Reverse Four Symbols Sealing

This technique is a sealing jutsu that Danzō placed over his body, setting it to activate upon his death. The jutsu releases four symbols from Danzō's body that then forms a large, black sphere around him. Anything caught inside the sphere's area is then drawn in and sealed within Danzō's corpse.

This jutsu has the opposite effect of Minato's Four Symbols Seal, a technique which allows Naruto to draw out the Nine-Tailed Demon Fox's chakra from within himself.
