Kinji Enters the Yokai Labyrinth!

Nagi is trying to develop new Ninjutsu techniques using documents in the Dojo library when he comes across the words “Yokai Sword Urasame” which appears to be a sword that feeds on spirit power and decides to look into it further, checking even the restricted scroll of “Yokai Swords”. At the same time, Kinji starts getting the feeling that something's wrong with his body, realizing that the spirit power that Kyuemon used on him is turning him into a Yokai!
