Mikoto and Kuroko talk with Harumi Kiyama, the AIM specialist Mikoto had previously met, about the Level Upper. They are later joined by Kazari and Ruiko, the latter of which has the Level Upper, but decides to keep it to herself when Kuroko mentions its relation to criminal activities. Mikoto later catches up with Ruiko, noticing she's a bit down, and gives her some advice that levels aren't that important, though this secretly irritates her. The next day, Ruiko stumbles upon someone being conned by three thugs over Level Upper and can't bring herself to just run away, so she confronts them. Kuruko coincidentally arrives before Ruiko gets hurt and subdues two of the thugs, but has trouble using her teleportation powers against their boss, Trick, due to his ability to distort light affecting her calculations. He chases Kuroko throughout an abandoned building, but is defeated when Kuroko teleports the windows to cut through the building's supports, bringing the place down. Having barely just survived, Trick surrenders his Level Upper, which is revealed to be a music file. As Ruiko feels even more conflicted about what to do with the Level Upper, she encounters some of her friends, who were also interested in the Level Upper, and tells them that she has it.
