
Chaos erupts within Wlavoas Prison as the Six Fingers fight their way down into the prison's 2nd floor. Here, they disable the mechanism that keeps all the cell doors locked, which releases all the prisoners on the 3rd and 4th floors. As the battle ensues between the guards and the escaped prisoners, the group of prisoners who teamed up with Kirio are all seen making a break for it running up from the 4th floor. However, Imp remains worried and unconvinced of escaping since they're going to eventually have to deal with Triton, the powerful Deputy Warden known to easily crush their arms and legs thanks to his Handshake bloodline ability where he can crush anything with his hands.Bats and the other prisoners of the Kirio group are all convinced that the Six Fingers are going to have a fierce battle against the deputy. Unbeknownst to them however, Triton is easily defeated by the much stronger Hyudarin, who Handshake had no affect on. The Fingers have finished clearing out the 2nd floor of the guards, and are about to go down to the 3rd floor as they hear their demonic beasts continuing their rampage above. Wett figures that it would take the appearance of a hero to stop Walter Park from being completely destroyed.
On the surface, Kalego's group continues their fight against the Mountain Bull. Lied, Goemon, and Kamui look to Jazz for help given that the latter is the Rank 3 (Gimmel) demon while the other three are only Rank 2 (Bet). The thought of being relied on as if he's their older brother makes Jazz extremely happy as he had decided in the past to treat his future younger siblings nicely compared to all the bad experiences he's had dealing with his own older brother. Overall, Jazz accepts the role as the group leader, but is unable to think of a plan that combines their abilities. Still watching from afar, Kalego provides a hint to his students asking Jazz if the whistle tied around his neck is just for show. Upon checking his whistle, Jazz realizes that he has a plan to win.
Chapter 79: Victory Roar
Lied, Goemon, and Kamui go along with the plan devised by Jazz to beat the Mountain Bull. Thanks to the Translation bloodline also having the ability to control living things, Kamui takes control of hundreds of demon birds from the park's aviary to distract the Bull for his teammates as they work their plan. Jazz, Lied, and Goemon ride up on one of Kamui's mind-controlled birds towards the Bull's head, which Lied uses Controller to steal away the beast's hearing to further keep it distracted. Meanwhile, Goemon uses Wind Blade to redirect any strike the Bull sends their way.All their efforts allow for Jazz to jump off the bird onto the Bull's ear, which he pulls out his whistle known as an Ear Blast Flute. The whistle is said to emit a powerful head-splitting sound wave against enemies depending on the strength of the user. Jazz's older brother had given it to him as an escape tool if he was ever caught trying to steal something, but Jazz instead decides to use it to stop the Bull's rampage. The moment Lied turns off Controller to restore the Bull's hearing, Jazz blows the Ear Blast Flute into its ear; sending a loud sound wave into its head, which successfully knocks out the Mountain Bull. The four of them begin celebrating believing to have won the battle, but are caught off-guard due to the Bull waking up moments after.
The Mountain Bull attempts to strike while the students aren't looking only for Kalego to finally step in and block the attack with a barrier. Kalego scolds his students for prematurely celebrating before fully confirming that they've won, but he still provides them passable enough grades for coming up with a plan that kind of worked. The teacher then proceeds to summon out his Cerberion familiar to quickly curb-stomp the Bull. With the Mountain Bull finally defeated, Kalego orders his students to finally take his picture now that he's had fun.
Chapter 80: Which Side Is The Strongest?
Kerori and Elizabetta are seen within Walter Park's emergency shelter trying to help the staff keep the visitors and little children calm while the demonic beasts rampage outside. Kerori then comes up with an idea, and goes off on her own. Elizabetta struggles trying to keep everyone calm despite her Favorability bloodline being on full-blast, which they all begin to panic in fear. The moment Elizabetta's about to fall apart, Kerori returns having dressed up in her idol outfit as Kuromu.The sight of Kuromu grabs the visitors' attention remembering that the idol was supposed to have a concert at the park today. Kuromu then takes the stage begging everyone to calm down and think rationally again. She asks them the question which is stronger: their fear of the demonic beasts, or her cuteness, which they all begin to cheer in excitement that Kuromu's cuteness is stronger. With the help of the staff, Kuromu begins her concert within the shelter to keep the park visitors calm and happy.
