Protagonist Yui Tsuchimikado has always had a sense for the supernatural that set her apart from others.
One day, she accepts an invitation to partake in an occult club ritual that will free her from this isolating power.
However, the ritual was actually to summon a demon. It promptly curses her, leaving her no choice but
to exterminate a series of reawakened horny spirits if she wants to get out from under it.
