Shiina Ren

He is a beautiful boy who transferred to Sei and Fuuta's class. He loves chemistry, and he transferred to this school because he admires Gaku, who is in the university club, but he is disappointed to find out that the chemistry club does not exist.

He is the most beautiful boy in the school, but he does not make a good impression on those around him because of his cold, inaccessible atmosphere. However, once he has gotten to know a person, he is very open and honest with them.

He is especially obedient to Gaku, whom he admires.