Meanwhile, the fight with the Panther Rat continues, which Opera notes that the Rat appears to have a weak spot on its forehead. Ameri steps forward to take on the Rat herself while Opera goes in to rescue Clara, who's still being swung around hanging on to one of the Rat's tails. Once Clara is rescued, Ameri gets serious for the first time by strengthening up her magic to full power. Ameri then states to the Panther Rat that she will now show it the power of the Rank 6 (Vav) demon, Ameri Azazel.
Chapter 81: The Invincible Maiden
The Panther Rat senses the danger of facing a powered up Ameri, and begins to change up its tactics, such as trying to crush its enemy by jumping on her. However, Ameri easily throws the Panther Rat back as it turns out that what she activated to reach full power was her Romanticist bloodline; a magic said to be the strongest buff magic of her Azazel Family that allows for Ameri to draw out her maximum power as long as she believes in her own strength. The Panther Rat changes tactics again trying to spray poisonous gas upon Ameri, but it has no affect on her aside from making her act a bit out-of-sorts, such as randomly starting to sing. Ameri ends up thinking about a time where she was in a concert audience watching an Akudol perform, which the idol's words about burning spirit and not giving up has continued to inspire her.While thinking and singing about the idol words that a maiden in love will never lose, Ameri lands a powerful flaming kick upon the Panther Rat's weak forehead spot that Opera told her about. The Panther Rat is finally defeated, but Ameri is left suffering the intense backlash from using Romanticist. Opera praises Ameri for a job well done, and that she's still capable of becoming stronger. He offers her to come work and train at the principal's house once she graduates school. Ameri declines the offer at first, but quickly realizes that she would be living under the roof of Iruma, the boy she fell in love with. As a result, Ameri changes tune that while she's already decided on her career path to help with her father's work, she hasn't taken Opera's offer off the table just yet.
Switching his attention to Clara, Opera finally gets around to asking her why she came back. Clara explains that she believed her Summon bloodline would be helpful to make weapons for them, which gives Opera an idea as he proceeds to ask her to make for them a secret weapon. Meanwhile at the location of Shichiro's group, the Carmine Dragon continues its rampage. Azz and Sabro are seen on a nearby rooftop ready to fight it while ordering each other to not get in the way.
Chapter 82: Fighting Duo
Led by the little boy he rescued earlier, Iruma manages to locate the trapped kids under the park rubble with the help of Shichiro and Picero. They begin making their way to getting the kids to a safe location, which Iruma remains worried about Azz and Sabro given that they went off to fight the Carmine Dragon. Shichiro assures Iruma that he ordered the two of them to just act as decoys to distract the dragon until they've rescued the kids, but they quickly spot nearby that Azz and Sabro have already begun battling it out with the demonic beast. Azz and Sabro show off their respective fire and Weapon Creation attacks against the Carmine Dragon arguing over who's doing better to the point that they both summon out their familiars to deal more damage.Despite the added firepower of Azz's Gorgon Snake and Sabro's Kelbie, the Carmine Dragon remains fully capable of fighting. However, the efforts put up by Azz and Sabro is enough to impress Shichiro into believing that the two of them are already proving themselves to be terrifying first-year students. At this point, the Carmine Dragon changes tactic to start using its breath attack. It fires a massive beam of magic that hits the building Iruma's company were moving through, but Shichiro easily blocks the attack from hitting Iruma and the kids. The Carmine Dragon then turns its attention to Azz, and fires another beam of magic that appears to overtake him.
