Shiva, a small girl, lives in an empty village on the Outside, cared for by a tall, horned figure she calls Teacher. Their world is split between the Inside, where humans live, and the Outside, ruled by cursed beings whose touch is said to spread a blight. Forbidden to touch, the two keep a quiet routine and a gentle bond despite belonging to opposite realms. When Shiva slips away to look for her grandmother, the truth behind why she lives on the Outside begins to surface. This OVA adapts Nagabe's manga.
