The main Futari Wa reference is their transformation (futari wa maho/kiseki). From the other side, Mirai and Rico didn't say "Dual RaPaPa!" (but they spell it harmonizely - possible Suite reference). We should wait for their finisher.

Also, they can be magical girls, miracle girls, witches or even Legendary Mahotsukai, but they still fighting hand to hand.
