Reborn as the Strongest Archmage

Yuuto is dead. Officially, anyway. Unofficially, the Level 3299 SSS-Rank Archmage has been reborn into the world he saved a century ago—only to find his name erased, his guild in ruins, and his legendary achievements forgotten. The magnificent organization he once led now shelters a handful of struggling misfits. The realm he sacrificed everything to protect teeters on collapse, its magic systems degrading, its political structures corrupted. They think he's just a support mage with a few tricks. They haven't seen what happens when the Strongest of History starts learning again—copying any skill he witnesses, evolving it beyond recognized limits, fusing disparate abilities into something the System cannot classify. From Heal Boost to EX Heal Resonance. From forgotten legend to force that will reshape reality. As he rebuilds his legacy one unlikely ally at a time: a fire witch who keeps accidentally setting him on fire, a healer whose smile gets disturbingly bright in combat, and a fallen noble who decided Yuuto's goals should become his own. Between dungeon dives and party arguments, between political schemes and world-level threats, they'll prove that the strongest magic is the kind that raises everyone around you.
