The sealing technique used by Obito and Madara Uchiha to seal the Ten-Tails in themselves, making them jinchūriki of the beast. After performing the necessary hand seals, while in contact with the body of the Ten-Tails, the beast is rapidly absorbed into the body of the human being. Once sealing is completed, the user enters the Wise technique of the Six Paths. When Obito used this technique, his hair turned white.
In the anime, when Obito sealed the ten tails, a circular surrounding his body shield broke since the transformation was complete.
