Introduction
Ryou is timid, but he hates being looked down and usually tries to swagger.
Ryou joined the Bursters because he supposed that he can get bigger when being a balloon. He found that Luck is timider than him so he calls Luck his servant and usually stays on Luck's head.
Ryou is not really interested in balloons. He is afraid of popping, but he tries to inflate to get bigger, and sometimes pops himself.
