Fillia is a homunculus created by the Einzberns who was sent to Snowfield.
Day 0 Edit
During the summoning of True Berserker, her body is taken over by a higher existence, claiming to be a goddess. Fillia manages to calm Berserker and heals its Master, Haruri Borzak, who had almost been killed by her own Servant. Ishtar forms a sort of alliance with Haruri.
