Nope! The game is *inspired* by a Chinese folktale.
Mizuchi's story is set in an “ancient Asia fantasy land” where each character reflects a different region, with designs and names based on authentic cultures and real places (China/Japan/etc). However, the story is not set in any specific place, location names are made up as well. It's inspiration! (Ie: LotR's Middle Earth, Game of Thrones, inspired by real things/places but not actually real or set in a 'real life place').
