A new case comes to light regarding a user using gravitons to cause aluminum metals to explode all over the city, but the only suspect capable of doing this is 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, it 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 next tasked to find a little girl's bag, which Mikoto assumes is related to the graviton bomb case. 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. But the next day, a Judgment member is injured protecting a civilian from a graviton explosion.