Chapter 83: Indestructible Spear
Azz is shown to have been protected from the Carmine Dragon's beam attack thanks to Sabro getting in the line of fire to block it with a shield he quickly forged up. However, Sabro is left in a rough state due to the beam melting through the shield. Azz remains confused as to why Sabro saved him, which Sabro stays true to himself claiming that pulling such a stunt makes him an extremely cool Demon King. The two of them take cover behind a wall when the Carmine Dragon attempts to hit them with a fire-breath attack. Azz stands ready to continue the fight, but Sabro suggests that they retreat. Azz is left confused by Sabro choosing to run away, which Sabro questions if fighting and dying to the demonic beast is truly Azz's ambition.Sabro points out that unlike Azz, who hasn't grown a millimeter by always being distracted by Iruma, Sabro's been using his experiences up to this point to reflect on what he did wrong in order to mature, and to continue growing stronger towards his goal of one day becoming the Demon King. He yells at Azz calling him an idiot for not remembering that his ambition was to be Iruma's indestructible spear rather than just dying gloriously to a demonic beast, which finally convinces Azz to retreat so that he can return to Iruma. Using the last of his remaining magic power, Azz casts out a long Flame Wall for him and Sabro to run along so that the Carmine Dragon can't see them escaping the area.
While running along the Flame Wall, Azz stubbornly thanks Sabro for the earlier shield save. Sabro accepts it calling what they're currently doing the coolest, but he warns Azz that he's completely exhausted of magic as well. The Carmine Dragon is then able to spot them through the Flame Wall, and proceeds to fire its powerful magic beam at the exhausted duo. However, they're saved by the arrival of Shichiro blocking the attack. Shichiro praises them for their survival efforts, and gets ready to take on the Carmine Dragon himself.
Chapter 84: The Gargoyle Bears His Fangs
Iruma and Azz have a tearful reunion saying sorry to one another. Iruma for his actions putting Azz in danger, and Azz for forgetting about his ambition to be Iruma's spear. Afterwards, Sabro reminds them that they all got to start running due to the fight that's going down between Shichiro and the Carmine Dragon. Shichiro uses his demon biology knowledge to create a large Wooden Dragon from Nigi-Nigi weed in order to take on the Carmine Dragon in a duel between massive dragons. The Wooden Dragon goes about entangling the Carmine Dragon in roots at its weakest points. As for the Carmine Dragon, its fire-breath has no affect on the Wooden Dragon due to it being buffed by Shichiro's powerful mana. Shichiro's Wooden Dragon then lands a fatal bite on the Carmine Dragon's neck; resulting in it finally falling over in defeat.Shortly after, Shichiro's students reunite with him. The defeat of the Carmine Dragon impresses Azz and Sabro to the point of wanting Shichiro to be their mentor, much to Shichiro's surprise that he now has students who look up to them. The corpse of the Carmine Dragon then begins to act up as if its leftover magic's calling for help. Sure enough, the leftover magic from the defeated Mountain Bull and Panther Rat beasts rise out of their bodies. Their magic flies off, and gets absorbed into the Carmine Dragon; resulting in the dragon transforming into a larger Mutant Demonic Beast that wakes up and stands ready for another fight.
Shichiro orders his students to retreat, which he takes the full blast of the Mutant Demonic Beast's magic beam. However, he's saved by the arrival of Ameri and Opera, who support Shichiro in blocking the magic beam. Thanks to Sullivan dumping a unique smelling perfume on Iruma before heading off to Walter Park, Opera knew how to find Iruma. Opera and Sullivan decide to team up like old times, but Opera remains convinced that they're going to have a rough time against the Mutant Demonic Beast just being the two of them. Thus, he pulls out a summoning seal (the secret weapon Clara made for him), much to Iruma's fear knowing what Opera's planning.
