Okay, I'm done. That was the most asinine chapter of anything I think I've ever read.
I don't need things to be realistic, but this is just insulting to the reader. 26 chapters in, and they reveal that people do in fact have magic powers, which harukana was just using to bother people.
They've hinted that she bothers people due to some part of her tragic backstory but they haven't devoted any panels to explaining it, they're all being used up to show her bothering people.
All right, I'm done lamenting this character. Just going to drop the manga and save myself some brain cells.
