Sui and Oga attempt to capture Makoto but find only an empty warehouse that explodes. Meanwhile, the siblings attempt to trace Tanpopo's Hazakura supply lines. Taiyo investigates a train as a possible supply line, unaware Makoto and Momo are hiding on board. When he drops his revolver, a silver haired woman named Shirai catches it through her window and returns it to him. Taiyo deduces the train engine has been modified to not produce smoke and yet there is a hallucinatory gas everywhere so he destroys the windows, revealing Makoto and Momo. Via GPS, Shion sees Taiyo confronting Momo so Futaba begins plans to catch the train. Shirai restrains Taiyo with her hair she can manipulate, revealing she is Makoto's greatest test subject. Makoto then demands they fight before he leaves with Momo. Shirai reveals Hazakura grants power but limits the user's lifespan to ten years, so she is going to die soon, and unless Taiyo stops her and the Hazakura loaded on the train, Tanpopo will consume everything, including Mutsumi. As her hair resists his electric bullets, Taiyo activates his revolver's second form, the electric katana Rain.
