She's basically a 5-star hybrid-type SMG, except she's not exceptional at either role she can do. She's meant to be a sub-tank, where she does not really excel. She's fine for generic use, but not great for high-end stuff.

The pinkhaired tryhard who is absolutely every bit as good as she says she is. 1 of the best sustained DPS ARs in the game, and can actually hit the RoF cap on her own. She can actually outDPS OTs-14 and 9A91 at night against up to moderately armoured opponents (moderate. Dont try to send her vs Hydras)

As a bonus, her mod skill ups her DPS some more by making her pull out ANOTHER gun and throwing extra attacks that do a % of her main damage, with more damage if paired with M4Mod.

Her mod skill however, does look absolutely retarded unless you're in her mod 3 form. Normally she's supposed to pull out another gun, but since her school skin and base sprite dont have that animation, she instead fires from her scope.

High end MG with good damage potential. Chance to fire an extra shot with every shot, and that has extra damage and can crit (it's not an autocrit, but can crit, see notes). At lvl10, it's actually very steady. With her unique gear, DPS is still extremely high vs single targets. However now we have bullshit MGs like Kord and the like, and being able to murder multiple enemies per shot is the current hotness for mobclear.
