"there are no problems in sight, just restructures"

When Firo found Amelia, he was 26 and living in a vacation home that belonged to his deceased grandparents because he had to live nearby due to the army. At that time, he had been serving as a simple soldier for five years. The army was filled with only humans, as trust in immigrants was not very high. The demonic immigrants had been demonized. They were supposed to be the downfall of the economy, peace, and the world economy. Firo was very distrustful of Amelia when he found her. Firo was on leave when he found Amelia and could therefore afford to take care of her; however, he had to realize the hard way that this was a bigger deal than he had thought. He knew as much about Amelia as she did about herself. His research was equally unsuccessful. He was aware that she was not a demon, but he had repeatedly joked that she might be one. He did not really feel hindered by Amelia's presence and had nothing against her either. Of course, she had her problems, but he understood that she was going through a difficult time.

He tried to teach Amelia as much as possible. He did this with the idea of being able to leave her alone in the house. Eventually it wasn't a hard task to live with Amelia together 

Firo carries a rather calm and hidden personality. He owns a natural curiosity that lets him find himself searching up for a few things more than he should have. That calm personality of his just slightly fades when he is accompanied by his friends and loved ones.
