NIS's Great Edo Blacksmith gets an opening trailer

Is this the Japanese answer to Spelunky? A old digger, mining the hills for the best metals to impress his girl with? Not quite, in typical Japanese fashion Great Edo Blacksmith looks more dating game than exploring, with no hint of the questing elements in this trailer. There are a few pics in previous stories, so don't get too worried yet.

Could the sexy element help sell this all new game, something of a rarity these days, or will it be another Vita here today, gone tomorrow release?
