Miyama, Yuna

宮間夕菜

Yuna, the stereotypical harem anime "housewife," transfers to Aoi Academy to become Kazuki's wife, even introducing herself to the rest of his class as "Yuna Shikimori." From the start, Yuna is the only one who genuinely cares for Kazuki, rather than simply being interested in his genes. As the series progresses, Yuna becomes extremely possessive of Kazuki and grows very jealous whenever other girls show any interest in him.
