It's the anime version of an Invisible Pet Fence -- when Inuyasha is a bad dog, Kagome resorts to the remote control faceplant! So much more effective than a rolled-up newspaper.

The background is definitely from Inuyasha, though I'm not sure if it's matching. I lifted a piece of Tetsusaiga off the background in Photoshop and put it in front of Inuyasha's hair, I think it looks better that way.
