Kaiten no Albus is a unique fantasy series about a hero named Albus, who possesses the power of a time loop that sends him back to the very first day of his adventure every time he dies. With this ability, he struggles endlessly against fate to save the world and protect his companions. Although Albus has defeated the Demon Lord dozens of times, his victories always end in the same tragic outcome—his beloved companion Fiona is transformed into the next Demon Lord. Trapped in this cycle of despair, Albus desperately searches for a way to break free. Each loop sees him attempting the “fastest” and most “efficient” path to the Demon Lord’s defeat, employing new allies and strategies. Yet, no matter how many times he tries, he cannot change the fate of “defeating the Demon Lord = losing Fiona.” As the story progresses, Albus’s true goal shifts—from merely slaying the Demon Lord to preventing Fiona from ever becoming one. He begins to face the bonds of friendship, sacrifices, and countless choices with greater determination. Choosing detours, unexplored routes, and new methods, he fights to carve out “different futures,” chasing a hopeful tomorrow with his comrades. Blending time-loop suspense with dark fantasy adventure, Kaiten no Albus is a gripping tale of “super-fast repeated journeys” filled with tension, strategy, and emotion.

After sacrificing his life to save some students, he dies in an accident—only to be whimsically reincarnated by a god into another world, stark naked.

Fighting for his life against goblins and hobgoblins, he gradually learns how to secure food, shelter, and the means to survive. As he joins adventurer parties, clashes with villagers and nobles, and faces colossal monsters, Nozaki steadily earns a reputation as “The Wild Man.” Each battle, each decision to help his comrades, reinforces his identity as a lone yet dependable fighter.
