Keiichirou Senda
A member of the Seishū baseball club, in the same year as Kō. He is the only first-year student to pass the baseball club placement test, and therefore on the first-string team. Because of this, he frequently brags about how good he must be. Coach Maeda comments that Senda is too much of a showoff to be a good pitcher, but that he would likely make a great shortstop. He constantly pursues Aoba, trying to get her to date him. After making too many errors as pitcher, he is demoted to the prefab team, where he plays shortstop. After the sacking of coach Daimon, he becomes the starting player in Seishū baseball team. His appearance and personality are similar to Ryūtaro Kine from H2.
