Karim is a young man with short, straight dark grey hair, that is brushed towards the front, with the dark-colored hair at the sides being shaven. He has small and lazy dark eyes and is generally seen with an irritated facial expression. His outfit consists of a dark-colored 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 three Company Commanders of his brigade, instead of wearing bunker gear. Karim usually wears headphones, and, in combat, is seen wielding musical instruments.
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 his 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 Special Fire Force Company 1. 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 Hoshimiya and Foien Li.
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 from an external source inside the instrument, then transform the heat into sound, thus decreasing its temperature, and, by repeating the loop several times, creates ice, which can be launched at opponents or be used to incapacitate Infernals. In simplistic terms, Karim has compared his ability to how air conditioning functions. 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. Karim demonstrated the proficiency to think and come up with an effective plan in a very short amount of time, making him strategically adept.
VS. 1st Special Fire Brigade arc Edit
After the scuffle between the 5th and 8th Special Fire Force Companies, Karim, Rekka, and Foien are approached by Leonard Burns, and 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 Leonard. 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. Afterwards, when a Infernal was spotted in the Shinjuku District, Karim takes lead of a squad and incapacitates the threat. During the mission, Shinra spots a person creating a Infernal using artificial means and catches Karim and Rekka at the scene of the crime, but does not approach either of them about the incident. Later, Karim catches Shinra and Arthur in his room, where he informs them that the culprit behind the incidents is Rekka.
Karim notes that the situation regarding Rekka is to be handled by Special Fire Force Company 1, but specifies that, since Arthur and Shinra are not his subordinates, he cannot order the two to not get involved. A while later, Karim and Foien locate Rekka's whereabouts, where Karim immobilizes Rekka and encases his body in ice in order to stop him from further injuring Shinra and himself. After a flash of light illuminates the area, Karim and the group notice Rekka's body impaled, leaving him dead. Left in awe, a second arrow is fired at the group, catching everyone off-guard, followed by another arrow aimed specifically at Karim, but finds himself saved by Foien, who loses his forearm in the process. Quickly, Karim orders Shinra to create a smokescreen in the room to blind the snipers, and for Tamaki to extend her tails to intimidate the sniper, to which the plan successfully works. Soon after, the 1st calls Foien, alerting him that a gigantic Infernal has appeared in the Shinjuku area.
Preacher Pursuit arc Edit
Karim and Leonard, alongside the seven Battalion Commanders and Fire Officers of the Special Fire Forces, attend a meeting with Raffles III, where Adolla Burst and the issues involving the Spontaneous Human Combustion is brought up. After the meeting, he approaches Akitaru Ōbi and asks to work alongside the 8th, to uncover the truth behind Rekka while tracking the Preacher.
