What Can Kotaku Tell Me About These Tales of Graces Vids?

Dear Japanese role-playing game gods, let Namco Bandai bring Tales of Graces to the US soon. I need to get the lingering yuck of Dawn of the New World out of my Wii.

Regrettably my Japanese has deteriorated so badly I have almost no idea what's going on in either video. However, I'm sure Tales fans will see a lot of familiar motifs to fill in the gaps. And of course you could argue that you don't need to be able to read the subtitles to know what's going on in a Tales game — the world is in danger, there's some elaborately-dressed individuals with fabulous, physics-defying hair, "OMG, don't kill yourself!" and so forth.

Seriously, sign me up. And please, take a stab at interpreting the text in these vids for me. Specifically, what's up with that sprocket the guy picks up during this gameplay vid:

P.S. BoA theme song for the win!
