A ridiculously overpowered handgun in the right hands. If you know what you're doing, she is absolutely bonkers. Led to a meme on older servers where "the practical number of RF teams you could field was equal to your sets of Px4 and Five-seveN."

Strictly speaking it isn't true, but it gives you an idea of how valued she is. What she does with her active skill (at lvl10) is reduce crit rate by 20%, but increase your crit damage multiplier by 50% for all dolls in her tiles. Considering that crit damage STARTS at 150%, and that its tile based, which means you can engage in tile fuckery (which makes these effects stack MULTIPLICATIVELY), and there you go. For RFs, with a +10 Gold Scope and 5-7, they maintain 100% crit rate through all this. For ARs, you need to worry about the math a bit more, but it is generally an overall increase unless your critscopes suck.

Works with TAC-50, which is part of why she was so hideously overpowered.

Aka 64 Shiki if you're a weeb.

She's a bit of a complicated unit in that certain enemy thresholds alter what her skill does, thus making her work better vs bosses (with her colossal 90% FP boost for a few seconds) than for regular encounters. However, the timings are awkwardly short for the big boost, and the 2nd half reduces her firepower a bunch but also buffs the hell out of the stuff in front (which, if it's SR3, means more damage for her.) Note that the skill is less awkward than it seems, as it counts doll groups, rather than individuals, so 5x 5-linked enemies is totally fine, and so on.

Unfortunately, they removed cool tile buff tricks so her potential of giving insane buffs is a lot more limited than before

Her basic tile buff is excellent, which instantly makes her the best handgun to use with MG echelons at day. It's also good for AR echelons at night, if you don't have 5* PEQs on your ARs, similar to SAA. The combination of a significant HG evasive buff plus very decent rifle damage buff also makes her a solid alternative to Grizzly for RFHG echelons. So far, so good.

She used to have some tile fuckery, but they have since fixed having fun. At least she has a mod now.

When her artist read up on her, she was kind of horrified and drew a weak-bodied hospital patient who hates her defective form. In the actual game, she is a good performance AR-buffer. Her skill is somewhat peculiar, because she does not buff herself, but she more than makes up for it by turning the other two ARs into veritable murder machines. Presumably because the other ARs are horrified at the thought of her dying out with them and wanting to kill the enemy as soon as possible.
