One out of sixteen, but it's better than nothing! :D :D

I did "Inuyasha and Kagome" (or "Kagome and Inuyasha"..) today, it sounds nice but is very short, hope it is the one you're looking for! (I messed around with the transposing a bit to get it to work on the piano, combining two voices into the left hand and a few other changes, but it still sounds pretty good I think.)
