Shijou Saikyou no Mahou Kenshi, F Rank Boukensha ni Tensei Suru: Kensei to Matei, 2-tsu no Zense wo Motta Otoko no Eiyuutan

Twice-reborn, Aizawa Yuri has worn the crown of emperors across two separate existences—and he is utterly exhausted by the weight of absolute rule. Thrones, conquests, and the ceaseless demands of dominion have left him jaded, longing for something far simpler than godlike authority. Armed with the accumulated knowledge and abilities from his prior lifetimes, he secures a legendary reincarnation artifact, a tool that promises not power, but escape. With it, he severs his ties to the empires he once commanded and casts his soul into a world entirely unknown—a fresh realm untainted by his former glory. But even a blank slate cannot fully erase the echoes of two lives lived at the pinnacle of strength. Though Yuri hopes to embrace obscurity as a humble adventurer, the skills and instincts forged across centuries refuse to fade. In this new land, where magic and steel define the hierarchy, his very presence may prove too extraordinary to remain hidden. What begins as a quiet bid for freedom soon stirs the currents of fate, forcing him to confront whether a man who has already shaped two worlds can truly stand aside in a third. For Yuri, the greatest battle may not be against monsters or rivals—but against the legacy he cannot leave behind.
