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 contact with the Ten-Tails' body, the beast is quickly absorbed into the human's own body. Usage of the technique causes the individual's hair to change colour, whether it be white or taupe, as seen in the cases of Obito and Madara, respectively. When absorption is completed, the user undergoes a transformation.

Trivia

 * Both Madara and Obito's appearance when they have control as a jinchūriki greatly resemble the Sage to the point where even his shakujō seems to be automatically recreated from the Truth-Seeking Balls.
