Or rather "Daijoubu ka, atama no naka wa?" Inuyasha says this to Kagome after she asks him if he'll continue to protect her with Tetsusaiga. Bickering ensues ^_^;

I love their dynamic in the beginning of the series. They barely get along and it's very entertaining to watch.

I've found two sequence mates so far. I think I've seen others, but the thought of looking through all of the Inuyasha cels to find more makes my brain hurt XD

BakaInu has one here.

And Kagome-chan's Gallery has another two here and and here.
