At some point, G&K started running out of real guns and broke out more of the early 20th century guns.

Surprisingly, the dolls with them are actually not godawful.

If she's the leader, she gives a general buff, but whatever, most HGs do that. What makes her interesting is that if she's NOT the squad lead, she buffs the hell out of them, thus making her useful in any formation where you want to pack as much as possible into one doll's ability. Lookin' at you, M4, IWS. (And a few others)

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.

Chinese Makarov clone. Similar job to SPP-1, but less boosting your side's acc and more on lowering the enemy's evade. With fairies now existing she's kinda useless.

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.

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.

The doll is basically Spitfire with slightly different buff tile layout/focus (less FP, more Acc). Frankly, she's really boring statwise and enemy RoF reduction is usually worse than FP reduction (which is good for armor/shield tanking) or acc reduction (Which is good for Eva tanking) and the Spitfire entry has the rest of my thoughts on that.

She thinks of herself as an elite doll, due to the P226's previous adoption by the US Navy SEALs (hence the Seal she has with her) and has a bit of a rivalry with M9, claiming she should absolutely be the more popular one. More info on the notes.

3* equivalent of Colt SAA. Useful if you're short on REAL AMERICAN GUNS, but given that SAA is easier to get, probably more a trophy raifu.

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.

+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?

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.

Another fucking CZ-75 clone, this time from China. Unfortunately for her, her buffs and skill are all over the place, and most of the time you're better off with a more focused HG – Type-92 gives you a lot more dodge and not significantly lower DPS, Grizzly gives you a whole fucking lot more DPS, Welrod is a better debuffer, etc.

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

Decent overall damage buffer with bonus evade for the tank. If you have her exclusive equipment, her buff is a bit more valuable. Nothing super standout though.

A Britbong copy of Cz-75! ...And kinda weird. She's sort of setup for the 2MG 2SG 1HG thing that doesn't come up much and is defensively oriented, but sometimes it comes up. Just... not on any content currently. Does occasionally see actual use as a result, but she's not going to be your first pick for most jobs.

The problem is that RoF reduction is kinda meh, as while it does reduce enemy DPS, it merely slows down the rate of being shot, as opposed to making shots worse (good for SGs as their armour can more readily absorb it) or less accurate (which helps Eva tanks just not be damaged entirely), making it the weakest of the enemy attack stat debuffs.
