A third year in high school, Takumi Kijima is known as the "King of Normies." He has light brown hair and a slim but well-built physique. It is noted by Ao that he has well-toned muscles at the beach.

His advances toward Ao are always misinterpreted as perverted by her. Though she slowly starts to develop feelings for Takumi, she denies these feelings, saying that he is a pervert and a virgin.
