Touhou
The games are set in Gensokyo, a place sealed from the outside world where mostly humans and youkai live. Youkai are creatures from Japanese folklore that are represented as people in the game as female characters most of the time. Reimu Hakurei, the shrine maiden of the Hakurei Shrine and the main character of the series, is often involved in settling supernatural incidents in and around Gensokyo. Other main characters include Marisa Kirisame, a witch, Sakuya Izayoi, a maid, Reisen Udongein Inaba, a moon rabbit, and Sanae Kochiya, a shrine maiden at the competing Moriya Shrine.
