Aquarian Age: Juvenile Orion/Orion no Shōnen spun off of a trading card game. No more do I know.

This one is one of three (The other two being one in Di Gi Charat and one in Skyscrapers of Oz) that either came with my Samurai Deeper Kyo original volume one with wooden box or from the stores Akadot Retail and AnimegamersUSA.
