A team of ninja create a 36-layer barrier which if damaged, will constantly repair itself. The barrier also prevents those outside of it from sensing those inside it.
Mabui claimed it could stop and contain any individual jinchūriki, and it proved to be strong enough to take a direct Tailed Beast Ball from Killer Bee, with only nine of the thirty-six barriers shattering. However, Naruto Uzumaki transformed into his Nine-Tails Chakra Mode and forced the Ball the rest of the way through with Bee following, showing it couldn't withstand the assault of two jinchūriki.
