Esaka Haruki

He is a member of the Intellectual and Cultural Studies Club. Although he looks young and cute, he is actually a boy.

He loves the main character, in a gender-neutral way, of course. The main character thinks it's like a dog's love for its master, and doesn't take it seriously.

He was originally the main character's chatting companion, and met him on a certain bulletin board. He always dresses up as a cute girl in the playground, but in school he hides it and acts as a normal male student.

However, because of his growing feelings for the main character, he decided to dress up in a female student uniform and join the “Intellectual and Cultural Studies Club."
