**A piece of flavor text at a popup shop exhibition in 2022 indicates Ryu is 173cm tall, hence his placement here.
Characters By Blood Type
Characters in Japanese media often have their blood type listed; the belief that blood type and personality are correlated is a popular superstition, not unlike star signs. This is generally hokum and doesn't really mean anything (and uh, is often touted by eugenicists, so that's not great), but for the sake of curiosity, I've grouped them up here!
Fun(?) fact: most Japanese people's blood (an estimated 99% of the population) is Rh+, meaning that there is generally no distinguishing between a positive and negative blood type, so all characters can be assumed to be (type)+.
