Ryouhei Yamanouchi is the kind of guy who's immediately likable—genuinely friendly and straightforward, without any pretense. He was tight with Minato and Seiya back in elementary school, though they ended up at different middle schools. Once he got to his new school, he and Nanao hit it off right away and became close friends. He's a bit intimidated by Kaito's intimidating expression, though when they're alone he's comfortable enough to call him "Kaito-kun." What people tend to note about him is his emotional awareness—he's good at picking up on what others are feeling and looks after them with genuine care rather than obligation.
