Just finished Ghost Slayers Ayashi. Like I said, I just got the 3rd part of the series, since I had seen the first 2 all ready (and I used to own them).
It's an odd show dealing with loads of monsters, I think I may have goofed in calling them "Yoei" (that's what it sounds like they are saying), I think it's supposed to be Yomi.
Kind of has a bit of "giant monster" stuff going in a couple of episodes. However the ending is really annoying, since it's basically a "reset" ending (IE it goes back to the beginning of the show).
Might be worth a rental if you can find all of it (it's an Anime Legends type set now). Usual Bandai dub with the usual California crowd. BTW that thing I mentioned about Vic Mignola being in it seems to be due to him moving to California (and he has been in a couple of other Bang Zoom shows), which apparently irritated some fans. He is coming back to Texas to do the Fullmetal Alchemist Brotherhood movie dub.
