Synopsis: The Max Magic Level Great Sage's Return

Magic Level 99990000 Great Sage All-Attribute. Monsters began to appear all around the globe without warning. The sole individual capable of rescuing humanity from "The Calamity" was "The Great Sage Ichikami Atsumu." However, even though he found peace in death, he was reincarnated into the body of Kusanagi Minato, a boy who was bullied into taking his own life. Waking up in Japan fifty years later, Atsumu is astonished to discover a tranquil world where magic has considerably diminished since his time. For now, he opts to return to Kamui Magic Academy as Minato, only to discover that mages have become mere remnants of the past, replaced by a class of privileged nobles. After dismissing his low-level bullies who liked to boast, Atsumu captures the attention of a noble magician girl, Mizuha Yuika, along with his fellow students and teachers. Furthermore, Atsumu uncovers indications that the Calamity, which was believed to have been quelled, is set to return–– "It appears my power is still required." Within the soul of a student resides the Great Sage?! The mightiest Great Sage will alter this world that has grown complacent in its peace. With his reincarnation in the future established, the stage is set for a new Hero’s tale!
