The value-priced complete Blu-ray of school, adapted from Maya Miyazaki's original work in collaboration with animator Megumi Ishihara. In an isolated rural village, a crumbling two-story school has only four adult students. Kota Kamisaki is the sole man, surrounded by his childhood friends Ai, Rui, and Hitomi—until their greatest rival appears. Their boyish, slender teacher is secretly a shameless sex addict who treats Kota like her toy. Once his childhood friends discover what is happening, each rushes to seduce him wherever she can. Will Kota fall under his teacher's mature charms, and what will become of his friendships? Quiet school life erupts into a heated battle for his love.
