Himura Kenshin thinks that Battousai is forever gone, locked away in his fragile mind. This bloodthirsty side of himself is far from it. "To never spill a drop of blood again" is the oath he made to himself when he put down his sword and became a wanderer. However, that promise would soon be broken, along with his "nearly harmless" reverse-blade sword. Kenshin was part of something bigger when he was a murderer. His old colleagues are catching up with him, and danger surrounds them. Kaoru, Sanosuke, Yahiko, and Megumi can try, but they may not succeed in destroying the Battousai and get Kenshin back to himself before his past swallows him again. It's something Kenshin may not even be able to do.
