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.   ~!In the anime, he is trapped in a space-time warp (as a side effect of the Royal Paladins' sealing).!~  [Source: Cardfight!! Vanguard wiki]

Aichi and his friends have won the National Tournament and decide to go their own ways until a mysterious boy named Takuto Tatsunagi appears. He reveals that the Royal Paladins, Shadow Paladins, and Kagero leaders have been captured, and the only way to free Cray is for the Vanguard fighters to use a new power- Limit Break. Because the Royal Paladins lose the ability to fight, Aichi's deck is changed to be a Gold Paladin deck. Aichi and his friends must now win the Vanguard VF Circuit if they are to learn more about the occurrences on Cray and free their old friends.

A few months have passed since the VF Circuit, and Aichi is now in High School. However Aichi is in a different high school than most of his friends, a high school where the instructors focus on looking towards the future. One day Aichi admits he thinks Cardfight can be a future people can believe in, but in order to prove it Aichi must use his new deck, a deck in which Royal Paladins and Gold Paladins are combined as one force. Slowly but surely Aichi must gain friends through Cardfighting and help his new team win the newly formed high school cardfighting championships.
