Seventeen-year-old Takumi Satou never asked to be the universe’s janitor. He just wanted to buy a new game. Instead, a wasp sting killed him and triggered the afterlife’s worst glitch: a hiccup that fractured into five hundred centillion realities. By dumb luck, Takumi is chosen for "damage control." His job? Traverse absurd afterlife worlds, survive broken physics, and gather the Keys of Existence to unlock the Mortal Gate—where the so-called creator (“John Isekai”) may or may not be waiting. Armed with an Unlimited Inventory, Takumi stumbles through bizarre realms, dying over and over while collecting allies, enemies, and unanswered questions. Is he just cosmic janitorial staff—or is there meaning in the endless loop of dying and starting over? A parody and homage rolled into one, Total Death Repeatability blends fast-paced emotional beats, action-packed comedy, chaotic world-hopping adventures, and an existential bite—an isekai that knows the rules, then trips over them on purpose.
