Yuya Shirasaki is a weak Awakened with no Natural Skill--a fact that causes his death in Earth’s final apocalyptic monster invasion in 2034. But when he opens his eyes again, he finds himself 10 years in the past and poised to use his knowledge of the future to save Arisa Miyanaga, a similarly weak guildmate. Doing so unlocks his Unique Skill, Akashic Records, which gives him perfect knowledge of any dungeon. However, the guildmaster of his old guild seeks to hasten a catastrophic monster attack, which Yuya must stop. Can he save the world this time around?
