Due to the enormous amount of power Yorihime wields, she along with her sister are popular Mary Sue candidates within the the Touhou Project community.
One particularly infamous example of Yorihime's image following this trend is her depiction in Koishi Komeiji's Heart Throbbing Adventure.
Due to their lack of appearances, combined with ZUN's comment of "their power being too strong to be shown in a game," Fans tend to call her and Watatsuki no Toyohime "the next Mima's."
