Feri's brother, also known as the Khamsin, was said to be the greatest warrior amongst the Warriors of Kruga, who are themselves considered one of the strongest jaeger corps in all of Zemuria. Despite his cool and detached demeanor, Kasim makes it a point to never drop his guard. Along with his superior leadership abilities and the immense strength required to wield his giant, military-grade buster lance with ease, it's no wonder he has a reputation as the strongest jaeger in the world—in regard to combat, at least. Kasim is currently employed as the security chief of Marduk Total Security Company. However, two years ago, he also served as Van's instructor in combat. It was with Kasim that he learned how to make better use of both his stun caliber and his hollow style martial arts. Despite cutting ties with the Warriors of Kruga, he appears to be watching over his younger sister from afar as she attempts to become a warrior in her own right.
