Headscratchers / Princess Waltz

• Sometimes, Chris is shown with a protrusion out of her neck. (Typically, when she comments while she and Arata are in Iris's body.) What the heck is that?
  • Pretty sure that's just a flaw in the artwork.

• Chris was brought up isolated. How did he ever become an expert basketball player?
  • She can also speak eloquently, she knows a lot off history, she knows enough about Japan to more or less fit in etc. She had tutors in various areas, presumably sports was among them.
