is one of Junpei's old friends from middle school who is the star player of the soccer team. His athletic abilities and looks cause him to attract girls almost like a magnet. Because of his "perceived" experience with girls, Junpei went to him for advice on his girl problems early in the manga. Okusa's latent infatuation for Tsukasa, however, sometimes puts him—and his offered advice—at odds with Junpei. Yui greatly admires Okusa, and has a rather large infatuation with him.
