Reverse Four Symbols Sealing

This technique is a fuinjutsu that the user places across their chest, and sets it to activate upon their death. The technique releases four symbols from the user's body that then form a large, black sphere around them. Anything caught inside the sphere's area is then drawn in and sealed within the user's corpse.

Trivia

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