本能寺司

Haruomi's classmate, they eventually become good friends. He's not smart, but he's good at sports. Even though he is good-looking, Tsukasa isn't popular with girls because of his cowardly and weak, "hetare" personality. Despite that fact, he loves girls and really wishes to be popular with them. Convinced that Haruomi has grasped his weakness, Tsukasa feels as though he is outclassed by him. Even so, he greatly adores Haruomi. His favourite phrase is "I'm your best friend, riiiight?" When Haruomi is down, Tsukasa shows his kind side when he tries to cheer him up. Very self-conscious about his height, he wears "secret shoes" to give himself a 10cm boost. He's also afraid of becoming bald, since his father is so. His behaviour is puppy-like, so he frequently (and jokingly) gets called "Pochi" and "Shiro" (common Japanese dog names) by his peers. The events of "Doki Doki Full Throttle" suggests that he may be bisexual or homosexual. [Based on the official website's character profile.]
