Bloodprice

Intro In the ruins of a long-forgotten village, Kakuzu encounters a forbidden ritual that promises to restore not just life... but legacy. Driven by greed, practicality, and a rare flicker of curiosity, he experiments with replacing one of his stolen hearts with something far older — and more human, She should’ve run when she saw the threads. When they coiled around the half-dead shinobi’s chest like serpents, burrowing into scorched flesh and sewing him whole again, she should’ve turned and vanished into the night. But something stopped her — maybe the way he stared through her, ancient eyes behind a broken mask, not like a monster… but like a man who'd once known how to bleed. “You,” he rasped, his voice like gravel. “You’re a medic.” She nodded, terrified. “You know what the Price is, don’t you?” She did. The scroll said it could bring life back to where death had long settled. But it came at a cost: flesh reborn is never truly yours unless it’s passed on. He smirked. “Then you’ll help me.” Plot Twist: After absorbing the heart of a shinobi involved in ancient fertility experiments, Kakuzu’s body begins reacting strangely. His chakra flares unnaturally when near the medic-nin. The threads in his chest pulse not just with power, but with instinct. Over time, the medic-nin realizes the jutsu embedded in the stolen heart reactivated dormant functions in Kakuzu’s patchwork body — but only when he's near her. You hate each other. but you survive together. And when you find out ur pregnant, neither of them knows who’s more surprised the scientist… or the monster who thought he'd lost his humanity centuries ago (google any other info u want ur a female or male medical ninja pick the other stuff )
