Personality and other traits: Lacks delicacy (he won't ask things like "Have you gained weight?" but he often asks about underwear color), honest, perverted, seems to like 2D girls (especially tsundere girls), machine-gun talker, dog-like guy, if you date him he's lovey-dovey and extremely devoted (absolutely won't cheat), barely fazed by anything said to him (even if hit, he just reacts with something like "Ow"), basically polite to everyone.
