The PV leaked on YOUKU:

EDIT : The short version was indeed a spoiler.... too bad
But the full PV is .... idk.... not that great.
The dance scenes was a great idea, but under-exploited, as usual... And the 'ink dance' is too long i think.
They could have made a great storyline, with such an ending, but they messed up again.
Masashi Muto on commands ? Fire him already Ayu... Bring back some Kouki Tange videos... PLZ
