Rumble Garanndoll

Hosomichi is taken to the base in Arahabaki after the events in Kabukicho. To pay off his debts, he's forced to become a Shark One pilot. For him, it's just another job and another paycheck. However, pleasing Rin can be harder than he expects.

Unable to awaken Rin's inspiration, Hosomichi causes her to fall unconscious when the Garanndoll closes. To bring her back, he enters her dreams to reconnect with her. In doing so, he realizes that he may need to reconnect with himself first.

Arahabaki brings in Yuki Aoba, the only survivor of an idol group named Rabbit Foot. She quickly accepts the chance to become a battery girl and gets Hosomichi to act as her manager. Hosomichi realizes there may be more to being a manager than he thought.

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...

Hosomichi meets the new battery girl, Misa Kuroki. She is a hacker, a gamer, and a cardboard box shut-in. Misa panics and locks herself in the recharging room. The members of Arahabaki must win a game against Misa in order to regain access.

Misa goes out and tries to save Hosomichi, who is currently stuck underground. Meanwhile, Arahabaki tries its best to stall for time against Yakumo's giant Garann, Banki. With both battery girls out of commission, Misa stands up to the challenge.

After a series of failures, Akatsuki decides to infiltrate Akihabara to truly understand the heart of his enemy. At the same time, Arahabaki begin the next stage of their plans in hopes to regain all that is confiscated in the former exhibition hall.

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.
