The Firefly Sisters

The Firefly Sisters is the name of a group of three infamous ex-Twintail warriors known for implementing "scorched earth" tactics, through their excessive use of pyrokinetic abilities.

The Firefly Sisters made their debut shortly after Rika first transformed into Tailsilver, conspiring to hand her back over under Imperial custody after they found out through an interrogation of ARC captain Echo-12 "Dogma" that every Imperial operation thus far in their city was solely intended for Rika's recapture. So the sisters attempted to apprehend Rika by force, but all three were easily defeated by Tailsilver's overwhelming saber skills and electrokinetic abilities, forcing them to back down.

The sisters reappear later in the series, where they reluctantly aid Tailsilver in defeating the Phantom Guard, one of Tailred's most deadliest agents. Despite the sisters' advantage in numbers, the Shadow Guard had no trouble defeating Mika and Mii, leaving an exhausted Mikoto to fend for herself. Mikoto's pyrokinetic abilities were no match for the Phantom Guard, and the ensuing fight ended quickly with Mikoto getting disarmed and thrown effortlessly towards the wall, where the Phantom Guard proceeded to strangle her to death.
