Heckler & Koch P7 – ★★★★ Handgun
Catgirl nuns should be met with fire. Honestly has some use but.. you are likely better off with someone else, due to her aura shape forcing you to push her to the side to give your tanks evade and kind of unflattering aura in general compared to other 4*s. Probably better as cores but she does have her uses. For example, combined with Welrod and Makarov, the +evade/-acc combo does funny things to enemy hitrates (though its impossible to reduce hitchance to zero). Niche, but you may find some use for such things.

Dusk's Note#
Interesting image aside, the actual impact of EVA buffs is hard to quantify, and varies between fights, enemies and maps. In many cases, she doesn't provide that much, and her tiles are hard to use. Often, running PSM gives you better mileage if you don't need that 20% ROF, and if you need that 20% ROF, just run something better that gives more ROF.
Significantly worse than Welrod at her only theoretical use, and not significantly better than Makarov. Use Welrod or Makarov if you don't have her. If you have neither, you probably aren't at a position which P7 is useful anyways.
If anyone is wondering, I like Vestal more.
