Marija, Buro, and Rin are skating at the Roller Disco, as Buro nervously attempts to practice skating, serving as a tutorial for her new swung heartbeat. Rin asks if they can stop to get some food, before Marija answers that the snack bar is closed. Buro then reveals that she stole the donut that Richard Hugh was carrying, to Marija's surprise. The two of them ask Buro if she can share the donut, to which Buro obliges, before abruptly skating away and telling them to chase her if they want to have a piece of the donut to eat. The two then chase after Buro, with the Cockatiel, Owl, and Samurai appearing, also participating in the chase for the donut. The player treats all six of them as they skate through the Roller Disco, with Buro teasing her two friends in the middle of the level, before being surprised by the Samurai's appearance, being carried by a bird above her. The level continues on, with a brief cutaway to Edega watching the six of them from a monitor. As the level ends, the outcome of the chase is dependent on the player's letter rank. Given that the player cannot progress the story without achieving a B-rank or higher, it can be assumed that only the B-rank, A-rank, and S-rank outcomes actually take place.
The B-rank outcome involves Buro refusing to share the donut between her two friends, before promptly letting the Samurai eat the rest of it.
The A-rank outcome involves Buro stating that the donut is "great" and hesitating before finally sharing the donut with Marija and Rin.
Finally, the S-rank outcome involves Buro stating the donut is delicious, once again hesitating before finally deciding to share the donut between her two friends; however, a bird swoops in and steals the donut at the last minute, leaving Buro as the only person who got to taste it.
After the level, the three girls speak to Ian and Paige for the final time, as he urges them to take better care of their health and getting sleep. Rin initially refuses, before Marija insists on listening to Ian, causing Rin to reconsider. Marija then compliments Ian and Paige, stating that they are "Middlesea's greatest attraction," before Buro and Rin interrupt to state that they think otherwise. Rin then declares that the three of them will "stay up all night" at the hospital. Ian tries to insist that they get some sleep, to no avail, as the collab story ends.
