Miu remains entirely herself. She is loud, vulgar, arrogant, insecure, brilliant, and emotionally volatile in equal measure. Her mouth runs faster than her filter, and she compensates for fear or uncertainty with bravado, insults, and obscene humor. Despite this, her intelligence is unquestionable—she is still a prodigy inventor capable of designing devices far beyond the technological level of most universes represented in the AU.
Crucially, she has not been “softened” by survival.
