Six Paths Ten-Tails Coffin Seal

The sealing technique used by Obito Uchiha to seal the Ten-Tails into himself, 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 Obito's own body. When absorption is completed, Obito's skin shatters apart and he takes on a unique form. What seems to be the seal for this technique appears on Obito's back as ten magatama: at the top is a larger magatama, with a ripple-like pattern within it, and nine smaller magatama, in three rows of three magatama each, beneath it.

Trivia

 * The design on Obito's back after he sealed the beast resembles the one imprinted on the back of the Sage of the Six Paths' haori.
