makai (touhou)
The plane of demons seen in Touhou Mystic Square, ruled by the devil-goddess Shinki. Sara, Luize, Yuki, Mai, and Shinki's bodyguard/maid Yumeko are known residents. Alice Margatroid originally lived here with her mother figure Shinki, but has since moved to the Forest of Magic in Gensokyo. Hijiri Byakuren was formerly imprisoned here. And many fans speculate that Koakuma is a former resident.
