Corpse Doll

Corpse Doll is a Ninjutsu developed by Akame no Nishiki that the puppeteer uses to fake deaths or surprise opponents. When the opponent cannot see him after having launched an attack, Nishiki quickly unseals a human sized doll from a seal on his arm and focuses chakra into it. This lets it take the appearance of anyone he chooses and shows them dead by any injury he chooses. Nishiki then somehow dodges the attack, and leaves the doll behind. To an opponent it looks as if Nishiki has been killed, making him leave his guard down, when Nishiki can then launch a surprise attack on him.
