Mitsuki is a a high school student but people mistake her to be an elementary school student. With the help of Atsuki she is transformed into a beautiful highschool girl called "May" (the name given to her by Kyo). She also is very very indecisive and sort of a crybaby-ish person. She gets her first kiss from Atsuki when he is putting on her makeup. [Source: http://en.wikipedia.org]
