Secret Art: White Corpse Technique

Using this technique, Yasaki Fūma managed to fake his own death by imagining a perfect copy of himself into reality, at an immense cost of chakra and energy. The copy acts like a dead body, suffering every natural changes in coloration, mass and odor until eventually decaying. It is impossible to discern if the corpse is a fake and the technique cannot be released by any means.

Trivia

 * This technique is not a clone technique, as it cannot be dispelled.
