Yuna Miyama

宮間 夕菜

Yuna, the typical harem anime "housewife," transfers to Aoi Academy to become Kazuki's wife and even first introduced herself as "Yuna Shikimori" to the rest of Kazuki's class. Yuna is the only one who actually cares for Kazuki from the very beginning instead of just being interested in his genes. As the series progresses, Yuna becomes extremely possessive of Kazuki, and becomes very jealous when other girls show any kind of interests in him.
