Not even a solution in search of a problem, she's a bunch of solutions to a bunch of problems implemented extremely badly. A victim of Mica's experimental phase, as one of those dolls that don't fucking work. Instead of an infinite duration toggle, she has actual skill durations and alternating effects, making it increasingly unlikely you'll get the effect you want in the time you want, since you need to wait for cool downs to use them.

To top it off, her %s aren't even very good and are even more garbo during the day. There are better options if you need 1 or the other, like Mk23 or TEC9.

Another of those HGs that buff based on leadership position, with the Squad Lead getting an alright shield and everyone else getting an FP boost (as opposed to P22 which is positional based). Sometimes you might need that mix. If you do, there you go. Else, she's basically a slightly off-brand P22.

One of the more maligned, design-wise, of the Infukun rangers. As a character, she's OK I guess. As a design, she's not as good as the rest of the stuff Infukun made before he left Mica (G11 is peak Infukun). As a unit... she's actually kinda crazy, with a buff for every occasion that makes her one of the best and most flexible T-dolls in the game. Shields for the front, Damage for the back, Acc and Eva for the middle row in case you need that. If you could only get one doll from Isomer from farming, farm this one. Seriously.

If she offends your senses that much, stick a paper bag on her head.

Passively, she's Mk23 with better tiles. Regarding her active abilities, she isn't as nice as Mk23's straight damage upgrade for some, but better for others (such as fights with Grape that require her to shoot faster). They're similar but not interchangeable so you'll need to use the space between your ears.

Also she's kind of boring and has no easy jokes besides the Viking name, which doesn't suit her at all, so blah.

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.

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.

Honestly would be fodder but she has a decent enough tileset if you're lacking in HGs with FP boost. Gets considerably better in her mod form, which improves her tiles immensely.

+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?

Welrodski! ...By which I mean she's basically Welrod but 3 star, with lower numbers and an aura that wants her in the middle (or front works too). Usable if you lack Welrod and honestly not actually bad, but HG builds are cheap and she's pretty common so she might get annoying to get eventually. Also her -acc skill stacks with Welrod, and can be combined with a +evade skill for silliness.

Her mod has other uses and is quite interesting, see her mod entry here

MANNERS MAKETH MAN. Very good aura for DPS, and very widely used. As a bonus, she has a very good skill for tanking, and can actually be used as a tank for bamboo spear formations or helping other tanks. She has 40% base crit unlike other handguns (a trait shared with other single-shot pistols like Contender and Thunder .50.) so a suppressor is actually pretty beneficial on her, not that you have other much choice in the matter. But yes, you will be finding use for her. Note that her -acc skill does stack MULTIPLICATIVELY with other acc debuffers.

Her mod keeps her relevant well into higher difficulty content. See info on that here

Very good buffs, not good in her own stats though. Skill is blah-ish but serviceable at night. When she gets to MOD3, however. Becomes COMMISSAR NAGANT. May or may not land you in jail (or gulag as the case may be). She does say it herself afterall, about your odd taste...
