Remembering that she knows the MC, and if I remember right even admired him in some way (even if not in love with him like some of the girls in his flashbacks), I wonder when she will meet him again. From remembering her thoughts when meeting the goddess, there is a chance she will join his group maybe?
Also, I'm still waiting for when she finds out Mio's past life.
She seems to take that as the strongest opponent she would ever face, but from how Mio reacted when she asked if those creatures some chapters ago were more dangerous than her Mio seems to not even be trying to hide it, it just never came up as far as she is concerned.
