It's Chihiro and Sampson on a rooftop!

Chihiro is Bonehead's girlfriend. She lives in Tokyo, Japan (thus the stylized change of appearance), and has a guardian dragon named Sampson. She also plays guitar, works in a cafe and is a bit of a pop singer.
...If you can't already tell, I literally tried to make it so that she was incredibly stereotypical of your average anime character. SUCCEEDED.

Anyways, I haven't really had the chance to use her in an animation quite yet, but she's an important character, so sooner or later expect to see her.
