Card daemon

Card daemons (カードダイモーン Kādo Daimōn) are mysterious spirits responsible for the creation of ''Cardfight!! Vanguard'' cards. Whenever a card is generated by magical means, such as through a Depend Card, card daemons instantly carry out the creation of that card, illustrating its art and coming up with its card text. Card daemons are responsible for card balance, and always work to make sure that they cards they create would be balanced in a metagame, despite their users' lack of regard for a meta.

The card daemons were first brought together, by the demiurge, the true creator of Cray, although he did not create them. Like the demiurge, the card daemons are completely amoral and are only interested in telling good stories. If they wanted, they could easily solve all problems on Cray and Earth by giving heroes cards that said "[AUTO](VC/RC): When placed, you win", but they do not. Long ago, as part of the process of creating Cray i, Hazur convinced a few of the card daemons to work for him; as they are much more powerful than Hazur, it is unknown as to why they agreed, although like everything else, it is likely they thought that Hazur's creation would be "interesting."
