もみじ

A fairy-like being that lives in the massage parlor, having been a good friend to the previous owner. A strange-looking cat, he’s here to guide the protagonist from a fumbling beginner to a dexterous master. He passes on the secret technique, Mystic Art: Pleasure Rush along with the Ultimate: Celestial Wolf Fang Gloves, an item meant to improve its efficacy, to Atsushi.
