Unfortunately, an incident occurred that caused Nina to be teleported to a strange world called Earth and she temporarily had no way to return to the Aionia world. Because she did not bring any valuables with her, Nina quickly became destitute on Earth. Nina decided to become a maid to find a kind-hearted person to rely on and get by while trying to find a way to return Aionia world.
