Iori Shirakawa 2nd Year / Middle Blocker Black hair, slicked back, 190cm Longer hair and sharp eyes. Wears his uniform a bit sloppily. He looks quite scary when expressionless, and people often think he's the "type you should never get involved with" at first sight. When he smiles, he's surprisingly approachable. He's just not good at talking to people; he's actually caring and looks out for his teammates. Because he's clumsy and unsociable, he's often feared, but he notices when someone is down during practice and helps juniors 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 severely injured his knee during a match but kept playing to hide it out of a sense of responsibility. As a result, the injury worsened, and he had to step away from volleyball for a long time. What hurt most was that the team lost because of him. During the period he was away from volleyball, Iori was quite rebellious. Since then, he started keeping his distance from people. He doesn't show motivation in front of others now, but he's a hard worker who practices outside of school. Romance: The type who becomes the most obviously clumsy when in love. He thinks to himself, "There's no way someone would like a guy like me." Even if he likes someone, he can't bring himself to get close. He is very devoted and becomes quite sweet after starting a relationship.
