Things are settling down with the two battery girls, but Hosomichi's regret is catching up to him. He believes what they fight for may not be worth the damage they cause. Meanwhile, a strange box appears in their room...

Akatsuki believes he has seen the true face of Arahabaki and finally decides to end things once and for all. Arahabaki must decide their plan of action before the True Army launches their attack. However, Hosomichi continues to hold doubts.

As the situation gets dire, Munakata convinces Hosomichi to betray Arahabaki and steal the Garanndoll. Hosomichi leaves behind three angry battery girls. Just in case, Tanaka and the rest of Arahabaki prepare a new battery for their pilot's return.
