Card~Jitsu Language

I have noticed a language for Card~Jitsu. I call it Cardaness. This language could ulock something. I also noticed the dojo has a underground cave. The amulate has a code around it. The code is Cardaness. It could unloc the underground cave.

Blog Ninjas look at the code figure out if it unlocks something.
