Not even a solution in search of a problem, she's a bunch of solutions to a bunch of problems implemented extremely badly. A victim of Mica's experimental phase, as one of those dolls that don't fucking work. Instead of an infinite duration toggle, she has actual skill durations and alternating effects, making it increasingly unlikely you'll get the effect you want in the time you want, since you need to wait for cool downs to use them.

To top it off, her %s aren't even very good and are even more garbo during the day. There are better options if you need 1 or the other, like Mk23 or TEC9.

Props for accuracy. She spends the animoo's story just living in the dorms and only coming out for tests or really weird situations where they cant spare bodies, and she's basically the same in the game - she'll be in your dorms a whole lot. She also has three unique items that affect her passive but otherwise all do the exact same thing. She isn't completely useless, but there's not much reason to pick her over other MGs that don't have finnicky mechanics, because you frankly will not need that many MGs anymore.
