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, 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.
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.
