Oh, I know. I was actually suggesting it is a real Mystic Eye, but she doesn't actually have control of its activation nor memories of it being active. Her chuuni mindset is legitimately her mind protecting itself from a magic she cannot control.

EDIT:

Entirely up to you, though. Just something I thought about.
