Dream of the Sky is a series of sidequests from Gravity Rush 2.
A series of young boys challenge Kat to race against their pet seagulls. This manifests in an aerial race where Kat must go through floating rings that serve as checkpoints, similarly to the race challenges.
In the first race, the seagull is distracted by an old man throwing bird feed, slowing it down and allowing Kat to win. In the second race, a similar thing happens when the seagull is distracted by a flock of other seagulls. In the third race, nothing distracts the seagull, but Kat is still able to win through sheer speed.
