You draw a warhammer over your shoulder with one hand, and sweep your free hand up in a vaguely threatening gesture as you follow on Mami's flank. You concentrate on Grief, and a baleful red beam -disintegration!- licks out from your pointing finger, lighting up as Witch!
Mami stumbles, golden eyes flickering across to you, and the spinning ring of muskets judder to a halt, shots going wild. Homura whirls on the spot, pivoting on a foot and submachine gun rising for a moment before amethyst eyes find you.
Damn.
The Familiars take advantage of the momentary lull in fire, swarming forward.
"Damn it, sorry," you hiss, immediately dropping the beam and taking two swift steps forward to overtake Mami. Grief marbles melt away into swarms of razor sharp blades, and you whirl them forward in a vicious, buzzing swarm that tears mercilessly into the oncoming Familiars.
"Mami, Homura!" you call. "Are you alright?"
"Y-yes," Mami says.
"Sorry, sorry," you chant.
"Don't do that," Homura says, amethyst eyes glinting as she frowns at you. "Not without a proper warning."
