The following page will have some ukagaka links I find useful or cool! That will include download sites, ghost archives, and shells.
Shells
- A page with links to sites with shells
Ghost Download Sites
- Nicely organized and has a lot of ghosts
The Ghost Center- The site hasn't been updated in a while and is in Japanese, but who knows what you might find!
Some Cool Ghosts
