"Huh?! Really?! Shouldn't I be a genius?" "Why did my divination fail?" Yagyu Yume, hailed as a genius diviner, issued a death prophecy to her classmate Inoue Sawa based on her intuition: "You will be seriously injured and hospitalized tonight, and you will likely die soon. Before that, say goodbye to your loved ones." But to everyone's surprise, Inoue Sawa not only survived unscathed but also miraculously escaped various life-threatening situations. He, who should have been reborn into another world to become a hero who saves a certain Western fantasy world, was reborn by mistake and ended up in a parallel world as Ritsumoto. To help Inoue Sawa successfully fulfill his mission, the Grim Reaper keeps bringing him back to life. Fortunately, he relies on his special abilities to make friends and encounters beautiful girls time and time again, repeatedly saving lives with their help...

An ordinary modern college student unexpectedly becomes entangled with a mysterious quantum force, forming a deep connection with his counterpart, Caesar, on the otherworldly continent of Atmura. A sudden, cross-dimensional connection erupts, and he is plunged without warning into this fantastical world—a land of warring states, where dazzling magic mingles with sharp swords, dragons soar and tear through the sky, and wondrous beasts lurk in dense forests and valleys. Every inch of this land is steeped in conflict and legend, completely overturning his understanding of the world.

A sudden crisis forces him into a perilous adventure. Left alone and helpless, he must rely on his modern knowledge to survive in a chaotic world overrun by magic. But his path is never smooth. He frequently confronts the continent's laws of the strong, becoming increasingly perplexed by the boundaries of good and evil: does the rise of the strong lead to rampant plunder and trampling of life, or to protecting humanity and ending war? Power itself is neither right nor wrong; it is the choices of the heart that determine the course of good and evil. This philosophical question leads him to pause and reflect repeatedly on his path to becoming stronger.

Meanwhile, the fog of fate constantly shrouds him, and he repeatedly questions himself: Is this transmigration a coincidence of quantum chance, or is it preordained? What is his mission in this world? Is it to drift along and eke out a living, or to shoulder an unknown mission and rewrite the world? Confusion and struggle intertwine, exploration and progress go hand in hand. When modern wisdom collides with ancient magic, when the confusion of mission clashes with the ambition to conquer, can he break through the shackles of fate, clarify the true meaning of good and evil, stir up the winds of change on the continent with his otherworldly knowledge, conquer nations, awe all races, and ultimately ascend to the summit of Atmura to become the new king who rules the era?

In the bustling tavern, a bard sang the legend of a dragon-slaying hero by the fire, while several adventurers gathered together to play monster cards. Mali finished the remaining capsule coffee in his thermos and said to the half-elf girl beside him, "Let's go, it's time to go," the kind waitress warned. "But there's a group of vicious snake-men bandits lurking on the road ahead. Why don't you wait a little longer? The Baron is already recruiting mercenaries." "No problem, we'll drive."
