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