I've made a list to help you guys put names to faces for the secondary characters here. If they were in the anime (with a few exceptions), then they're not here.
Spoiler for Lots of images:
THANK GOD Japanese people usually have a common way of writing names, or I would have gone crazy.

Yes, Ken-chan was the thing I thought of first when I saw Urashima. The Thanks Disk update has new scenarios, so there's a chance Kikyou does appear in CG's now. I'm pretty sure she has her own character sprite thing though.
I might go play a little bit more tonight, so stay tuned.
I didn't really feel like it tonight, but here are a few videos to hold you over for a little bit (will be very busy next week).
Game commercial - it got stuck in my head last spring when I started watching my anime, and it popped up again when I finished

Track from the first drama CD "Tou" (Fight) at Nico Nico. (I wasn't paying attention to the torrents then...so I missed them
