Bosujima descends into Yuki's mind and finds a horror that no amount of fame can fix. The OVA never explains what he's really doing there, or whether he understands it either, you're left watching a man operate in darkness, diving deeper into someone else's broken psyche without a map. It's a fragment of a story that refuses to be complete, which is exactly what makes it work: a 50-minute hallucination that feels like you've stumbled into the middle of something far larger and stranger than you're equipped to understand.

Yuki Kano is a famous, wealthy pop star, but something is wrong with her: every so often she loses the ability to sing. Psycho divers use technology to enter a person's psyche and deal with mental problems directly, and Bosujima, known as one of the best, is hired to cure her episodes. Then he learns that an earlier diver died trying to help Yuki, and that her condition is strangely tied to a religious cult. He begins to doubt he will get out of her mind alive. The single OVA mixes action, horror and science fiction with psychological and supernatural elements.
