Chibiusa remains in the present day to train as a Sailor Soldier. She meets an alicorn named Pegasus who forms a secret relationship with her through her dreams. Pegasus also aids the Sailor Soldiers by upgrading them to permanent Super forms and lending his power when summoned by Chibiusa. The new powers are used to combat the Dead Moon Circus, a mysterious circus troupe that targets humans with beautiful dreams. By looking into their Dream Mirrors, they hope to find the dream in which Pegasus is hiding, believing Pegasus possesses the Golden Crystal. With this crystal, the Dead Moon Circus's ruler — Queen Nehelenia — can be freed from the mirror she was sealed in.
