In among all the shrieking of story ideas, it was decided that Vivi and Lewis are recently high school graduates rather than the fifteen years old that Kagome was. They’re travelling around for a year before they make decisions about college/careers when they end up going through the well.
Vivi’s modern outfit is a little closer to Daphne than Velma, though she’s already settling into what will be more her style as she gets older. Lewis–since he’s eighteen–is a little lankier than usual; his shoulders haven’t quite filled out and he’s still in the awkward stage of mid-growth spurt.
Arthur is just grumpy because he’s been bound by a plastic trinket.
(fun story: when they told me to make Arthur’s hair long and I shared the sketch, Skype randomly changed its language to Japanese. To quote Ecto: it senses the weeb.)
