This one is definitely kind of interesting.

Spoiler for harem?:

Granted it's looking like the redhead is the main girl(which btw, I hope she dumps the loli form soon), but Ferumina and Lilliana could be future heroines. Hard to say, but I wouldn't count them out. Especially since Ferumina is set up to travel with the MC from now on and learn magic from him.
