Tails
(Basic)
[[Noshiko Yukimura|Noshiko]]'s tails are represented in the physical world by small daggers called kaiken. In order to sacrifice a tail to summon an [[Oni]], she must break the blade. The older the tail, the more powerful the [[Oni]].
It is not clear at this time whether all kitsune will get kaiken, or how the blades come into existence.
