Tatsuya Serizawa
芹沢達也
One of Ren's best friends. Always butting heads with Kanon Suzuhara, Tatsuya is always trying to keep Ren to himself in order to help him pursue more manly things in life. Though outwardly he appears to like Ren in a romantic way (because of the way he acts around him), he's really only concerned that Ren will be too feminine if he hangs around Kanon.
