Shadow Oni

The Shadow Oni was an oni of the Shadowlands, a monster which needed a living host, a mind to fill with hubris and vice. In 1117 the Crab Clan sent a party to the Shadowlands to get rid off it, but the oni possessed the party's leader, Hida Kiyosue. Kuni Ritsuko killed its host, after she realized her commander had been possessed, and the Shadow Oni just passed onto the Shugenja. She noticed her presence, ordering the scouting team to chain her to a nearby tree, and left her alone, waiting death, forcing the Shadow Oni to die, as it would not find another suitable host in the vicinity.
