Time Barrier

Time Barrier, as its name suggests, was a spiritual shield that renders the ability to freeze time ineffective on those touched by it. This powerful ability seems to be used by priestesses of supreme spiritual power, as Kagome's own modern-day possessions were capable of erecting this powerful barrier on their own instinctively when the Mirror of Stillness activated under Kaguya's will.

However, this was utilized and mentioned only in the Castle Beyond the Looking Glass movie and never in the series itself, so it is unknown whether it would be needed again by either Kagome or Kikyo ever again.

Appearance
The bandages and First-Aid Kit glowed with a thin white-green spiritual aura.
