For 10 years, Wizard Iori and Werewolf Hanao cohabited to discover a cure for the curse that turned creatures into beasts at a full moon. They eventually uncovered the connection between transformation and sexual arousal. To help Hanao control his urges, Iori instructed him on self-pleasure. However, Hanao began to develop strong romantic feelings towards Iori. Upon recognizing Hanao's infatuation, Iori cast a spell to erase Hanao's emotions. "As a non-human, you must not engage in a relationship with a human to live among them."
