In 1972 a crackpot unit was sent to prison by a Yama for a crime they didn't commit. These nitwits promptly escaped from the Hakurei Shrine to the Gensokyo underground. Today, still wanted by the mikos, they survive as youkai of fortune. If you have a problem, if no one else can help, and if you can find them, maybe you can hire... The ⑨-Team.