Chapter 85: Last Trick
Iruma uses the seal provided from Opera to summon Kalego in familiar form to their location. Despite Kalego being angry about being in familiar form again, Opera convinces him to combine their efforts with Shichiro so that the three adult demons can take down the Mutant Demonic Beast standing before them. Unsurprisingly, the three high-rank demons go about completely curb-stomping the beast into a quick defeat, much to the stunned shock of Iruma and company.Still moving through Wlavoas Prison, Wett gets word from Miki watching the park above ground about the defeat of the demonic beasts, which surprises him that the beasts have already lost. Atori questions how they're supposed to complete the plan of destroying Walter Park, but Wett remains convinced that they just got to speed things up on their end. Wett assures Atori that given how the Mutant Demonic Beast was bred from their wicked magic, it has one last trick to destroy the park. Sure enough, the magic within the beast begins to expand and gain power, which Iruma and company realize that the defeated Mutant Demonic Beast is turning itself into a bomb for one final self-destruct explosion.
Iruma and company all jump into a hole made by Picero's My Area ability for shelter from the incoming explosion. However, they notice the head of the Mutant Demonic Beast aiming towards a specific location to shoot its self-destruct magic at; realizing that it's aiming to destroy Walter Park's emergency shelter that the visitors are holed up within. Iruma remains desperate for a plan to save them, but Shichiro makes it clear to him that no matter what, they'll be too late. As the Mutant Demonic Beast is on the verge of firing its self-destruct magic, Ronove steps out and yells at it for hurting his park and people. Thanks to Ronove's Charisma ability, he forces the beast to turn its attention towards Ronove, but he realizes he didn't think things through, and is now about to die. However, Iruma steps in front of him ready to defend Ronove. He calls upon Ali to help, which the ring spirit agrees.
Chapter 86: My Ambition
Iruma's plan is to use his Ring of Gluttony to absorb all the self-destruct magic. Despite being caught off-guard knowing how hard eating all the magic at once will be, Ali assures Iruma that he can do it as long as the boy helps him. Ali reminds Iruma of the time that he first taught Iruma how to imagine magic, and to do the same by imagining Ali in a form that swallows up all the magic. Thinking about all the experiences and fun he had at Walter Park, Iruma pictures a large cat in the form of a parade float with a mouth large enough to eat the Mutant Demonic Beast whole. The cat form Ali then proceeds to swallow up the entire beast, and drains it of all its magic. With the Mutant Demonic Beast finally defeated, Iruma raises his fist in victory acting like he did it all himself so that the others don't find out about Ali's existence.Everyone is relieved that Iruma survived with the exception of Kalego, who scolds the boy for, once again, throwing himself into a crisis without thinking about the danger. However, Iruma replies that he didn't forget about it since he was indeed feeling fear that the people most precious to him were going to get hurt. As a result, he chose to strengthen his resolve in order to stand before the Mutant Demonic Beast and save everything. He announces to Kalego that this is his ambition, which Opera thinks to himself that he's finally starting to understand why Sullivan chose him.
At that same time within Wlavoas Prison, the prisoner group that teamed up with Kirio is seen having made it up to the 1st floor. Bats notes the oddity that Kirio's missing, which Imp informs him that they got separated during the escape. The prisoner group climbs up a pile of rubble towards the last barred window blocking their way to the outside, but are shocked to realize that the bars are enhanced with magic to the point of repelling them backwards. Thus, keeping them stuck within the prison. Through the barred window, they spot Kirio coming out of a pipe having successfully escaped to the outside. In addition, the Six Fingers are seen waiting for his arrival. The prisoners call out to Kirio for help, but they soon realize they've been betrayed when Wett recounts the orders Baal gave them: to destroy the park, and to only free Kirio; meaning that the escape path the Six Fingers created was only for Kirio. Looking upon Kirio smugly smiling towards the still locked up prisoners, Imp realizes at that point that while the people within the prison were considered bad, Kirio was truly evil.
