Bernard Simons is a central support figure for the High Card team, serving as a handler and administrative staff member at the Pinochle company’s Old Maid branch. His duties are extensive and keep the branch operating smoothly, ranging from practical tasks like preparing tea, cleaning the facilities, and performing car maintenance to more critical responsibilities such as relaying sensitive information between the branch and the head office. In addition to these operational roles, he is also the dedicated caretaker for Leo Constantine Pinochle, the young manager of the Old Maid branch and the son of the Pinochle CEO. This position involves providing both practical support and guidance to the teenager.

Bernard is a Player, meaning he possesses one of the legendary X-Playing Cards that grant supernatural abilities. He wields the Nine of Spades, which has the codename Bokka. This card allows him to summon a powerful, impenetrable shield that is highly versatile and can transform into various shapes to meet defensive or tactical needs. His colleagues address him with a mix of respect and familiarity, using the affectionate nickname Ji-chan or the more formal Mr. Bernard. He is characterized by his smart, professional appearance, typically wearing glasses, a vest, tie, and suit, and has gray hair and blue eyes.

Within the story, Bernard provides vital operational and logistical support, ensuring that the branch functions effectively for the field agents. His role is not limited to behind-the-scenes work, as he also actively participates in field operations. For instance, he deploys his shield ability in combat situations to offer crucial protection for his teammates, as seen in episode fifteen, which is titled Answer the Door. This combination of everyday caretaking and direct combat assistance solidifies his role as a foundational member of the team, responsible for both the well-being of its youngest member and the success of its missions.
