The Sealing Technique: Octopus Hold is a fūinjutsu unique to Killer B, using his ability to generate clones made of ink.


A fūinjutsu made for large military affairs, it can instantly seal up to 1,000 enemies. The clones, when they flank and entangle the enemy, begin to bind them. Within three seconds, the target's entire body is dyed by ink, completely sealing their movements; escape is impossible.[1]
