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 go white, as seen in the case of Obito and Madara. When absorption is completed, the user undergoes a transformation and what seems to be the seal for this technique appears on their back. Madara's seal appeared as a circular design containing a ripple-like pattern with nine magatama, in three rows of three magatama each, beneath it. Obito's version instead had a larger magatama on top, which also had a ripple-like pattern within it.

Trivia

 * The design that appears on the user's back after they seal the beast resembles the one imprinted on the back of the Sage of the Six Paths' haori.
 * 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.
 * After gaining a portion of Hagoromo's power, Naruto's cloak gained the same magatama that appeared on all the Shinju's jinchūriki.
