A ghost story that Tezuka never got to finish, animated as his final message. One episode exists because he ran out of time. You're watching a dead man's last thought about what happens when you sell your soul, and the weight of that incompleteness is the point, not a flaw.

Neo Faust is a one-episode supernatural special tied to Osamu Tezuka, who long wanted to bring the story to animation but saw the project shelved again and again. This version was meant to finally realize that ambition, yet Tezuka fell ill and died while still drafting its synopsis, leaving it among his unfinished works. The special was broadcast as part of an NHK program built around Tezuka and his message for the end of the century.
