The absolute trophy raifu, because getting her is absolute ass, being more annoying than any other chapter exclusive. She is literally the only doll whose farm is so bad I will actually recommend autobattling rather than doing her map over and over. It's THAT bad for what you get and she isn't even worth it except for the 100% completionism.

Her tilebuffs are not great (6% Firepower, 10% RoF directly behind her), and her dodge buff is extremely blah for a 5/8. Her self-damage buff is not the worst while having surprisingly high Firepower for a 3 star SMG, but nowhere near as effective as SR3 or later, similar SMGs. Overall, a trophy raifu that you might be able to press into service if desperate enough, but I really wouldn't count on it.

AKA Shrimp

A strong direct damage SMG that badly needs an ACOG sight to boost her acc above the standard abysmal rating that SMGs normally get. She's basically an AR that can take the front row rather than an actual tank, since her idea of tanking is "If enemies are dead, I don't have to dodge right?" Very good for raw firepower type SMG/AR echelons, not so good if the fight(s) drag on and she takes damage.

If you have enough acc boost (which will need fairies, unless you're up against 0 evasion armoured enemies), you can use a critscope too, which makes her even dumber. Warning though that she relies VERY HEAVILY on gear, so be prepared to shell out for sweet sweet +10 Max Calib Bling Gear to truly make her shine. Also trips lolicon radars and may land you in jail.

I sincerely hope that everyone at this point has stopped trying to build echelons around her. Stop. It's ((current year)) just don't. Get help.
