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.

21 Armour and her HP isnt high enough to make up for it at a mere 231 per dummy link (compare 275 for SPAS-12!). Her skill doesn't help her tank, and while her skill kinda helps a little for mass knockback, her ammo count is awful, so you can't rely on it.

She's better than nothing, but you already get SPAS-12 for free.

The first DPS handgun that actually produces well.. actual dps. Also might have possibly gotten lost from Kancolle.

Her skill gives her doubleshot and 100% crit rate while active, which is surprisingly strong on a handgun. Dont knock it.

Great as the damage dealer for 5HG teams, or a variety of misc. uses since she actually has alright tiles too. While she's not super impressive during the day (especially compared to good ARs), she shines at night due to being able to pack 100% crit rate while equipped with a PEQ.

Her main disadvantage is what a pain in the ass she is to get, since you need the first 5 volumes of the Comic in the Cafe. Her special costume requires the other 5. This is a heap of batteries.

She's pretty decent though, so it's not exactly a waste to do it.

She also has a mod, and the review for that can be found here.
