Babushka says not one step backward. Every seventh shot, she gives a damage bonus! Also, the thing starts active, making her one of very few buffers with a start-of-battle skill activation. Her first skill is still defensive in nature, and the percentages got bigger. She's actually useful in a number of situations, either for reducing enemy firepower in specific fights (usually Gundam or tank related) or just the straight DPS boost from the get-go. You only really need her up to Mod 2, but the Mod 3 art is cute.

Her pre mod form is here

One of the best login dolls, although not one you'll regularly use. Her skill gives a massive 40% FP debuff to enemies, making her a choice pick for doing things you're really not supposed to be doing. Combine with another FP debuff for better uptime to make it extra spicy.

Keep in mind that her skill works best at night.

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.

aka G17 ingame; Used to be decent when you actually needed evasion buffs, but who needs that in current year?