Chapter 87: Destined Enemy
Bats and the other prisoners are all enraged by Kirio's betrayal, which Atori agrees that setting them all loose would help throw the park into chaos. However, Kirio replies that betraying them at the last second was necessary as he desires to see them all fall to despair as they watch everything fall apart before their very eyes. The sight of the ecstatic Kirio towards the trapped fearful prisoners causes Atori to change his mind; witnessing a wonderful example of a wicked demon who's gone through Return to Origin.Meanwhile, Iruma and company are now atop a parade float set up by Ronove's father, Rosevelt, and are being cheered at by the park visitors. Rosevelt remains happy and grateful to Iruma and his friends for saving his Walter Park, and helps hype up the crowd alongside his son to make sure that the crowd celebrates the heroes who defended them from the demonic beasts. Catching sight of the celebration from a nearby alleyway is Kirio, who's left amazed that it was Iruma who once more foiled his plan, and believes that this is destiny. Kirio is then contacted by Baal, who despite still wanting the park destroyed orders them to retreat due to the police arriving. Baal is glad to have Kirio back at his side since the latter's warped mind will be necessary for their chaotic ambition, which Kirio agrees with. Before leaving, Kirio takes one last look towards Iruma believing that they will surely meet again since the boy is his destined enemy. Shiida also takes one last look towards Iruma before leaving with the others.
Iruma takes a look towards the dark alley where Kirio and company were believing to have noticed something. However, he's interrupted by Opera giving him back his lost backpack. Iruma finds the note left behind by Sullivan where Iruma promised to have fun with everyone in the park. He then looks towards his friends and teachers. Seeing them all happy and enjoying themselves despite the crisis that happened leaves Iruma believing that he kept his promise.
Chapter 88: With a Sparkle
Sullivan arrives at Walter Park having heard about the crisis, and is relieved to see that Iruma and company are all okay. Afterwards, Rosevelt continues to reward his park's saviors by allowing them to stay within his luxurious Rosevelt Hotel that sits atop a floating rock high above Walter Park. During their stay, Sullivan is glad to hear that Iruma enjoyed his time at the park, which he officially assigns Opera, Kalego, and Shichiro as his permanent bodyguards. Meanwhile, Kalego and Shichiro discuss the culprit behind the attack on the park. They confirm that the attackers were members of the park staff, but no one knows about the Six Fingers appearing due to Wett using a magic that erased the memories of those the Fingers interacted with. Thus, leaving them at a dead end.Kalego and Shichiro return to their hotel room only to find Jazz, Lied, Goemon and Kamui enjoying themselves playing around the hotel, much to Kalego's annoyance that his park group is still bugging him. Meanwhile, Clara, Ameri, Elizabetta and Kerori continue their all-girls fun having been rewarded to pick out clothes for themselves within the hotel's clothes shop. Later on, Rosevelt provides Iruma and company with a massive dinner buffet. Iruma goes off on his own to the hotel balcony to think about things while looking down at the park below him, which Ameri notices and follows him. However, she starts to blush when she realizes that this is a private romantic event that popped up in "First Love Memories." Ameri approaches Iruma in a hotel dress she picked out, which Iruma compliments that it suits her.
Iruma explains to Ameri that he's thought about their talk about ideals and ambitions, and that he's decided that his ideal is indeed to go about having fun with everyone. Thus, making that his ambition. However, he knows that he needs to continue changing in order to achieve his ambition of protecting said ideal, which he confidently asks Ameri to watch him. The sight of a confident Iruma impresses Ameri into believing that he's continued to become stronger. Ameri decides to follow one of her own ideals and is about to ask Iruma out on a date between just the two of them, but is interrupted by Azz and Clara wanting Iruma to return to the dinner buffet. Before going back, Iruma catches Ameri off-guard by finishing what she began to say, and asks if they can go somewhere just the two of them, which excites her to the point of knocking her out.
Following dinner, Iruma returns to his hotel room to get some sleep only to see on the television that Sullivan and Rosevelt are announcing on the news of how Iruma and his friends are the heroes who saved Walter Park. Thus, leaving Iruma fearing for the worst that he's been made more famous despite his desire to stay out of the limelight.
