Miyamura is often mistaken for an otaku because of his shady character at school. The truth behind his long hair is to hide his piercings, and he has a lot of tattoos. This is a secret that only Hori and Ishikawa know. He wears only his winter school outfits year long at school to hide his tattoos.
Izumi is a very thoughtful kid. He is a person who looks weak but is very strong and Hori comes to greatly depend on him.
