At an American convention this past weekend, ADV (US) confirmed that they have licensed the following anime.<ul><span class=menu><li>Five Star Stories<li>Ghost Stories<li>Godannar<li>Onto the North (Kita e : Diamond Dust Drops)<li>Papuwa</span></ul>Along with these titles, ADV have futher signalled their intent to move into live-action distribution by also announcing that they have accquired six more live-action Korean features.

They might have also licenced Gilgamesh. Don't hold me too it.

I checked on the AnimeSuki.com licence database and apparently ADV licenced Gilgamesh back in July/August at the AnimeExpo convention.

Judging by the AnimeNFO page, it certainly looks original!
