I don't really understand her. She's human, but she can fly (I guess Akadama-sensei taught her how to fly when he kidnapped her and raised her as a Tengu) but then, she's kinda left him alone.
And then she joins Friday Fellows, and eats tank hot pot. But she knows who and what this tanuki is. And later, she goes back to Akadama-sensei.
So,
- What exactly is her purpose?
- What's the reason behind this behavior of hers?
- Is she the antagonist or the protagonist in the series?
