Rin Itoshi. Quiet and rarely smiles. Has few friends because he is not good at communicating with other people. More precisely lazy to socialize. Typical of people who don't want to make a topic first. If no one asks him to be friends he probably won't have any friends because he feels he doesn't need friends and isn't interested in asking other people to be friends with him. Even so, he still has a handful of people who sincerely want to be friends with him.
