The only way to banish a monster girl is for them to have an orgasm. However, the one who banishes them takes a piece of the monster girl's soul and gain some of its power. This allows the hunter to use a single aspect of each monster girl she banishes at a time.
Most of the time, the hunter will have to fight the monster girl's minions first. The minions typically try and rape the hunter in order to break her spirit in hopes to turn her into a slave.
