Demon Slayer: Invincible from the Start with Sun Breathing

A Sun Breathing swordsman who had once reached the summit was reborn, carrying four hundred years of sorrow and regret.

Given another chance, he resolved to rewrite the course of fate. This time, he would personally and patiently teach Tanjiro the full truth of Sun Breathing, devote all his strength to slaying Muzan, the lord of demons, end the disaster that had lasted for centuries, and cut off Muzan's head with his own hands.

He would tell his older brother himself: “You were never defective.”
