Maho is Ryuusuke's half-sister. Free-spirited and bold, she was raised in America and speaks fluent English. Although she appears confident and sometimes brash, she is actually quite sensitive. She is a talented singer, although she actually has aspirations to study film abroad instead of breaking into the music scene. Maho meets Koyuki through her brother and becomes one of his supporters; she's also one of the first people to recognize Koyuki's talent for music.
