4 new students arrive at the well known Yokai academy. They are a strange bunch, yes, and they seem to have known each other for quite a while. But, as Tsukune and Moka dig up their past and find out that these monsters went through hell to get there, they try to help them. One of these monsters, though, have their own goal in mind. And sacrifices must be made.

The gang meets a new monster. OC is based on the slender man.
