She's one of the dolls of all time. Yup.

Currently the Night Commoner, with her performance being the lowest among the three heavily used night battle ARs. However, through the mod system, becomes the Night Goddess/General Secretary. Yes, even better than Groza. Power to the people! Overthrow the monarchy! Or something.

Without it, she'll somewhat outperform daylight ARs at night, although not as well as the rest of the Night Royalty. Even then, the stronger ARs will still outdps her.

Her mod entry can be found here.

The cinnamon roll heroine. One of three ARs that buffs other ARs. A decent DPS who buffs other DPS. Later upgrades into a fucking metal gear. Which you should 150% get. So regardless of how good she is now, raise her anyways.

You can find her mod here

Very solid 3 star that is actually better than most of the 4 star RFs (SVD, G28 and occassionally T5000 can outperform her, but she'll handily trounce most of the rest.)

You get her for free and she's amazing, due to very fast base RoF for a rifle. Less good now as the better RFs come along, but will last into the higher chapters easily. Now has her mod available.

Choco tabemase? You get her for free and she performs OK. Has a long history of suffering in the game and may suffer from PTSD. Damage bonuses are nice, and she's just strong enough to take down a Jupiter cannon by herself, provided you have some cannon fodder between her and the Jupiter (which is mostly why she has PTSD).

She used to perform really well, and she does perform OK for cost to raise, but a 5-star and 3-star AR cost the same to actually use, and the newer ARs are much, much shinier. She's still OK but don't get too attached, you'll have better soon enough. Maybe she'll get a mod someday.
