Heartwarming / Gundam Build Divers

Episode 1

• When the boys were first introduced to GBN, Magee greeted them nicely and guides them in their Gunpla piloting. His Papa Wolf (or Mama Bear depending on how he addressed himself) moments shown twice when he chastise a black market dealer for picking on the boys and orders them to retreat when Do-ji were out to get their points. Heck, he even offers to avenge their deception and is more concerned if all these things ruined their experience in GBN.
• Although Riku agrees to retreat, Sarah tells him that his Gunpla is not content on giving up and he agrees to continue the fight, pulling off a counterattack using Yukki's Beam Saber by piercing the Zedas' cockpit.
• Even if everything happened within their first day of diving, neither of them shows any sense of discomfort and is excited on their first experience as a diver.

Episode 2

• The cameo of Patrick Colasour this time has him tearfully celebrating a victory with his force, without having its AEU Enact losing a head.
• Sarah defending Riku's damaged 00 Diver from Ogre GN-X, who was about to finish him and Ogre in turn complies, leaving them peacefully with Do-ji.

Episode 3

• Kyoya and his rival Rommel shares a peaceful moment at a bar after their recent match. Although being rival players at best, both are equally concerned with the rise of Mass Divers threatening GBN and Rommel offering assistance to Kyoya if he ever needed one.
  • Although its amusing to see Kyoya rubbing into Rommel's paws, the latter seems not to be bothered by it, only asking when would he stop.
• Momoka starting to show interest on GBN and decided to dive into it as well using a guest Diver Gear. Although she was reduced to a pink Haro, Magee gives her a welcoming gift by giving her a set of cat ears.
• Kyoya disguises himself as newcomer to GBN and is perfectly happy to go on beginner-rank missions with newbies like Riku and Yukio, looking to prevent them from being exploited by cheaters. Granted, that he was hunting Mass-Divers in his disguise but defends them anyway when Devil Gundam appears. And after the mission is over, he apologizes for lying and even adds them to his friends list.
• During the period of recharging their Gunplas, Kyoya comforts Riku on his earlier Heroic BSoD.
  • At that same time, Momoka took advantage of her Haro form and plays with Sarah at the background.

Episode 4

• Initially coaching both of our protagonists out of his weakness for girls, Tigerwolf slowly shows acknowledgement after witnessing Riku and Yukki's determination. He even protects them from a rival Diver and acknowledges their guts for not running away from the battle.

Episode 5

• During Shahryar's King Incognito mode to uncover his impostor, he has no problems teaching Riku and Yukki the elements of building Gunpla, such as the need of love. He also smiles when Riku acknowledges how the fake Shahryar's Gunpla lacks a true quality when nobody dares to question it.
• When the fake Shahryar's assistant tries to grab Riku, Ayame dashes in and unmasks their trickery, saving the boy at the expense of being scolded by her master. Her excuse? She was only saving their target (Riku).
• During Ayame's fake kidnapping, Shahryar lends them his mini Ptolemaios as a transportation before he gets there and personally defeated his impostor. Not only he lends them his creation, he also participated in their rescue mission and directly attacks a pair of Mass-Divers.

Episode 6

• Koichi's reaction to realizing that he's been denying his own enjoyment of something he loves and locking himself away out of depression from losing his Gunpla Duel friends is pretty heartbreaking, but seeing him realize that he can once again make friends doing something he loves is pretty uplifting. It's a surprisingly realistic and honest moment when he breaks into tears while listening in on Riku, Momoka, and Yukki fixing his old, damaged models.

Episode 7

• Kyoya sending an encouragement letter to Riku before his match.
• While he is shocked that his rookies lose to Build Divers, Rommel eventually acknowledges the latter team's strength and promises to hold another match with them another time.
  • Just like before, Rommel lacks discomfort and allows both Sarah and Momoka to pet him. Granted, that it happens to him all the time.
• The Build Divers decided to pick a flower necklace for Sarah as their winning prize.

