Kiss My Sister OVA

Suminoe Keita is a third-year junior high school boy who is about to take the high school entrance exam. When he was a child, his father remarried, and he became a sibling with his lovely twin sisters, Aka and Rika. Although there is no blood relationship, the three of them grew up together in harmony, but I don’t know when, Axiang and Rika seemed to have a love affair with Keita. Aka, who seems to be a serious person, but is actually a sultry type, and Rika, who is cold-spoken but very positive on the inside. Keita, who was approached by the two, fell into a dilemma in another sense that was not caused by studying for the exam.
