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.

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.

She has some of the highest damage and crit buffs in the game, with the best possible tiles ("All around her"), and her skill allows her to override the targeting logic of most other dolls¹, making them focus their fire some, very unlucky fucker (boss if present, otherwise furthest/highest HP/nearest enemy, depending on whether Contender is back/middle/front row). Oh and the skill doesn't wait until impact - the bonuses kicks in as soon as the shot leaves the muzzle. She also can equip AP ammo, which doesn't come up much, but there's a few fights later where this is immensely valuable and if you're using a HG vs armour at night, well... you know. Did I mention she has 40% base crit? She does.

The original Wonder Nine, she has... absolutely nothing in common with any of the other wonder nines in the game, instead opting to have a Tactical Throwing Ax which is more useful than her other gun. Basically, she's a bamboo spear unit in handgun form. Surprisingly good damage for such low base ATK if teamed with the right support squad. Seems niche, but she can actually 1-shot some bosses if setup properly.

+90% Acc Buff aura at 5-links. Also has a +damage up but that's just icing on the weird, underwater-themed cake. With NV equipment, allows you to completely destroy scouts in night battles if you're actually desperate for that. Normally not a buff I recommend, but she actually gives a lot of it so if you're wanting an actual acc buffer, she'll be 1 of the ones you want. Not as important anymore since there will be other sources of acc boost, but... sometimes you might want something?
