That caught her attention because fae eat what.

She knew of the other dangers having experienced that herself. From witches trying to use her in rituals to people trying to trap her in circles or trick her into giving them power. The knowledge of someone trying to eat her for their own gain is something new and something she rather not want to know but now does. "E-Eat me? Why would anyone want to eat a ghost? How do you even eat a ghost?"

Heiji, trust her, she would hate for something like that to happen for her too.
