I was looking at the listing for these from Robby.jp (item code 10082542 if you happen to be a member) and noticed they list
Hasbro as the manufacturer. It may just be an a mistake - it seems strange that Hasbro would make a product for release only in Japan.
These look pretty neat and being blind boxed is cool which means that there will probably be a chase...
Methinks you're right. The listing at Robby describes them as follows: "
5 kinds items contains 12 pcs randomly". A box contains 12 pcs, and a carton contains 2 boxes (24 pieces). Perhaps one of the figures in the pic will be a chase...
