Yoshino is 17 years old and about 176 cm tall. He has rather long brown hair, which he combs to the right side so that they cover the entire right side of his face, as evil classmates usually put out cigarettes on his forehead on that side of his face. He has brown eyes and a rather thin build. He is not particularly talkative and withdrawn because of classmates at school and the stress there. The only dear person is his mother.
