Eikaishin Technique: Guardian Barrier

is a sealing technique that banishes a shadow being when called upon by the Eikaishin Technique: Shadow Call technique. It requires a great deal of chakra and life energy to forcibly banish the summoned shadow being. Once the technique is finished, the user falls into a deep sleep. It is unknown if the reason is due to chakra exhaustion or another factor.

The technique cannot be used to banish the shadow/human hybrids that are created through Eikaishin Technique: Shadow Birth due to the physical and emotional bond between the user and created being. As well, it is because they did not originate in the alternate shadow world.
