@KoL Righto, Miyu sabotaged her reactor to blow in a minute, then tried to sneak for an elevator in the smoke. She went for flight because she was worried about the swords all along all the surfaces in the room. If you're gonna kill/capture her, go ahead, she's got no defensive or offensive options left. Her remaining tools are a medkit and a human-tier body capable of flight.
Also, the missiles aimed at Ni-Mu were supposed to do a whole Itano circus spiel and hit a circle around her, because they expect Ni-Mu to easily dodge or defend herself, and Miyu didn't know whether the swords around Ni-Mu would also have the whole explode on contact thing, and figured hitting Ni-Mu with one of her own attacks is Miyu's only vague chance of inflicting damage.
In retrospect, a ring of explosions around you might interfere with your ability to sense sound and vibration, but, eh, probably not.
