The setting is a quiet suburban town where an ordinary high school student named Yuji has an unusual hobby of collecting Warhammer 40k miniatures. He spends most of his time painting and customizing his figures, and has earned a reputation as the best miniature painter in the area. One day, Yuji receives a strange visitor in his bedroom, and is shocked to find that it is none other than Death himself.

"Yuji, I'm tired of playing chess," Death moans. "Everyone always challenges me, and I always win in the end. I want to mix things up a bit this time." He points to the shelves filled with Yuji's meticulously crafted miniatures. "Let's play a game with these."

Yuji is hesitant at first, but Death offers him a deal. If Yuji wins, he will be granted a wish of his choice. If he loses, Death will take his soul. Yuji accepts the challenge and they begin the game.

As they play, Yuji realizes that this is no ordinary game. The miniatures on the board come to life, and he is suddenly immersed in a bloody and violent battle. The stakes are high, and Death proves to be a formidable opponent, unleashing powerful and deadly moves with ease.

Despite the odds against him, Yuji manages to hold his own, using his strategic mind and clever tactics to turn the tide of the battle. With a final stroke of his brush, he makes a daring move that leaves Death reeling.

Death concedes the game, and Yuji is granted his wish. Overwhelmed by the experience, he wishes to be able to bring his miniatures to life and live in a world where they are real. The wish is granted, and Yuji is transported to a world where he is hailed as a hero, and his miniatures are his companions and fellow warriors.

As he stands among them, he realizes that he has found his true calling. He becomes a master of strategy and tactics, leading his army of miniatures to victory after victory. And with Death by his side as a loyal ally, Yuji knows that he can conquer any challenge that comes his way.
