sorry to post it twice, I didn't see your post.

The most incredible thing in this story : your 
#5 and #7 have the same winner. This guy has 
also bought 3 others CCS OP cels for more than 
200000 yens each this month ( see his history), 
not listed in your records. I let you calculate 
how much the total is O_o
And I'm not sure he is not the same guy than the 
buyer of #8, also higher bidder on the #3 cel 
last year I think.
