Tatsumaki

A novelist, who is such a slump that he is actually thinking about selling his life and soul, meets a mysterious man and discusses the art of writing, and how things such as reality and existing conventions prevent him from writing. A strange series of events entangles a test knitter working under a harsh conditions, a frivolous man using online dating apps, and a woman carrying a corpse.
