The Tanuki's Lover: Firefly Glow

The Tanuki are a mystical race of shape-shifting raccoon dogs that have lived alongside humans for centuries. In recent years, however, their number has been dwindling, causing them to seek out human mates in order to perpetuate their kind. Katsujiro is one such Tanuki, but with an overall poor batting average when it comes to getting intimate with the ladies... because when he gets turned on, his human-like facade melts away to reveal his true, monster-like form. Could anyone ever learn to love a beast like him?
