What do you mean we've run out of bananas?
A rather easy-going person, Ryou's default expression involves a big grin and a twinkle in his eyes. He likes to joke around a lot and in general likes to have a good time. That doesn't mean he's an idiot, however, thought he might like you to think so. It takes one responsible and intelligent person to run an Academy almost single handedly, after all, and look after all of his beloved, insane students.
Ryou's primary weapon is a bo staff. Laugh if you'd like- it holds just as many secret capabilities as the man who wields it.
