This Blue-eyes Ultimate Dragon Yu-gi-oh Card Is "one-of-a-kind"

And it's on sale for 45 million yen

Among the specialty shops in Akihabara is one particular store with a focus on rare, expensive trading cards. Card Shop Spiral regularly updates its wares, which can range from 200 yen booster packs to 120,000 yen English edition of the Black Magician Yu-Gi-Oh! card. But this isn't even the most expensive or rarest Yu-Gi-Oh! card in the shop.

That distinction belongs to the one-of-a-kind Blue-Eyes Ultimate Dragon. Twitter user Saku06 shared images of the card at the shop. This version was once the prize of the Asian Yu-Gi-Oh! Championship winner, as evidenced by the card's accompanying case. Only competition prize cards are sealed in custom-made cases.

The card also includes a signboard with a signature by Kazuki Takahashi, the original creator of Yu-Gi-Oh!. Saku06 was the previous owner of the card set and attempted to "sell" it for 99.9 billion yen (US$904 million) in 2016. Apparently there weren't any successful biters and the set is now at Card Shop Spiral for 45 million yen (US$400,000).

Since posting the images online, several commentors have reached out saying they'd like to go see the card set and snap picture.
