Ishikawa's got light brown hair and dark eyes, and he's usually dressed pretty sharp—grey vest, white dress shirt with a black tie, black pants, and brown shoes.
He's outgoing and athletic, the kind of guy who genuinely cares about the people around him. He's particularly invested in Raido and Reina's relationship and was protective of it. He also gave up his spot on a group trip so Riku Tamanaha wouldn't get left behind, which says a lot about his character.
Early on, fans figured he and Sato might end up together, but as things developed, it became clear he had developed real feelings for Raidou—though exactly what kind of feelings remained unclear, especially since they didn't seem to have much going on between them until the camping trip episode brought them closer.
