Girl 1 (left and center) is Ilaria "Lilly" Brynn, commonly referred as Lilly, is one of ActuallyRea's Pokemon trainer OCs. Presumably Girl 2 (right) could be Lissy who is the main character from their Pokemon Nuzlocke comic LissyLocke given the similar hair design. Both were supposed to be in LissyLocke reboot set around during Pokemon Sword and Shield release.
