Parasoul is the crown princess of the Canopy Kingdom and the leader of the elite Black Egrets military force in Skullgirls. Standing tall with long crimson hair, she wears a sleek black mini-dress and thigh-high boots, striking a regal yet battle-ready silhouette. Driven by a fierce dedication to protect her younger sister Umbrella and her kingdom, she fights to destroy the Skull Heart and prevent anyone from repeating her mother's tragic fate of becoming a Skullgirl. In combat, Parasoul wields her living weapon, a sentient umbrella named Krieg that can summon explosive napalm tears, alongside a concealed Luger pistol and tactical support calls to her soldiers. She plays as a methodical zoning and space-control character, using her traps, long-range poke attacks, and military assistance to dictate the flow of battle while keeping opponents at a distance.

King Franz Renoir is the former authoritarian monarch of the Canopy Kingdom, husband to the late Queen Nancy, and father to Parasoul and Umbrella. A harsh, militaristic ruler who led his nation through the Grand War, his heavy-handed reign severely restricted political freedoms, prioritized ruthless weapons development, and suppressed domestic dissidents. Despite his oppressive policies, he cared deeply for his family. ​During the climax of the Grand War, when his wife was corrupted into the ultimate Skullgirl after wishing for peace on the Skull Heart, Franz sacrificed himself to blast her down using a powerful Living Weapon umbrella. Though long presumed dead, later story events reveal he mysteriously survived as a headless, flame-skulled entity bound to his living weapon, stripped of his former humanity and keeping out of the public eye.

Queen Nancy Renoir was the former ruler of the Canopy Kingdom, wife of King Franz, and the mother of Parasoul and Umbrella. Unlike her aggressive, war-seeking husband, Nancy was deeply compassionate and sought peace above all else, often praying at the Grand Cathedral to end the Grand War. Driven by a desperate desire to protect her people, she made a wish on the ancient Skull Heart for total peace between the warring nations. Because her wish harbored hidden impurities, the Skull Heart corrupted her, gradually turning her into the most destructive Skullgirl in history. Ironically, her wish for peace was granted only because her terrifying, monstrous transformation forced the warring world powers to unite in order to stop her. In battle, she wielded "Todd," a Living Weapon shaped like a scythe-umbrella that represented Death, complement to the apocalyptic theme of her family's weapons. She was ultimately killed by her husband using his powerful weapon, leaving behind a tragic legacy that led Parasoul to dedicate her life to destroying the Skull Heart. Visually, she shared a strong resemblance to Parasoul with long dark hair, elegant regal gowns, and a prominent cross necklace before her monstrous descent.

Adam is a loyal, laid-back officer of the Black Egret military force in the Skullgirls universe who fights using a giant wrench and heavy artillery. Serving directly under Parasoul as a member of her elite guard, he acts as a dependable right-hand man with a relaxed personality that contrasts the high-stakes conflict around him. In battle, he appears as a summonable assist character for Parasoul, driving in on a motorcycle, throwing wrench attacks, or providing cover fire to control space on the screen.

Molly (Molly Castle) is a supporting character in Skullgirls who works as a field communications operator for the Black Egrets. She appears alongside Parasoul in battle, wearing a signature communication headset, glasses, and a orange hair cut with long bangs. As a non-playable assistant character in the game's story and Parasoul's special moves, she provides tactical air support, radio call-ins, and logistics during fights with a playful, energetic personality.
