Yohko Mono is a regular girl making her way through high school--until she learns that she is the 108th successor to a line of warriors charged with defending the earth against demons. Eventually she must fight her ultimate battle against the demon who started it all.
Yohko must keep her virginity intact until she becomes a full fledged mystic ninja, or else the power will skip another generation as it did with her mother. Yeah ecchi humor and sex crazed demons make for an interesting show.
