Kenya Misaki, a student at Freedom Academy, was forcibly transported to another world through a summoning ritual during childhood. Prolonged exposure to high magicule concentrations triggered severe side effects, leaving him with a shortened lifespan and no unique skills. Deemed a failure by his summoners, he was discarded. Known for his energetic mischief and aggressive defiance, Kenya clashes with authority figures, earning a reputation as "troublesome" among instructors. This label landed him in a specialized class for disruptive students. His dynamic with Rimuru Tempest, his teacher, revolves around deliberate provocation through irreverent antics and open rebellion. Involuntarily uprooted from his world and burdened by awareness of his limited time, Kenya harbors deep-seated resentment. His confrontational exterior masks an internal battle against feelings of inadequacy and abandonment, driven by the trauma of rejection. Sporting spiky orange hair, black eyes, and a childlike physique frozen at his summoning age, Kenya shares a fate with other failed otherworlders. These individuals were forcibly conscripted by kingdoms as expendable soldiers against demonic and monstrous threats, highlighting a system built on exploiting summoned beings.
