She looks like a discount STAR-chan, although it's hard to describe anything that uses a stupidly expensive round like the 5.7 as a discount anything. She has a three second long cooldown and the skill lasts for two seconds. Her big thing is that she can also buff SMGs. She can be used either a mild firepower buff or an actually not awful evasion buff, the downside of which being that getting her evasion buff to work requires moving your dolls around.

Basically Glock 17 but with different tile buffs (and personally less goofy). Often compared to Nz75, but reduces damage outright instead of RoF so I personally find it better. Tiles are ok, and more importantly, unlike Nagant, she works the same day or night

She's not actually bad, but you won't usually need the exact combination of what she offers. She's there if you need her though.

Also she appears to have gacha currency on hand.
