Beelzebub aka Bee is a tall and slim fox-like demon with shapely hips, digitigrade legs, and insect-like features - such as two pairs of arms, a pair of antennae attached to her ears, and a small pair of insect wings which are light yellow with pink outlines. Her long hair and tail appear to be made of lava lamp fluid colored in bright pink, aqua-blue, and orange, with her waist also resembling a lava lamp. Atop her head is a pink, black, and white tuft resembling a small, flame-like crown. Her fur is light yellow with dark fuchsia stripes and small markings located on her ears, the sides of her face, and between her eyes respectively, with white from her upper torso up to her muzzle with a small black nose. She also has a dark fuchsia stripe on her head, which is shaped like a small heart. Her eyes have very pale yellow sclera and hot pink pupils, as well as faded light maroon upper eyelids and thick eyelashes with two protruding that resemble antennae. She also has black, dripping-like markings from her eyes, and over her four arms and digitigrade legs, resembling long fingerless gloves and thigh-high stockings. Beelzebub wears a black choker around her neck, a low-cut black top under a small and sleeveless, off-the- shoulder pink crop-top with lighter markings below the heart-shaped cutout, and a set of light pink shorts with the trim being the same color as her top. Beelzebub presents herself as a highly extroverted, energetic party girl who is optimistic, cheerful, loud, and welcoming. As a host, she maintains a lively atmosphere where guests can indulge in food and alcohol, including her Beelzejuice. Despite being one of the Seven Deadly Sins, she is laid-back and comfortable approaching strangers. She is also very expressive and prone to oversharing, as shown when she tells Loona about having a “rainbow in her...” and encountering a shirtless Satan. Unlike most of her fellow Sins, Beelzebub is sympathetic toward lower-class demons, including imps and hellhounds, even romantically involving herself with one. In “Mastermind,” she advocates for Blitzo, calling him “a real wildcard, but he’s a lot of fun” and insisting he deserves to be heard. She is competitive, as seen when challenging Blitzo to a drinking contest, but respects him when she loses. She genuinely cares about others’ wellbeing and dislikes self-destructive behavior. When Blitzo spirals after his bad date with Stolas, drinking heavily and making out with guests, she expresses genuine concern. Beelzebub dislikes disrespect and isn’t afraid to assert her dominance. When Loona insults her under her breath, Beelzebub uses her Full Demon form to intimidate her and warns her not to “mess with her.” She displays similar defiance when Mammon criticizes her and Asmodeus for associating with lower-class demons. However, she can recognize when she goes too far, apologizing to Vortex for nearly starting a fight with his friend. Ironically, despite being the Sin of Gluttony, Beelzebub is disgusted by Mammon’s messy eating habits, though her reaction may stem more from his poor table manners than his appetite.

Vortex aka Tex is a tall and muscular hellhound who, similar to Loona, sports a wolf-like appearance and a gray color scheme, only darker. He has a dog-like muzzle with a large black nose and sharp teeth inside, a bushy tail with dark gray tips, and black claws protruding from his fingers and toes. His fur is a few tones of gray, with his head and ears being colored in a rather dark shade of gray, along with a black, tattoo-like fur-pattern shaped like a wolf's head on his left arm. He also has thick black eyebrows and eyes with dark gray upper-eyelids - his right eye sports a bright red sclera with a white iris, while his left is blind and has a red scar across it, which also makes his left brow slit. Both his ears are slightly ripped. Vortex wears a ripped black cropped tank top under a dark gray leather jacket with rips on the hem and the sleeves being ripped off, along with lighter-colored lapels and red spikes on the front of the sleeves. He also wears a pair of ripped, dark gray knee-length shorts. As a bodyguard, Vortex is intimidating at first glance, but is otherwise very approachable and friendly with other hellhounds such as Loona. He's essentially a laidback guy who knows when to get serious, with a simultaneously laid back and no-nonsense attitude, especially when it comes to his job. He'll happily strike up a conversation with someone he can see means no harm but will not hesitate to knock someone out if they get too close to his boss. As the bodyguard and a friend of Verosika, he supports and protects her. In "Apology Tour", he sings along with Verosika about Blitzo being a "motherf*cker" as backup for Stolas, even though he never had any personal grudge or hatred against Blitzo.
