The closest thing I've ever seen Kagome use as a barrier would be using her holy....
No no no wait, I remember now.
The third movie, Swords of an Honorable Movie, during the final battle, she used Sounga's sheath to put up a barrier, but I think it was mostly Saiya whom actually had the power of the barrier.
..powers to reflect Tsubaki's curse spell back at her. But I so want to say that I have Kagome's voice running around in my head saying "Gather around everyone, I'll put up a barrier..." from some episode or one of the movies...Gah!
