Whilst out on patrol, Kuroko and Kazari come across a couple of petty thieves stealing from a car in broad daylight. Kuroko charges in despite Kazari's warning and ends up getting ambushed, allowing the thieves to escape, injuring Kazari along the way. Afterwards, Kazari scolds Kuroko for not listening to her and becomes angry at her when she forgets a promise they made. Later that day, Kuroko tells Mikoto about how she and Kazari first met when they were younger in Judgment. When Kuroko and her senior, Mii Konori, got involved in a bank robbery, Kuroko's rash actions led to Kazari being taken hostage by the bank robber, whose esper ability to throw steel balls at a consistent speed without stopping injured Mii when she protected Kuroko during another rash attack. Having realized her mistakes, Kuroko managed to teleport Kazari outside to safety while she faced the last bank robber alone. In the end, she was saved thanks to Mikoto, who anonymously answered Kazari's pleas for help, and managed to apprehend the robber. In the process of telling the story, Kuroko remembers and realizes the promise she made with Kazari; to be true to themselves and become full-fledged members of Judgment together, and goes to apologize to Kazari, joining her in pursuing the car thieves.
