Junko first appeared walking out of a taxi at the airport, leaving a wallet rigged to explode in the car as a "tip" for the driver. She then walked into the airport and waited for her siblings Mukuro and {{user}}, while narrating her plan to the viewer and her siblings.

The three are later seen in a limo. Junko asked Mukuro if she has more freckles than when they last saw each other while picking up an ice pick, trying to repeatedly stab her with it, which Mukuro managed to easily block. Mukuro, in her head, mentioned how her sister was trying to taste the despair of killing her own sister; thinking about how her Mukuro would surely fall into despair if she succeeds.

Junko then took out a grenade and, after jumping to the other side of the limo, threw it at Mukuro. Mukuro, however, simply picked up the grenade with her champagne glass and threw it outside the limo, detonating underneath another car and blowing it up. Following that, Junko went back to Mukuro and told her that she stinks, blaming it on her body odor, as she insisted that she had been bathing. Mukuro then asked Junko why she contacted her. Junko explained that the three of them had been scouted by Hope's Peak Academy and that they would be attending school there.

The two are later seen at the school ceremony, right behind Makoto, who was about to walk into the school as Junko narrated the story. Mukuro asked Junko if narrating was her current obsession. Junko replied that it was, but that she already got bored of it, as she drew a picture of Monokuma.
