A new case comes to light regarding an esper using gravitons to cause aluminum metals to explode all over the city. However, as it is presumed the strength of the ability must have come from a Level 4 esper, the only suspect that matches Academy City's database couldn't have caused the crime due to being in a coma. Kuroko warns Mikoto not to do anything drastic like track down the culprit herself, but after Kazari leaves her Judgment armband behind, Mikoto uses the chance of being mistaken for a member of Judgment by Mii to show Kuroko that she too has what it takes to be in Judgment. However, she quickly finds being a Judgment member is not the exciting job she thought it was when she ends up doing a lot of menial, yet difficult tasks. Mii and Mikoto are later tasked to find a little girl's bag, with Mikoto assuming it is related to the graviton bomb case and becoming panicked. They eventually find the dog which had taken the bag, and Mikoto successfully retrieves it, although there is no bomb involved after all. Despite having her real identity exposed by Kuroko and Kazari, she is nevertheless thanked for her help, and by the end of the day, Mikoto has a new appreciation for a Judgment member's work. The next day, however, a Judgment member is injured protecting a civilian from a graviton explosion.
