Kai, a desperate Japanese gangster on the run from the law, is thrust into a wholly alien realm when he steps into Professor Hirabayashi’s experimental machine. One moment he’s on Earth, the next he’s naked under Kigen’s glaring sun. Immediately confronted by a hulking orc who shockingly speaks fluent Japanese, Kai’s street-honed instincts kick in—he lashes out, defeating the brute before fleeing into the wilds. Stranded in a rugged hill country populated by bizarre predators and roving orcs, Kai endures a harsh struggle for survival. Every day tests his limits as he scrounges for food, battles deadly beasts, and barely escapes hostile orc patrols. Yet he adapts fast. His body hardens, his senses sharpen, and a primal ferocity replaces the controlled violence he once used in Tokyo’s back alleys. Strangely, he feels a raw freedom in this lawless land, even as he teeters on the brink of life and death. Despite the constant threat of annihilation, Kai can’t ignore the unsettling mysteries of Kigen. How do orcs speak such impeccable Japanese? Why are some of their weapons so finely crafted? With no chance of returning home—and no desire to face Earth’s prisons—he presses onward in search of answers and safety. Eventually, he emerges from the hills to behold an imposing walled city rising against the twilight. Its architecture suggests both civilization and danger. Now, clutching a stolen dagger at his side, Kai steels himself for whatever lies behind those towering walls. He may be battle-scarred and half-feral, but his will remains unbroken. Once known as a brutal mob enforcer, Kai senses his story in Kigen has only begun. Driven by survival, curiosity, and a fierce refusal to surrender, he strides toward the city’s looming gates, ready to shape his new fate—or be shaped by it. ***Brutal Mobster Escapes to a Savage Another World is a fully self-contained fast-paced novella which pays homage to the classic Burroughsian-style of Portal Isekai, and which aims to be consumed in a single sitting by the reader.
