After receiving word from Dr. Oid, Pluto returns to Earth to see his planet status reinstated. However, his journey is interrupted by the planets' moons, who seek to avenge their parent planets and defeat Pluto. Once Pluto arrives at Earth he encounters a determined Moon (Luna), who ultimately loses to Pluto. After this loss, the moon is subsequently hacked by Dr. Oid's binaural beat hack through a replacing of Luna's headphones with exploited UAI headphones. However, Pluto is not alone in the song, Nexus, as he is joined by Eris and their own moons.
