One of Momoko's trio of friends, a fairly high-class Proper Lady, a well-rounded academic, and the most outwardly feminine of the three. This by no means makes her naive, however, and in fact she's capable of being the most manipulative and terrifying when angry - but, in most cases, she's a loyal friend and dedicated to her loved ones. In battle, she joins Peach as Angel Lily, and on top of fighting prowess with the Saint Lip Liner is the most empathic of the three.

She is eventually revealed to be the reincarnation of the Angel Lily of the past, who fought in the first war against the demons and had her soul sent down to Earth after her death. A good part of the latter part of the series builds up a relationship between herself and Mysterious Protector Limone, as it pertains to Yuri's past life; to what degree differs between the manga and the anime.
