Hinata and Kageyama are challenged to a match against fellow first-years, with the aid of second-year Tanaka.  While they practice for the match early one morning, Hinata demands Kageyama to give him a toss, to which Kageyama responds: "I don't think you're essential in winning," and refuses to toss him the ball.