Episode 9

• Do-ji might've besmirched the Hyakki's reputation for fighting fair (that is, without the use of Break Decals) but even his rough and tumble teammates understand why he does what he did. Rose is the first to comfort him, and even the taciturn Oboro smiles in agreement when she points out that they acknowledge him as part of their team.

Episode 10

• This episode highlights both the efforts of Kyoya and Rommel trying their best to uncover the Mass-Divers' base of operations when the administrations of GBN were seemingly hopeless. The Game Master even played a pivotal role by permitting all members of Coalition of Volunteers to enter the Beginner's Server while sealing the entrance shut.
• As Hyakki went on a self-imposed exile to atone for the previous episode, Ogre instead recommended Build Divers as their replacement to Kyoya's newly formed coalition. Ogre's acknowledgement of Riku as his Worthy Opponent is implied to be in a friendly terms, not unlike Kyoya and Rommel's relationship.
• The Patrick Colasour-like avatar is once again given luck when not only he meets Rommel in excitement, he was also trusted by Kyoya to join the Coalition of Volunteers. Whether Patrick still standing triumph or not in the Beginner's Server is another story.
• The fact that all Forces that were invited by Kyoya agree to join him is a Heartwarming Moment. All of them shared the mutual goal to protect the GBN and stand for their fallen comrades against these cheaters.

Episode 11

• Riku and Sarah telling Ayame under no uncertain terms that they were going to abandon her. Despite betraying them, they understood her reasons and are more than willing to help bear her sins no matter what.

Episode 13

• The lengths Riku's friends go to find and potentially save him when he suddenly goes off the grid for his duel with Tsukasa show how much they've become True Companions.
• Ayame's realization that she isn't alone when Kozy and Su revealed they got back their old Gunpla, then finding out Riku got it back for her. Also, who could ever forget that smile◊?

Episode 14

• Ayame, or rather, Aya Fujisawa, comes to thank Riku and the others in person for getting her friends' Gunpla back.
• A small one (depending on how one sees it that is). Destiny Gundam, of all Mobile Suits in Gundam history, being used as one of the bases to the creation of the 00 Sky. Destiny Gundam is one of the few that had always looked down on as a "flawed Gundam" (even after its performance in Gundam Build Fighters Try), making the revelations of its Wings of Light combined with the 00 Gundam's Twin Drives a pleasant surprise that soon culminated into the very thing that allows Build Divers to clear the seemingly impossible Lotus Challenge in Episode 15.

Episode 15

• Ayame looking cheerful than prior to her meeting Riku and the cast. That is all.
• After what felt like a failed attempt to destroy to core of the La Vie En Crab/Lotus Fortress, as further exhibited by Ayame and Yuki's inability to chase and destroy the descending core on time due to the speed of said descent, Riku's refusal to leave their efforts in vain (Alongside Sarah's declaration that the 00 Sky could still fight) soon lead to the first time activation of the "Trans Am Infity" mode, allowing Team Build Divers to clear the unbeatable quest for good.
  Riku: I won't give up...No way I'm giving up!
  Sarah: The 00 Sky can still fight!
  Riku: I'm not letting everyone's efforts become useless, I'll definitely reach it no matter what! The power of 00's Trans Am and Destiny's Wings of Light...Trans-Am Infinity!

Episode 16

• Ayame being reunited with her rebuilt old team. Even more, after the match, Magee gives them the suggestion of forming a Build Alliance, essentially allowing both groups to work in a friendly capacity.

Episode 18

• A brief scene from the end of the 4th match of Ryukosai reveals a member of Toraburyu implicitly tearing joyfully at his hard-earned victory while Daniel of Desperado (the pilot of a customised Tequila Gundam who had previously appeared back in Episode 4 with the intent of earning points from challenging Toraburyu) could be seen shaking hands with said member and comforting him, having taken his lost unexpectedly well.
  • The mere fact that Toraburyu invited the Diver that had personally attacked their Force for Diver/Rank Points into their annual friendly One-on-One Matching event speaks volumes of their possible respect of talented Divers.
• Upon the conclusion of Tigerwolf and Riku's battle, Rommel applauded at the performance of the fight and willfully broke the chip containing the recording of the aforementioned match, despite clearly intending to make use of the recording so that 7th Panzer Division could prepare properly against either Tigerwolf or Riku one day.

