Off-tank DPS that hates Elite units and provides various benefits. Her damage increase isn't stellar, but she has enough rider effects that you can probably find some use for her. Like C-MS, she can equip AP rounds. YMMV with regard to how useful that is.

Another one of those attack/defense mode sub-tanks. Weirdly cheerful unlike her somewhat gloomy sister, though she's probably even weirder in the head. The stat changes and adjustments are applied every 0.1 seconds, so it takes a few seconds for it to take full effect. The big quirk is she gains a flat amount of stats rather than a percentage which applies after all other buffs, but ALSO after the night time accuracy penalty, which means she's about as accurate as a PEQ-equipped AR at night while she's in attack mode. It also happens after Fairy debuffs are resolved, so you can also use her to dodge or attack even while under Parachute Fairy debuffs.

She's basically a 5-star hybrid-type SMG, except she's not exceptional at either role she can do. She's meant to be a sub-tank, where she does not really excel. She's fine for generic use, but not great for high-end stuff.
