Ryo is a one track type of person, he's very bullheaded and compassionate.
Ryo is also very family oriented, he is very skilled at martial arts and can beat multiple men at once.
Even with these endearing traits he is an extremely boring person so much so that he almost seems like a robot.
Not to mention he is the worst romantic partner of all time. Ryo has no passion when it comes to love infact he goes out of the way to avoid it.
(Ryo is always looking for people who know about Chinese people)
