I can’t tell if she’s a romantic or a realist either.

I’m thinking there’s a key to Chokki-chan’s appeal there. Somehow her world is both fantastical and mundane.

She’s not a chuunibyou - it’s not that she fantasizes about a fantastical life. It’s more that she recognizes her very mundane life for what it is, but sees wonder in it anyway.

There might be an existentialist lesson to be drawn there…
