Karim Flam

is a Second Generation Company Commander of the 1st Special Fire Brigade.

Appearance
Karim is a young man with short, straight light-coloured hair brushed to the front, with the sides of it being shaven dark-coloured hair. He has small and lazy dark eyes and is generally seen with an angry facial expression. His 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 the 1st Special Fire Brigade. Karim wears headphones when on the battlefield, instead of the usual helmet, and is seen wielding musical instruments, which he uses as weapons.

Personality
Karim is a rather serious and cautious individual, showing a high disrespect towards strangers, which can result in him insulting people. He gets annoyed rather quickly, even with him comrades, and shows a dislike in playfulness when it comes to a fight. Though somewhat brash and bad-tempered, Karim has portrayed respect towards his colleagues and abides to the etiquette of the 1st Special Fire Brigade. He had great leadership skills and a sense of justice, showing willingness to reveal highly sensitive information about his team-mate and his schemes to outsiders, even after catching them snooping around his belongings. Karim greatly values his friendship with Rekka and Foien.

Abilities
Karim is a Second Generation, who has awakened the ability to generate ice through his musical instrument using Thermoacoustic Refrigeration — an ability that allows him to collect heat energy inside the instrument, transform the heat into sound, thus decreasing its temperature, and, by repeating the loop several times, create pillars of ice, which can be launched at opponents or be used to incapacitate Flame Humans. In simplistic terms, Karim has compared his ability to how air conditioning functions. He noted that he can take heat energy, turn it into sound and then into frost. Karim also carries a bell with him, which he can use to create an alarming noise that can, with the help of his ability as a Second Generation, reduce the amount of heat and collect it for his instrument.

VS. 1st Special Fire Brigade arc
After the scuffle between the 5th and 8th Special Fire Brigades, Karim and his fellow team-mates, Rekka and Foien, are approached by Leonardo 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, Karim suspiciously observes all of them and later leads them to Leonardo. In the training grounds, Takeru's attack, which was directed towards Rekka, starts heading straight towards Karim, which forces him to unveil his ability and freeze the attack, informing the outsiders of him being a Second Generation. After training, when a Flame Human was spotted in the area under the jurisdiction of the 1st Special Fire Brigade, Karim takes lead of a squad and incapacitates the threat. Afterwards, Shinra spots an artificial creation of a Flame Human and finds Karim and Rekka at the scene of the crime, but does not approach them about the incident. Some time later, Karim catches Shinra and Arthur snooping around his room, where they find the key to the artificial creation of Flame Humans, but Karim informs them that the real culprit behind the incidents is Rekka.
