Kokoru (spelled "Cocoloo" in the subtitles of the ADV Films release) is a soft-spoken young woman who becomes Yucie's friend very early in the series. She is a fellow student at the Princess Academy , who wears tiny spectacles at the end of her nose, with her chief characteristics being self-effacing and gentle.

Cocoloo is so gentle that she is often ignored and talked-over by the much louder Yucie and Glenda, which causes Kokoru to lament that she "has no presence after all" .

However, Cocoloo is amazingly kind and encouraging towards her friends, which makes an impression on everyone who gets to know her. She, too, suffers from a curse that makes her look ten, even though she is seventeen.
