Shinki

Shinki is the final boss of Mystic Square, the last game in the PC-98 era of the Touhou Project series. She is also the creator and ruler of Makai, a demon world, and refers to herself as a "god". Despite her immense power, Shinki exhibits a somewhat childish personality. In Mystic Square, she battles Reimu Hakurei and other heroines who investigate the chaos caused by Makai residents who organized unauthorized tours to Gensokyo. In fanworks, Shinki is often depicted as the mother figure of the residents of Makai, such as Alice Margatroid, with vast power and a multifaceted appearance. Her silver hair and signature side ponytail are iconic features, and she reveals six black wings during combat. Although she has not appeared in Windows era games, Shinki remains a popular character within the Touhou fandom, with many fan-made works and admirers.
