He was previously a coliseum warrior and one of the Shield Hero's slaves. He is currently a resident of Lurolona Village and helps the Legendary Heroes with their duties.
Fohl seems to be around 12 years old and appears to be healthy. His hair is black and white and with just a glance, Naofumi could grasp that he was of a higher quality than the other slaves. His ears are thick and roundish for a cat, and his tail has impressive black and white stripes. While his pupils are blue, a portion of his iris has vertical stripes. The whites of his eyes give off an intimidating look and his savage facial expression spoke of his wild nature.
His level was 32, despite his appearance is fairly young for a level 32.
Fohl is very protective of his younger sister Atla, he feels that he is the only one that is able to protect her from danger, and he refuses to trust anyone else in that respect. Though when he knows that it's for the good of his sister he will swallow his pride for Atla's sake.
Fohl is half human and half Hakuko. He is the nephew of Aultcray.
Despite being a half demi-humans, both his sister and himself were treated as the lord of their house. They lived in the country which is at the outskirt of the country after the exhaustion of the wealth, they gave the remaining valuables to the servants and said their goodbye. It was mentioned that the servant moved to Siltvelt. As time went by, they become slaves due to the burden of the debt for Atlas' medicine.
He fought at the Colosseum to earn money for his sister's medicine. Many had eye for his talent and was planing to purchase him. It can be inferred that Malty too had laid her eyes on him for money won by Colosseum. Later they were both sold into slavery where they were both purchased by Naofumi.
