A kid becoming wilder after being repressed. How strange. It's almost as if actions have consequences. Also, she's a kid. Treat her like one.
Nah, it's not the martial arts. It's how you treat her that makes her so high strung that she can't always control herself.
Yeah, there's no way she can do that. Just spout some science and suddenly she can hit several times stronger than him. I also kinda doubt her punch packs 2/3 of a metric ton.
Why would a girl be scary if she can punch? That's weak.
