Daigo

Not much is known about Daigo except that he is famous for being a "legendary fighter". Daigo is a playful character and stands up for justice. Daigo uses a Royal Paladin Deck.

[Spoiler] In the anime, he is trapped in a space-time warp (as a side effect of the Royal Paladins' sealing). [/Spoiler]
