Seiken Gakuin No Maken Tsukai character.
Riselia Ray Crystalia's childhood friend and personal Maid, Regina is a buxom girl who spends most of her free time trying to elicit a reaction from Leonis who deeply dislikes it (especially considering that this is the first time since forever that Leonis had a human body). She is in actuality the (former) Fourth Princess of the Integrated Empire, Regina Ray O'ltriese, however, due to being born under a superstitious star, she was removed from the family and replaced by her younger sister, Altiria Ray O'ltriese.
