She obviously has identity issues since she's a white rapper in Japan who LARPs as an anime girl and plays ttrpgs, so she'd probably have an ability that lets her steal Nen. Hard to say how she'd do it, but it would probably involve music. Maybe whenever someone is listening to a song she produced, she can see it on her phone and use their abilities as long as they continue. Something like that. This is a low requirement for stealing an ability, but disabling it is also 100% in the victim's control and she'll be just as surprised as her opponent in a fight, so it's pretty dangerous.
As a vtuber, I think she has autism and this makes her cringey but also relatable.
