The Children finally get to attend their first day of school, and during this time B.A.B.E.L. is keeping a close watch on their actions. Minamoto even infiltrates the school wearing a suit which renders him invisible so as to stop Kaoru if she goes too far and uses her powers against someone. One of their classmates notices the limiters on Kaoru, Aoi, and Shiho, and shows them that she too is an esper and wears a limiter. A boy named Tōno in their class dislikes espers and picks a fight with Kaoru, and an eraser flies and hits him in the head at this time, which makes him think it was Kaoru using her powers even though she did no such thing. Later, during physical education class, Tōno challenges Kaoru to a game of dodge ball, but if she uses her powers, he will never acknowledge espers. During the match, Tōno realizes that it was not Kaoru who threw the eraser before, and suspects that there are some invisible people around, which are in fact Minamoto and the other is later found out to be the chief.
