Casey Sagisu
Casey is kind of like the leader of the four guys. He goes to Tokyo college along with Kyosuke and Koji, but isn't part of the basketball team (considering his height). He's more into martial arts and weightlifting, but he still likes to go watch his friends play basketball. Even if it doesn't seem like it, Casey is very intelligent. He also lives at the school's residence since he moved from Osaka to Tokyo and his family still lives there. His parents want him to have a good education so they paid for his tuition and wanted him to stay at the school residence. Casey also likes to tease Kiyone, that second grader at TISS. When the four guys screw up on "missions", he is often to blame by Otomo since he is kind of the "boss" of the gang. He goes on a rampage when people ask him about his american name, since he really is japanese.
