Anime: Another
With Izumi you love her or hate her, I think it’s obvious which camp I fall under.
Okay she might not be the nicest. But she gets stuff done her way!
She takes initiative in finding the extra and ending the calamity.
Also she’s a slight tsundere, which you’ll find is a major plus on this list.
The fact that she’s also fairy humble and accepts her faults is like the icing on the cake.
