Naruto: Bloodline Completion System

Reborn as Nawaki Senju on the brink of death, he awakens the Bloodline Perfection System—his only chance to rewrite a doomed fate. In a shinobi world where the legendary Senju clan has been mysteriously disbanded and the Third Hokage schemes in the shadows, survival means more than just power. It means outlasting them all. No blind loyalty. No playing by their rules. With each bloodline perfected, he climbs toward the pinnacle of the ninja world, determined to fix the catastrophic mistakes of Hashirama and Tobirama—and ensure he's the last one standing.
