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.

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.

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
