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.

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.

Supernova is a shotgun pretending to be a handgun to go along with her shipmate GSh-18. She’s one of the most supportive shotguns available and she enables some real dumb stuff. You want to use MGs at night? Well, her skill allows for that. Do you need a little more defensive capability for your shotguns? She brings that too, all in a kancolle-flavoured package. Honestly, she’s not an automatic pick on every team. You’re likely going to have to drop a MG in your formation to make use of her fully, which can be an issue.

Her two main draws are her movement speed and her MG buffs. Her roller skates allow her to go almost as fast as a handgun, but not quite. Not much else to say about that, but main reason to take her is the MG buffs she provides.

While crit rate is nice, the accuracy buff she provides to MGs is fixed. This means that MGs are entirely usable at night. It bypasses the accuracy penalty that you would normally have with no PEQ. While not the most relevant thing currently, you definitely want to have Supernova in your back pocket for the future.

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.

Her skill is kinda neat, but ultimately, you're not going to get much mileage out of making 2~3* dolls better. Cool tiles though, I guess.

OK, your mileage may vary a lot for this one. Her Armor isn't great and she herself isn't exactly super tanky without her skill up. On the other hand, her skill might buff your other shotgun(s), so it may be useful for that.

Her Mod 3 unique equip is alright. It lets her punch through lighter armors, and otherwise is excellent at finishing off weakened enemies, rather than wasting full-power shots on them. This is usually a thing with rifles that don't quite instantly giblet their foes. Her tile buffs are pretty okay.

She's alright but not a priority.

She actually gets some fairly hefty stat increases in her mod, with Mod 2 hitting as much FP as M2HB. The issues that 2 stars normally face (low skill values compared to higher ones, etc.) are pretty solved thanks to being upgraded to a 4 star, and it also gives her extra base ammo which helps out a lot. Overall a cheap mod to get, and honestly you get a fair bit of value off even just Mod 1.

She's pretty much an all-rounder MG, and with the Mod 2 skill, technically you're not limited to just SGs, but uh... the shield values are so low otherwise that it only really helps armored things, though I guess some people might find a use for that anyway. MATH BIT: Her Special Equip actually isn't awful, but tbh you're better off with an EOTech in most cases.

Her original form can be found here.

Props for accuracy. She spends the animoo's story just living in the dorms and only coming out for tests or really weird situations where they cant spare bodies, and she's basically the same in the game - she'll be in your dorms a whole lot. She also has three unique items that affect her passive but otherwise all do the exact same thing. She isn't completely useless, but there's not much reason to pick her over other MGs that don't have finnicky mechanics, because you frankly will not need that many MGs anymore.

Suffers from "another doll does the same thing she does but better" syndrome hard, because that better doll is the 2-star Nagant revolver (which you have no excuse for not being able to get) who gets a mod to provide offense AND defense, while VP70's just defense with a +hit formation buff. Glock 17, MP443 and TEC-9 are also things. Basically, she's unremarkable and other things exist. Also IOP needs to stop experimenting with T-doll spines.

The weirdo, mildly creepy sweet potato. Honestly one of Waterkuma's better designs too. All sorts of adorable and frankly, the best shields you can get. Full party, 42-point shields, with stat buffs if the shield survives. The big thing is she can shield the whole echelon unconditionally, which helps massively for certain attacks like Doppel missile swarms, and can even negate them entirely with a bit of luck, or if you're using FP debuffers. As a result, she's a vital component of many weird teams purpose-built to kill some cheese enemies.

Farm your damned boxes and get her.

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.

Her pre mod form is here

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.
