I took part in it with a very short comic featuring the Battle of Okehazama, trying to render the charisma of Nobunaga in those fateful hours.
I managed to get a few copies for friends through Teap, I'll make sure to review the whole thing and to offer a free "scanlation" of my contribution as soon as I get the volume in my hands!
If you're interested in the purchase, you can get a copy through Toranoana. The website doesn't offer a shipping service for foreign countries, but you can still get one through Tenso.com services :D
