He was Angelique's father. He was a doctor.

When their village was attacked by Thanatos, he and his wife were trying to save the lives of the villagers until the end.

When he saw Thanatos preparing to attack his little daughter, he shielded her, receiving the strike instead of her. It is implied that he died because of that strike.

Angelique wants to follow in his footsteps and become a doctor just like him, so she can save people's lives, just like he saved hers.
