Makoto Shishio, a former assassin like Kenshin, was betrayed, set on fire and left for dead. He survived, and is now in Kyoto, plotting with his gathered warriors to overthrow the new government. Against Kaoru's wishes, Kenshin reluctantly agrees to go to Kyoto and help keep his country from falling back into civil war.

Shishio sets sail in his ironclad ship to bring down the government. In order to stop him, Kenshin trains with his old master to learn his final technique.

It follows a young man who dreams of becoming a general and Ying Zheng, whose goal is unification.
