Aiden Hoshino was the last survivor of an apocalyptic world consumed by demons, monsters, and chaos. Humanity had fallen, and despite gaining power through an enigmatic System that mimicked the structure of a video game, Aiden failed to stop the Cataclysm that wiped out Earth. Now, at the end of his world, facing the Demon Lord Morcath, Aiden’s life comes to a tragic close. But just as death embraces him, the System offers a final, impossible choice: “Reset the world.” Waking up five years before the Cataclysm, Aiden has been granted a second chance to change the future and save humanity—but with severe limitations. The System has regressed him to Level 1, wiping out his hard-earned abilities, and now, the timeline is different. Unforeseen enemies, new variables, and hidden quests loom in the shadows. As he struggles to rebuild his strength, Aiden soon realizes he is not the only one who has glimpsed the future. Other people, including old friends and rivals, may have access to their own System, and some have their own agendas. Faced with a countdown to disaster, Aiden must gather allies, uncover the truth behind the System, and fight against fate itself. But as the lines between friend and foe blur, and the world shifts in unexpected ways, Aiden starts to wonder if even this second chance is enough to stop the apocalypse.
