Magic Level 99990000 All Attribute Great Sage / Mahou Level 99999999 / 魔法レベル99999999 / 全属性大賢者

What happens when the greatest hero of the 20th century wakes up in a world that has forgotten how to be strong? Minato Ichikami was a legend, the Great Sage who sacrificed everything to stop the Demon God back in 1970. He died a hero, expecting his work to leave the world in good hands. But 50 years later, he wakes up in the body of a modern-day teenager named Minato Kusanagi, only to find that half a century of peace has turned the world’s magic into a joke.

The modern era is soft, complacent, and completely unprepared for the darkness creeping back into the shadows. Now, the strongest mage in history has to navigate the life of a high school student while the demon threat he thought he extinguished returns to claim the world once more. If the current generation is too weak to fight, he will just have to show them what a real Great Sage can do with his maxed-out stats. Forget everything you know about weak-to-strong tropes; this is a master class in absolute, overwhelming power. Get ready for an epic comeback where the ultimate veteran brings legendary force to a world that has lost its edge.
