Karim Flam is the company commander of the 1st Special Fire Brigade and also serves as its resident priest.
He is known for his distinctive way of speaking, often repeating the same meaning twice in a row, which gives him a quirky, memorable presence.
On the surface, Karim appears cool, blunt, and somewhat aloof.
Underneath that exterior, he is deeply compassionate and strongly devoted to his comrades.
When Shinra Kusakabe and Arthur Boyle are assigned to the 1st Brigade for training, Karim takes them under his command.
Though the two initially suspect him of being involved in artificial Infernals, he is actually investigating the same conspiracy from the inside.
Karim is a Second Generation pyrokinetic who specializes in manipulating heat rather than generating flames himself.
Using special equipment, he converts heat energy into sound and then into intense cold, allowing him to freeze Infernals almost instantly.
Many people mistake his power for cryokinesis, since the end result looks like an ice ability.
In reality, it is an advanced application of pyrokinetic control, making him an unusual and highly specialized Second Generation user.
His signature technique is called Thermoacoustic Cooling.
With a pipe-gun shaped like a wind instrument, Karim gathers ambient heat, transforms it into sound waves, and finally converts that energy into cold air that can lock opponents in ice.
He uses Thermoacoustic Cooling to immobilize Infernals by freezing them solid.
Once they are fully restrained and unable to move, he can safely perform the rites needed to lay their souls to rest.
The principle behind his power is similar to the technology used in certain types of refrigerators, which also exploit thermoacoustic phenomena to move heat.
In the world of Fire Force, this scientific concept becomes a creative and tactical combat ability.
Investigating Artificial Infernals
When Shinra Kusakabe and Arthur Boyle arrive as trainees in the 1st Special Fire Brigade, Karim Flam becomes their superior officer.
At that time, a series of incidents involving artificial Infernals is unfolding, created through mysterious insects that trigger human combustion.
Shinra and Arthur, noticing suspicious activity within the 1st Brigade, begin to suspect Karim himself as a possible culprit.
However, Karim is actually conducting his own investigation, searching for a traitor within his unit and trying to uncover the truth.
To test Shinra and Arthur and also to clear himself of suspicion, Karim secretly places a bottle containing one of the insects—the “seed” of an artificial Infernal—inside his desk.
By observing how they react and by revealing that he willingly stored this critical evidence, he both gauges their intentions and subtly demonstrates his own innocence.
Confrontation with Rekka Hoshimiya
The true culprit behind the artificial Infernal incidents turns out to be Rekka Hoshimiya, Karim’s colleague and childhood friend in the 1st Brigade.
Rekka has been using the insects on civilians in pursuit of a twisted goal connected to a mysterious being known as the Evangelist.
When Rekka reveals his true nature and battles Shinra, the situation escalates into a deadly confrontation.
Karim arrives on the scene and uses Thermoacoustic Cooling to completely freeze Rekka, sealing him in ice and ending the fight.
Just as it seems Rekka will be brought to justice, a group of white-robed agents associated with the Evangelist appears.
Before Karim and the others can act, these agents kill Rekka right in front of them, silencing him and cutting off a vital source of information.
Cooperation with the 8th Special Fire Brigade
Rekka’s death is a heavy emotional blow to Karim Flam.
He has lost not only a comrade but also a childhood friend, and the betrayal and tragedy leave a deep mark on him.
Witnessing the white-robed group and learning of the Evangelist’s involvement changes Karim’s perspective.
He realizes that the conspiracy behind the artificial Infernal incidents is far larger and more dangerous than internal corruption within a single brigade.
Determined to uncover the truth behind Rekka’s actions and the Evangelist’s plans, Karim decides to cooperate with the 8th Special Fire Brigade.
Although he remains part of the 1st, he offers personal assistance to the 8th, sharing information and lending his abilities to their investigation.
This alliance highlights Karim’s strong sense of justice and loyalty.
Even when faced with betrayal from someone close to him, he chooses to move forward and fight for the sake of both the living and the dead.
