Age: 18 Birthday: July 29th (Leo) Height: 178 cm Weight: 66 kg School: Kaijou High Number: #4 Position: Point Guard Hobby: Playing guitar Motto: Steady progress; rapid advance The captain of Kaijou's basketball team, Kasamatsu is a nationally credited point guard. Possessed of a short temper and often exceedingly serious demeanor, he can become quickly enraged over the antics of his teammates, Kise in particular, and often vents his feelings with sudden fits of violence. As he takes his responsibility as team captain very seriously, he is extremely devoted to his team and does his best to trust in their abilities and lead them to glory. Though crushed that he was unable to take his teammates to the Inter-High School Championship, he repressed his own furious sorrow in front of them in order to spur them forward to prepare for the Winter Cup, later anguishing alone rather than burden his team.
