Build Divers As the BUILD DiVERS prepare for their training match in the form of an updated Lotus Challenge, Hiroto briefly reunites with his former Avalon forcemates and they are formally introduced to the original Build Divers. The BUILD DiVERS proceed with the challenge with the additional condition that they will instantly fail if even one of them is shot down. During the Lotus Challenge, the BUILD DiVERS face off against not only Riku and the Build Divers, but also Rommel and his 7th Panzer Division, Ogre and Hyakki, and Kyouya and Avalon. Meanwhile, Mizuki watches Kazami's records of the BUILD DiVERS' exploits on Eldora, and comes to understand Masaki's plight a little more. She convinces the hospital to release Masaki early and gives him her blessing to help the BUILD DiVERS on the condition he return home safely. Back in GBN, on their 40th try, the BUILD DiVERS are finally able to break through the opposition and beat the Lotus Challenge after unlocking their team's Special Move, with everyone surprised at seeing something they haven't seen since the First Coalition of Volunteers Battle. The participants celebrate afterwards, with it being implied that Rommel is actually Captain Zeon. May, knowing deep down Hiroto is still not quite comfortable, arranges for Hiroto to meet Riku and Sarah privately, having just told the Build Divers about Eve and what happened behind the scenes and the true nature of how more EL-Divers got discovered, with Kyoya bringing logs and old photos since she knows that Hiroto knows they weren't deleted. Riku desperately apologizes to Hiroto, but Hiroto insists that he holds no grudge against Riku and his team, also telling them it was Eve's wish for Sarah's survival, to ensure that they would both be happy, and help GBN flourish. Hiroto thanks them for helping him keep his promise, and both Riku and Sarah accept him as a part of the Build Divers family. The two aces of both teams promise to continue having Gunpla battles and rise back up together by trading each other's wishes as Hiroto gains closure. After returning to the real world, Hiroto has a talk with Hinata about what transpired. Hinata implies that she intends to play GBN even if there is not much for her to do and the two promise to continue to support each other in their own ways. Hiroto is pumped to return to Eldora for the final battle and Hinata for an important bow ritual.
