Kagerou

Kage Houshi, whose real name is Kagerou, is the first antagonist of the series. She possesses the madougu Eikai Kyoku ("Shadow Ball"), which allows her to teleport through shadows, show people the past, and perform acts of scrying. Later in the series she is also seen wielding a Shikigami (hair) and the madogu Hokishin.

She performed a technique called Jikuuryuuri (a technique which allows the user to travel or send another person to a different time) to save the infant Recca from being killed along with the rest of the Hokage clan. The technique, however curses the user with immortality. Her curse is finally removed after the fight with Rasen.

She is later revealed to be Recca's mother.
