Ryoma is the Ultimate Tennis Pro from Danganropna V3. He is kind at heart, but is usually pessimistic and closed-off due to his past experiences. He is rather blunt and while he isn't the most happy with being alive- he does not let anyone treat him wrong. While he is quite short, he doesn't seem to mind, this talent only shows his skills as an athlete more. He is quite calm, and gives off a natural air of "coolness", but being a ex-convict makes him feel ashamed.
