Pretty Cure, Reach My Bright Past! is the super transformation phrase for Hikari and Akarui in Glistening Moon Pretty Cure! They must have the Shining Impact and already be in normal Cure form to activate.
The girls have one hand on the top of the Shining Impact when they shout out the phrase. The Impact then shines over the girls. Hikari is completely glowing green and Akarui is completely glowing purple. When the glow is gone, they are transformed into their past forms, and introduce themselves.
Both: Pretty Cure, Reach My Bright Past!
Hikari: It might have been a horrible past for us,
Akarui: but now it has become something new to begin.
Both: Our Bright Past! Glistening Moon Pretty Cure!
