This genjutsu requires the Sharingan and eye contact to be activated. The illusion traps the victim in a dark empty space where their body is made of paper that burns from toe to head while the user is watching. The purpose of this jutsu is to use the target's vision of their new form to reduce their dexterity, making it harder for the victim to battle or perform hand seals.
