Natsuo is very sweet in my opinion, I just think she has trouble communicating/expressing her intentions. Maybe she's been misunderstood a lot, I'm not sure there's just something very good about her.

She's kind of masochistic in a way, right? Like, Natsuo wants to have opponents that are stronger than her because she loves the thrill of the fight. She's bloodthirsty. This is a really good manga.

Edit: Well, clearly I didn't read ahead, 'cause the manga outright said it haha

She probably said inferiority complex because of her brother. That's probably also a reason why she prefers fighting against people stronger than herself.