Episode 19

• During the race, Sarah hears a cry for help off the race path. She and Nanase go off the path and find a little SD Zakurello-like creature trapped under some rock. Nanase moves the rocks off of it and is rewarded with several rare items.
• The racers reach the final checkpoint of the marathon, which was supposed to be a race using provided motorcycles. But a bug-caused lighting strike destroyed them. Rose figures they should just use their own Mobile Suits to finish, but Nanase suddenly gets the urge to make a machine for her own. What she does have, however, are a bunch of destroyed motorcyle parts and a legendary item she got from helping that Zakurello that can put them together into something useful. All the other racers decide to help her gather the parts and make her first machine.
• The racers all managed to hit the finish line at the exact same time. But since they didn't use the provided machines, they were all technically disqualified. Until the chairman of the company sponsoring the event said Screw the Rules, I Make Them!, and had them all declared winners.
• Nanase has gotten into GBN now, and wants to build her own Gunpla. One of the base models she's going to use is a Zakurello, presumably for the little guy who gave her the item that ultimately allowed her to finish the race. It's rare that the Zakurello, hands down one of the ugliest machines in Gundam history, has ever been given such genuine love.

Episode 22

• Despite the overwhelming odds in this action, it's heartwarming to see Magee, Tigerwolf and Chat Noir Neo are willing to aid Riku and his friends in their hour of need.
• The sight of Tigerwolf holding the children of Chat Noir Neo on his arms is both silly and heartwarming. He's like a big puppy to them.
• When Riku challenges the Coalition of Volunteers in capture the flag challenge, we can see that the Lotus team also giving the Build Divers their support by using their Lavi-En-Rose base as a starter. Their Force leader even put his faith on Riku, saying how he believes that the boy can make the impossible, possible due to their previous encounter.

Episode 24

• As they were on the verge of defeat, Force Hyakki delivers a Big Damn Heroes moment. Although they only act under Orga's orders (who refers Riku as a Worthy Opponent), Do-ji is shown genuinely helping them, saving Yukki and asked the former's well-being. Its pretty much cements his Character Development from a Fat Bastard to a Fat Best Friend (or at least, a Friendly Rivalry).
  • After defeating AGE-II Magnum SV, 00 Sky races towards Team Avalon's Force Nest and Ogre, of all people shouts:
    Go, BUILD DIVERS!
  • Before being rescued, Ayame and Koichi even deserved credits for remembering how Sarah bring them out of their miseries.
• Riku's rescue and reunion of Sarah is both tear jerking and heartwarming, even the Game Master decided to acknowledge the Build Divers as winners themselves.
  • And then there's Mol enlarging itself to catch both Sarah and Riku for a safe landing.
• Rommel apologizes to his subordinate Kurt for losing, since it is heavily implied Kurt's real life body is crippled and he can only enjoy full range of movement in GBN. Kurt thanks Rommel for care so much about him but points out that even if GBN is destroyed, they can always rebuild it since they are all builders at heart.

Episode 25

• Everyone comes out to help the Build Divers in defeating Raid Bosses. All includes members of Coalition (some of them even openly apologize to Riku), Hyakki, Chat Noir, Archangels and even main characters in the novels and manga of Build Divers side stories. Heck, there's Patrick Colasour being one of the leads and proclaims his declaration of protection.
• Sarah successfully materialized into a Mobile Doll in real life. The process of removing her data was almost failing had her not regaining her memories of Build Divers.
• Kyoya (Kyoya Kusugi), Tigerwolf (Kotaro Ogami), Shahry (Ruck Arge), and Magee all come out to meet the Build Divers team and Sarah in person.
• In one of the scene outside, there's one that wrote; "Thank you, Tomino".
