Naruto: My System Can Steal Bloodlines

Awakening as an orphaned civilian amidst the chaos of the Third Great Ninja War, Kenji's past life memories offer little comfort in the brutal Naruto world. His true cheat manifests as the 'Bloodline Assimilation System,' a terrifying power allowing him to not just master, but *absorb* the Kekkei Genkai of fallen shinobi. Beginning with the Sharingan of a shinobi he reluctantly 'salvaged,' Kenji, with his inherently cold and pragmatic demeanor, navigates a war-torn landscape. His objective: absolute power and unshakeable security, to forge a haven for himself and the unique individuals he collects. Yet, as he meticulously grows stronger, Kenji finds himself an unwitting pawn in a cosmic game involving ancient Otsutsuki threats and the shadowed will of the world itself. He must master his monstrous ability and confront the growing void in his own heart, or risk becoming another casualty in a world he seeks to dominate.
