How did you AI her voice (or the voice of any particular person)? And do you know WHY she hates Ekko so much? As soon as she sees him she always tries to kill him. I mean, that's some bad blood there... What could he have done that was sooooo bad?
I used elevenlabs. You can find loads of tutorials for it on RU-vid. Also I don’t think she hates ekko tbh, I think she just used that grenade when they fought because she had no other way out
