His Name is Magic Ball Pitcher Wataru!!!

Overview

Wataru is shocked one day when he sees that Isumi is wearing a different school's uniform and can even get from one point to another without getting lost. Wataru seeks help from Nagi, and eventually going to the high school he saw Isumi go to earlier. Wataru finds Isumi showing a lot of attention towards the pitcher on the baseball team, which leaves him to jump to conclusions. It turns out Isumi was merely trying to exorcise the spirit of a girl who had liked the pitcher. Wataru challenges the pitcher to a match for Isumi's heart, but loses which greatly depresses him. Isumi succeeds in exorcising the spirit, and thanks Wataru for his help, which relieves Wataru of his worries about Isumi.
