Naruto: Assassinating Minato Namikaze at the Start

Konoha, the Ninja World. Uchiha Sage, arriving just in time for the last train, stumbles upon the ring-wearing old man at the start of his journey. Then he receives the script of a ruthless, ambitious ruler. He awakens a system called the Scales of Fate. As a discarded pawn, Sage unhesitatingly places his Sharingan on the scales. He might as well not be an Uchiha. Release techniques, bloodlines, life, soul, loyalty, betrayal, annihilation, ideals… In this world, what is not worth trading? I will ultimately place you all on the scales and weigh the capacity of this ninja world!
