An aimless gamer and his two friends find themselves in a parallel Tokyo, where they're forced to compete in a series of sadistic games to survive.

Set in the 19th century, "Moeyo Ken" follows the life of Toshizo Hijikata. He was the vice-commander of the Shinsengumi and fought against the Meiji Restoration.

Before he was a protector, Kenshin was a fearsome assassin known as Battosai. But when he meets the gentle Tomoe Yukishiro, his story begins to change.
