Naruto: In Konoha, System Arrives Twenty Years Early

[Chuunibyou System + Single Female Lead + Konoha + Uchiha] In Konoha, just born, oh wow, the system is here, and twenty years early! [Konoha Year 58, you are in the prime of youth, as the eldest grandson of the Uchiha clan elder. Though born noble, your talent is like a faint glimmer in the night sky, not even awakening the clan's iconic one-tomoe Sharingan, leaving a faint regret in this land where ocular power reigns supreme.] [On the night of the Uchiha clan's massacre, you awaken past life memories in the darkness, surging like a tide. But the light of awakening cannot reverse the situation; the enemy's blade is already upon you, and the moment of despair solidifies into eternal regret.] [Now, you are like a candle flickering in the wind, swaying at the end of fate. Looking back on your life, ordinary as a drop in the ocean, leaving no brilliance in the long river of Uchiha history, regret inevitably fills your heart. But at the final chapter of life, tranquility descends, and you realize that every existence has its unique value.] [The unyielding soul—how could it let life end hastily? At the critical moment of life and death, please awaken your inner strong will, grit your teeth, gather your last strength, and stand up. Challenge fate alone, rise up in resistance, and vow to create a legend.] [Accept mission? Yes/No] [Mission completion reward: Both eyes one-tomoe Sharingan] Uchiha Hayato, just born, is a bit dumbfounded: Did I come early, or did the system come early? Whatever, isn't standing up just something you can do with your feet? The mission... is it already complete? Just born, and already awakened the Sharingan?
