Naruto: I Founded a Jujutsu Clan

I, Zenji, woke up in the middle of a battlefield during the Third Great Ninja War. My only cheats? A complete knowledge of Jujutsu Kaisen burned into my mind, and two soul-bound treasures. I soon discovered a fatal flaw: for my Earth body, refining chakra was a slow form of suicide. But I just smiled. With Reverse Cursed Technique for self-healing and the Incarnation secret art to switch bodies, I possessed something that even Orochimaru would kill for. Using my knowledge, I created two ultimate trump cards: a "Gojo Satoru" with his Six Eyes bloodline and localized Limitless technique, and a "Sukuna" with a Wind and Fire Style Malevolent Shrine. The Hyuga clan claimed my Six Eyes was a stolen bloodline? I let 'Gojo' handle them. It didn't take long. My ultimate goal is not just to survive. I will use my treasures to re-establish the power of Jujutsu in this world, creating a new branch of power rivaling chakra itself. And my final target? The Chakra Fruit of the Ōtsutsuki! — Description from novelcodex.org
