Naruto: The Chakra Parasite

When a bored office worker dies in the modern world, he expects nothing but eternal nothingness. Instead, he awakens in the Naruto universe— not as a shinobi, not even as a human, but as a microscopic parasite clinging to someone’s chakra network. At first, he’s powerless, feeding only on scraps of chakra like a leech. But he quickly discovers his terrifying gift: he can borrow skills, memories, and jutsu from any host he inhabits. The stronger the host, the stronger he becomes.
