is a female Japanese singer-songwriter from Tokyo, Japan. She is a Kunitachi College of Music graduate and also performs as an indie singer under the alias MAYUKO. Her music is produced by FlagShip and Lantis. Yuumao is a pseudonym she assumed in late 2002, used primarily when writing and composing songs for anime and games, such as Galaxy Angel and D.C. ~Da Capo~, and seiy?, such as Mai Nakahara and Ryoko Shintani. The name originated from "???" (yuumaou), which in turn was formed from "?????" (yasashii maou, lit. kind devil); the last "u" was dropped due to excessiveness. Her two singles, "Michishirube" and "Sweet Home Song" have both been ending themes for the anime Kashimashi and Asatte no Houkou respectively. Additionally, her song "Kimi no Tame ni Dekiru Koto" was played in episode 12 of Kashimashi and her song "Omoide ga Hoshikatta" was released on the Please Twins! vocal album
