Filo

Filo is a "Filolial", which is a bird-like monster that hatched from the egg Naofumi Iwatani purchased from the slave master. She was born in bird form, but since her caretaker was Naofumi, one of the legendary heroes, she was able to change form into a small girl with wings like an angel. Although her personality is quite childish and often can't quite follow difficult conversations, Filo admires Naofumi as her master and Raphtalia as her sister. As soon as she met Melty, Filo instantly became friends with her, and have been besties since.
