Asagi's classmates don’t seem concerned when her friend Satake suddenly dies in a strange way: they just continue their conversations about food and karaoke. While Asagi struggles with her loss, everything around her becomes increasingly absurd. A promising, idiosyncratic psychological horror debut with a generous dollop of dark humour and an eerie atmosphere.

An unknown person has started a mysterious "ceremony." It is something that already exists before meaning is even born. Once begun, it cannot be stopped. Is it a blessing, or a ritual of farewell? And where does the answer lie? The film portrays the story of one such "ceremony" that exists somewhere in the world.

A group of friends gather at a lakeside for a party. Mao stands alone, observing as Kenta flies a drone over the lake. He suddenly drowns but returns, exhausted. The others party in the cottage, unconcerned. At night, Kenta and others start obsessively drinking water, losing their will.
