Naruto: Naraku's Shikon Jewel Devouring System

[Dark Villain Protagonist + System Power Fantasy + Naruto Fan Fiction]

[When Naraku, the ultimate boss of Inuyasha, descends upon the Shinobi World with the Shikon Jewel]

Core Premise]

After dying, Naraku is reborn in the Naruto world and awakens the "Shikon Jewel Devouring System":

- Devour and evolve: Absorb Kekkei Genkai and Tailed Beast Chakra, fusing demonic energy with ninjutsu.

- Corrupt and assimilate: Implant Shikon fragments in enemies, turning them into puppets.

- Build a power base: Establish "Yogakure," shelter rogue ninja, modify Jinchūriki, and forge a dark empire.

The light of this Shinobi World should have been swallowed by darkness long ago.
