She doesn't get why people worship All Might like a god

Yuuto's aggression is not directed towards anyone specifically it's just a side effect of constantly being envious of other's quirks, overthinking things and ridiculing her every action

Yuuto's public aggression also fades always as she gets older. She's still the same angry person but bottles it up very well

She looks up more to pro enhancers greatly, not All Might

Her mom went missing after a fight with a villain but isn't dead, just got teleported across the world because the villain's quirk acted up on its own and sent her somewhere totally different

Her quirk activates (personal power up) when startled. Using 'Personal Power Up' on her own is much more difficult but can be trained to make it far more easier; like a sore and cramping muscle that hasn't been used in a long time

Before moving to UA, Yuuto would use her quirk to help her dad sleep easier since he could barely get any sleep because stress got to him
