Called it.... I thought maybe she just replaced her brain because it was too damaged, but it's a totally new person. Well, effectively same thing.
This new person might be "artificial" but there's no reason to think that she would be functionally any different from a regular human depending on that aliens technology. The way she even describes the AI makes me think it's not a "digital" brain, but a real one with an imprint using an AI. Sort of like digitizing your consciousness, then printing it onto a real biological brain.
So even though her "initial settings" are to be meek and docile....let's see how far that goes before she changes after being bullied.
OR....people think Haru is learning about how cruel humans can be but I don't think she thinks much beyond making the environment better for herself and the MC. She could....replace ALL the bullies. With more manageable clones. I'd bet on that outcome, except the author didn't show any of the bullies faces.
