Pipoya materials and CC

Hey, I was wondering if anyone who can read Japanese (and possibly who has a better gasp on the intricacies of the various RPGMaker/Wolf licenses) can clarify if this website actually says what I think it says. The Creative Commons link on this page, and the accompanying charmingly-translated "There is no limit individual and corporate, for-profit and non-profit use." seems to imply that the material's free and clear under an Unported license, but I've been bumfuzzled before and I'd like to know where I stand before inadvertently biting someone's rhymes. That said, this is some pretty awesome-looking stuff, so if we're cool I'll post it under art.
