Witch Watch

Morihito Otogi is an ogre with human form, a result of his witch mother marrying her familiar. Nico Wakatsuki, his childhood friend and a young witch, returns home after training in the Witches' Holy Land with the intention of claiming Morihito as her familiar. This arrangement is unusual, as most witches choose animals for their familiars. Morihito initially resists the idea, but eventually agrees to live with Nico, allowing her to blend in with human society.
