True, but Kurogane and Fay are also not that far in TRC, and yet they can be adapted well. I think the character designers shouldn't try to make the HOLiC crowd exactly like the manga counterparts. With a normal body build and keeping the faces/hairs, it could still work. They do it in other adaptations all the time. they can take liberties in hair colors and yet they keep the anorexia? fail

(oh, actually that doesn't sound bad at all! the teacher and his family are already spot on Watanuki XDDD)
