Rurouni Kenshin: Meiji Kenkaku Romantan

Synopsis

Sanosuke uses the Futae no Kiwami attack Anji taught him to stop gattling gun bullets from hitting him. He then throws the bombs Tsunan Tsukioka gave him before he left Tokyo right onto the Purgatory, damaging the engine and leaving a hole in the ship. The Purgatory eventually sinks, but not until Kenshin, Sanosuke, and Saito get off safely. Shishio issues a challenge; Kenshin can only meet him at his base and get to him by completing one-on-one fights. Kyoto is spared from the Kyoto Grand Fire as well, thanks to intervention by the Oniwabanshuu, now headed by Misao.
