Chrome appears in the battlefield, joining the battle as Reborn's representative. This shocks and worries Tsuna; he questions her condition as her organs has disappeared. Reborn tells Verde to give Fran's equipment to Chrome so she can make a combo attack with Mukuro. Verde refuses at first, but after Reborn pleads, he rushes to Chrome to hand over the glove. At this time, they realize that the Vindice who were running amok just a while ago suddenly stopped their attacks.
At Vindice Prison, Jaeger asks Bermuda why he suddenly ordered Jack and the other Vindice to stop attacking. Bermuda replies that there's one person who keeps defying his expectation, and now he probably would understand. He orders them to wait three minutes and if Chrome didn't do anything, they'd put an end to the fight. Back at the battlefield, Tsuna asks why Mukuro isn't helping Chrome with her illusionary organs and gets angry when Mukuro seems careless about it. Reborn tells Tsuna to calm down and says that it's not Mukuro's fault, but rather Chrome's problem. He reveals that Chrome is rejecting Mukuro's illusion and explains that because Mukuro and Chrome no longer share one body and destiny, Chrome's feelings began to change. This made her want to be accepted as a single person. However, at the same time, some part of her still wanted Mukuro to continue providing her with illusionary organs since so far she's lived that way. This made her struggle with her own dilemma, worsening both her feelings and body. Reborn comments that he could understand if Mukuro wanted to keep a distance between them since she's confused, which is why he sent her to Namimori.
Mukuro reveals that he wanted Chrome to become a full-fledged soldier because he discovered her talent as a warrior, but she kept refusing everything and became weak. Chrome, wanting to protect Mukuro and those who are important to her, unleashes a powerful Flame, recreating her illusionary organs in the process. With her energy regained and her resolve found, Chrome combines her strongest illusion with Mukuro's and creates Genju Mugaia.
