Masaya Kimura

Onoe's childhood friend. He owns a restaurant that Onoe visits reguarly. He used to be a high school delinquent attending the same school as Onoe; referring to himself as the 'Loner' while Onoe was the 'Model Student'. After a fight with a couple of thugs, Onoe and Masayan become good friends, promising to be together forever. Now in the present he has become the go-to guy for Onoe to rant about his problems with Kaburagie even though Masayan is mostly apathetic to Onoe's relationship problems.
