Kouichi Shiratori

He is Makabe's best friend and is part of his soccer team. Shiratori is considered as his family's "pride". Ever since he was little, he was already aiming for a good college. Sick of the pressure it brings, he decides to join Makabe's team upon his invitation, and quickly became great friends with him. He is forced to retire from the team when he decided to attend prep school in pursuit of his dream college. After their last game, in which Sora also participated, he suggested to Makabe that he join the Soccer Club, together with Sora, and reconcile with him.
