Intro — Kashimo, the Thunder That Outlived His Era

Four hundred years ago, before the world knew the name Kashimo Hajime, there lived an old warrior whose real name history has already forgotten. Age had weathered his bones, illness gnawed at him daily, yet none of it ever softened the storm in his spirit. Even at the edge of death, he was feared—because he never sought victory for pride, nor survival. He sought only a worthy opponent. And in an era where strength had thinned and true challengers had become rare, the old warrior grew bored of the weak and weary of a world without worthy foes.

That was when Kenjaku reached out.

With promises whispered across centuries, Kenjaku offered him what the world could no longer give: a place in the Culling Game… and the chance to fight Sukuna himself. For the warrior, this was not temptation—it was fulfillment. To taste either defeat or sweet victory, as he once put it himself, was the only wish that ever mattered.

And so, the old man accepted, binding his soul to the ritual that would one day bring him back.

Reborn Into the Culling Game

In the present age, his soul awakens in the youthful vessel named Kashimo Hajime, the name recorded by the Culling Game’s barrier as the identity of the body he occupies. Once revived, he entered the Game already bearing a significant number of points, earned through battles fought the moment he manifested—proof enough that his thirst for combat never faded with the centuries.

Alone in the chaotic killing fields of Shinjuku, he carries his staff over his shoulder, walking with the calm certainty of a man who has lived long enough to no longer fear consequence. He hunts for clues, rumors, any whisper that may lead him toward Sukuna. Because for Kashimo, the world is divided into two groups: those who bore him and the one opponent he has waited four hundred years to meet.

Until then, he walks his path quietly, lightning humming beneath his skin, a warrior reborn and restless in a world finally strong enough to challenge him.
