Huo Yan Li

is one of the three Company Commanders of the 1st Special Fire Brigade.

Appearance
Foien is a young man with short, light-coloured hair that falls just over the top half of his face and eyes that naturally appear closed. He also has a chin strip and wears a dark-coloured hat. Foien's outfit consists of a dark-coloured cassock, topped by a light overcoat-like garment with a high collar and a skirt-like garment, dark shoes and a pendant with a cross-like symbol as a charm — an outfit, which is shared amongst the Company Commanders of his brigade. After his encounter with Rekka's superiors, Foien had one of his arms cut-off by a fire arrow.

Personality
In contrast to his long-time friends and team-mates Karim Fulham and Rekka Hoshimiya, Foien is a rather laid-back and responsible individual, who doesn't like to get worked-up and waste time with meaningless fighting. He abides to the etiquette of the 1st Special Fire Brigade strongly, going as far as to point out formalities, such as a dress code.

VS. 1st Special Fire Brigade arc
After the scuffle between Special Fire Force Company 5 and Special Fire Force Company 8, Foien and his fellow team-mates, Karim and Rekka, are approached by Leonard Burns and together they discuss the event. Later, when trainees from the 2nd, 5th and 8th Brigades arrive at the 1st Special Fire Fighting Cathedral and their training regiment begins, Foien is pitted against Tōru Kishiri, both of which refuse to fight. After training, when a Infernal was spotted in the area under the jurisdiction of the 1st Special Fire Brigade, Foien takes lead of one the squads. Later, Foien and Karim begin searching for Rekka, after it becomes clear that he is responsible for creating artificial Infernals. After the two find and restrain him, they look on as Rekka is killed by an arrow. When Karim becomes the following target, Foien pushes him out of the line of fire, but has his arm severed by the arrow in the process.

Fifth Pillar arc
After the great fire in Tokyo, Foien asks Karim if it was artificially created, and is informed that it was and by the White-Clad. As his missing arm is brought up, Foien says that losing it was God testing him, and guilt trips Karim into making the Ratomu hand-sign with him.
