Kiss x Sis

Keita Suminoe’s life changes when his father remarries, bringing not only a new mother but also twin older sisters into his home. Having grown up together since kindergarten, the three share an unusually close bond—one that gradually shifts into romantic and decidedly risqué territory. Ako, a warm and composed former student council president, contrasts with Riko, an athletic and cool-headed ex–disciplinary committee president, yet both set their sights on Keita.

Now in his final year of middle school, Keita earns a sports recommendation to a high school different from theirs, leaving the twins determined to keep him close. He relents to their pleas, only to find himself juggling exam prep while fending off their increasingly forward attention. With their parents’ approval, Ako and Riko openly compete to become Keita’s future wife, and he struggles to keep the relationship from crossing lines he’s not ready to accept.
