Shijou Saikyou no Mahou Kenshi, f Rank Boukensha ni Tensei Suru ~ Kensei to Matei, 2 Tsu no Zense o Motta Otoko no Eiyuutan

After countless lifetimes of ruling empires and wielding immense power, the legendary magic swordsman known as Aizawa Yuri has grown weary of his endless cycle of rebirth. Having lived two extraordinary existences—once as a peerless sword saint and again as a master of dark arts—he now seeks simplicity. Using forbidden knowledge from his past lives, he obtains a mystical relic capable of granting true rebirth. With this artifact, he abandons his former glory to begin anew in an unfamiliar world, free from the burdens of destiny. No longer bound by titles or expectations, he steps into this fresh existence with the wisdom of ages and a desire for an ordinary adventure. Yet, fate may have other plans, as his unparalleled skills and past experiences refuse to stay buried. Will this third life bring the peace he craves, or will destiny once again pull him toward greatness? The journey of a man torn between escaping his legacy and embracing his extraordinary potential begins anew.
