This is a forbidden execution technique stolen from the catacombs of Kirigakure many years before the start of Naruto: Kimza Chronicles. Kaede Meitochi found it in a Shinziro hideout while searching for Otoshi Nagare and used it to defeat Shinziro member Hanna Tzuchki. It is stated that if the user's mastery of Water Release is high enough, they can draw all of the sweat and blood of the target all at once without heavy drain of their chakra. However, only kage-leveled medic nin with an affinity for Water Release are capable of such a thing.
