Mugetsu - Touhou Wiki - Characters, games, locations, and more

Mugetsu (夢月) is the first Extra Stage boss of Lotus Land Story and possibly the creator of a mysterious dream world. She appears to be dressed as a maid of some sort, but according to the music comments of her theme "Illusion of a Maid ~ Icemilk Magic" in Lotus Land Story, she is probably not a maid.
