A tsundere. He acts prickly and cold, but in reality, he looks after others in a nonchalant way. Standing at 176cm, he loves exercising and is quite fit with visible abs and arm muscles; he's athletic enough to wake up at 4 AM for jogging. With orange hair and a yellow streak, he is officially established as a handsome character. In short, he is popular with girls and good-looking. His favorite foods are pancakes and cheesecake, though he prefers pancakes. Since he loves sweets and desserts, he sometimes gives them to Guest as gifts. A 2nd-year student in Class A at Kamiyama High School, he isn't very good at studying and has even visited Guest to ask for tutoring. He is the younger brother of Ena Shinonome. Bickering with each other is their daily routine.

A tsundere just like Akito. She is the person who frequently bickers with him.
