Yohko Mano is introduced. Yohko goes about her daily life; day dreaming about a cute guy named Hideki. Yohko learns that her family has a long history of being devil hunters. But this time the demons decide to take out the next devil hunter before she can fight back. After a failed attempt to take Yohko's virginity (so that she can't become a devil hunter), the demons decide to use Hideki as bait. Yohko must become the 108th devil hunter and rescue the man of her dreams.
