Kamen Rider Den-O Trading Collection "Kamen Rider Den-O Sword Form" New Ensky Ultra-rare card. This is the card in the image. This is one of the phantom card series, as it was released suddenly with almost no prior notice, so many fans were unaware of its existence. This is the first card to kick off a great collection. Don't miss this opportunity. I am also listing other cards from the same series. Please take a look.
