Konishi

Ayumi's classmate.

During episode 6, Konishi attempts to hurt Ayumi using a box cutter due to her enviousness. She is soon cornered until Ayumi uses her ability ''collapse'' which collapses both the roof above her and the floor below, killing her. Konishi, on the other hand, runs as the collapse started so that she would be able to escape the building in time.

In episode 10, Konishi attempts to hurt Ayumi, though fails due to Yuu saving Ayumi.
