Not fluently, I have told about my skillz earlier in some topic. I can read manga with furigana, play most games, watch anime without subs... but I can't write nor speak very well. So to put it bluntly, I know Japanese as long as I don't have to create anything by myself.

Hehe, sword mountain indeed. No, it's an old word that means something like "to appear" or "go forth"... eeh, just watch anime Onmyou Taisenki, they use that word all the time. "Byakko no Kogenta, kenzan!"
