Six Paths Ten-Tails Coffin Seal

The sealing technique used by Obito and Madara Uchiha to seal the Ten-Tails into themselves, becoming the beast's jinchūriki. After performing the necessary hand seals while in close proximity to the Ten-Tails' body, the beast is quickly absorbed into the user's own body. Once absorption is completed, the user undergoes a transformation. When Obito used this technique, his hair permanently lost its colour, remaining white even after the Ten-Tails was extracted from his body.
