The Rebirth of strongest demon slayer in Jujutsu Kaisen

A long time ago, demons roamed this land. Terrifying maneating creatures, they knew neither pity nor mercy. And then the gods from Heaven decided to send down to helpless people someone who would help them defeat the powerful and merciless demon king. The strongest warrior who ever was, and ever should have been. And his name was Yoriichi Tsugikuni. But he did not fulfill his destiny, having missed the enemy of all mankind on that fateful night. Many years have passed since then, and Yoriichi himself turned into an old man who was killed by his own brother. But still, this man could have done much more... Cursed spirits, evil curse users, murderers and other scoundrels. So many innocents can still be saved from their vile hands!
