Sailor Moon: Into the Sailor-Verse created by Illumination and Toei Animation, and they'll be Sing Girls getting along with human girls grown up to adults after the events of Pretty Guardian Sailor Moon (2003 live-action series)
Porsha Crystal as Sailor Wolf the protege of Sailor Moon
Suki Lane as Sailor Saluki the protege of Sailor Mercury
Rosita as Sailor Pig the protege of Sailor Mars
Ash as Sailor Porcupine the protege of Sailor Jupiter
Meena as Sailor Elephant the protege of Sailor Venus
And
Nooshy as Sailor Lynx the protege of Sailor Luna
So those will be Sing Girls as Sailor Guardians in the right colors of their Sailor Guardian Suits based off their defaulted clothes from the previous films, and the Sailor Guardian Suits would be based on the 2003 live-action Sailor Guardians that are recolored versions of the live-action Sailor Guardian Suits from Pretty Guardian Sailor Moon, so the Sing Girls from Calatonia are going to help the human mentor gals from Juban City of Tokyo to stop the new villains from disaster, and they'll be in the 1st film before returning in the upcoming sequels of the franchise
