As the graviton bombings continue to become bigger and keep injuring people, Judgment decides to join forces with AntiSkill to find the culprit. Ruiko mentions to Mikoto about the Level Upper urban legend they talked about before, although she doesn't believe such a thing could exist. Mikoto accompanies Ruiko and Kazari to the mall, where she runs into Toma accompanying the little girl whose bag she recovered the other day. After noticing a connection tying the graviton incidents, Kuroko and Mii realize that the culprit is targeting Judgment members, with Kazari set to be the next target. After evacuating the mall, with only Kazari, Mikoto, Toma and the young girl left in the store, a graviton bomb hidden inside a plush toy goes off. Mikoto fumbles her railgun trying to stop it, but everyone is saved by Toma's powers. Mikoto manages to find and beat the culprit, Hatsuya Kaitabi, who wanted to punish Judgment for not protecting him from bullies, believing people with power like her and Judgment are corrupt. Mikoto punches him for using that as an excuse to hurt others, with Kuroko later telling him Mikoto would've still stood up to him even if she remained a Level 1. Mikoto meets Toma the next day who explains why he didn't seek recognition for rescuing everyone, which just serves to aggravate Mikoto further.
