Puppet Cannibalization

Puppet Cannibalization is a Ninjutsu developed by Akame no Nishiki that the puppeteer uses to fix his puppet body during battle. Should he become damaged, Nishiki will bring one of his puppets close to him, and then the parts of Nishiki damaged will be replaced by that puppet's parts. This means the puppet will be damaged and potentially unable to fight, but Nishiki can continue.
