Silver Secret Technique: Creation of A Warring Demon

Akagi developed this technique before his defection from Sunagakure, it was the technique that transformed his art from Obsidian to silver. And it also lead to Sunagakure pushing his puppet mastery to legendary statuses. This allows him to turn humans into bionic puppets, or Androids. Based off of Nagato's infamous Asura Path, Akagi single handily pushed puppetry into a more futuristic field.

He begins by making the innards of his android which is beneath the skin. He places his targets heart and stomach into a jar to prevent decomposition. After, Akagi cleans out his targets body by draining its fluid and unneeded organs while removing their bones. He implants a metallic skeleton into their body, followed by their heart and stomach into two special compartments which are closed for protection. Their metallic skeleton are filled with secret compartments for various traps and weapons, including chakra based blasters. He finishes by closing the corpses by stitching together their skin and creating openings for his puppets weapons. Similar to Human Puppets, These puppets are different from normal ones, as they retain their use of chakra and any kekkei genkai or techniques that the human host once had. These puppets surpass puppets of Sunagakure due to their futuristic composition. However, the disadvantage is that it requires a lab to create. Which lead to Akagi having a reverse summoning scroll which brings him to his hidden lab.
