These are both really good. I haven’t watched the anime for either of these (in fact, I just learned from this comment that there was an anime adaptation of Nozoki Ana), but have read the manga for both. Both of these characters are just really difficult to understand, but that is because they don’t behave in any way that is consistent. I get that people in real life can be inconsistent like this, but when you introduce randomness like that into fiction, it just makes it a bad story and the reader/viewer is left confused.
