Kadokawa revealed more cast members for the anime of the poker-themed High Card multimedia project on Friday. The staff also previously announced the opening theme song artist. The new cast members include (Note: Character name romanizations are not official.):

Shunsuke Takeuchi as Brist Blitz Broadhurst, one of Norman's private secretaries and bodyguards. He is straight-laced, serious, and pragmatic to the extreme, constantly nagging Norman about overtime pay, hazard pay, and work regulations. He assists Norman in collecting cards, but has no passion for the cards himself, considering it strictly business.

Mie Sonozaki as Brandy Blumenthal, one of Norman's private secretaries and bodyguards. While seemingly calm to the point of nonchalance, she makes sure any job started is a job finished. She thinks Norman would be a good CEO if not for his obsession with the cards, and while this frustrates her, Norman nevertheless has her respect.

The band FIVE NEW OLD will perform the anime's opening theme song "Trickster."

Previously announced cast members include:

Finn will eventually learn what the shootout was about. The world order can be controlled by a set of 52 X-Playing cards with the power to bestow different superhuman powers and abilities to the ones that possess them. With these cards, people can access the hidden power of the “buddy” that can be found within themselves.

There is a secret group of players called High Card, who have been directly ordered by the king of Fourland to collect the cards that have been scattered throughout the kingdom, while moonlighting as employees of the luxury car maker Pinochle. Scouted to become the group's fifth member, Finn soon joins the players on a dangerous mission to find these cards.

"All you need in life are manners, dignity, and the will to bet on your own life."

However, Who's Who, the rival car maker obsessed with defeating Pinochle, and the Klondikes, the infamous Mafia family, stand in the way of the gang.

A frenzied battle amongst these card obsessed players, fueled by justice, desire, and revenge, is about to begin!
