Adamantine Sealing Chains

This technique moulds the user's chakra into chains which, after materialising, can be used for various purposes such as physically restraining targets.

When using this in conjunction with her special chakra, Kushina was able to restrain Kurama, the Nine-Tailed Demon Fox, in Naruto Uzumaki's mind. These chains also made up her seal, completely pinning the Nine-Tails down with several spikes in her mind. Even while near death, Kushina was able to use these chains in the physical realm to restrain the Nine-Tails, enabling Minato to use the Dead Demon Consuming Seal. This involved five chains emerging from her back and burrowing into the ground, after which they would surface and criss-cross multiple times over the target, holding them down.
