Fai x Kuro-Pi
I recently picked up the Tsubasa Reservoir Chronicle manga out of curiosity (I was collecting XXXHolic at the time), and ... kinda fell in love with it.
I love all the characters, admittedly, but Fai and Kurogane's relationship makes me laugh. So I just had to draw something that represented how I saw them. :)
I wasn't intending to cel-shade it, but when I was putting down the flats in OpenCanvas, I decided that it'd likely look better, so did it that way.
