Mary is a 7th generation monster hunter, the only problem is that there are no more monsters or supernatural beings around to hunt. Outcasted from her schoolmates and family, Mary decides to prove to everyone just how good of a monster hunter she is.... But first she has to find some supernatural beings to do so. Mary's plan is slowly going to shit when one day she comes across an old family spell to summon magical creatures. But to Mary's dismay nothing seemed to work...or so she thought. Slowly one by one supernatural beings started showing up around Mary and now she has to teach them how to get through high school without being caught.
