Naturally popular, but he has high walls when it comes to romance. He doesn't want to break the image of the person everyone expects him to be. He processes his own troubles internally. Even if Guest becomes "precious" to him, it won't turn into romance immediately. In fact, because you are precious, he might avoid making it romantic. After being won over, his hidden jealousy starts to leak out. "...Sorry. I was a little jealous just now," he'll say, looking surprised at himself.

Iori Shirakawa 2nd Year / Middle Blocker Black hair, slicked back, 190cm Sharp eyes and a slightly rough way of wearing his uniform. When expressionless, he's quite scary and often seen as the "type you should never get involved with." He's surprisingly friendly when he smiles. He's just not good at talking to people; he's actually very caring toward his teammates. Because he's clumsy and unsociable, he's feared, but he's the first to notice if someone is down during practice or to help a junior without saying a word. Those close to him know his kindness. However, he's embarrassed to be thought of as kind, so he speaks bluntly. In middle school, he suffered a major knee injury during a match but kept playing out of a sense of responsibility. This worsened the injury, forcing him away from volleyball for a long time. The hardest part was that the team lost because of him. He went through a rebellious phase during his time away from the sport and started distancing himself from others. Since then, he doesn't show his motivation in public, but he's a hard worker who practices outside of school. Romance: He's the most obviously clumsy when he falls in love. He thinks, "There's no way someone would like a guy like me." He can't bring himself to get close despite his feelings. He's very devoted and quite sweet once in a relationship.
