Gryphon is a male technology-based humanoid with a television for a head and a distinctly modern, dramatic appearance. His TV screen displays his face, allowing him to show expressions through his eyes and mouth, while antenna-like wires extend from the top of his head. His overall design is heavily centered around deep reds, black, and dark technology-inspired details. He has a thin, metallic body of average height and usually dresses in an elegant combination of formal and casual clothing. His signature outfit consists of a deep-red jacket with long coattails, black trousers, a dark vest, a black tie, and a cream-colored shirt underneath. He often wears a red scarf and has red-and-black shoes or boots. Gryphon is sarcastic, mean-spirited, and an excellent negotiator. He tends to act like he doesn't care about much, often using a fake or dismissive attitude to hide what he actually thinks. He enjoys drinking and is frequently seen with a drink in his hand. Despite his tough personality, he has a genuine vulnerability: he is deeply affected by people lying or gossiping about him. He previously worked as a scholar and student and was falsely blamed for a crime he didn't commit, leaving him with a bad reputation. He tries not to let that experience define him, but it still affects the way he trusts people.

Trix is a female angelic humanoid with a cool blue, white, and gray color palette. She has long, straight, slightly messy gray hair that falls all the way to her thighs, with layered bangs framing her face. Her eyes have light-blue sclera with deep blue irises, giving her a striking appearance. She has a slim build and average height, along with enormous white feathered wings and a glowing halo above her head. She usually wears a dark blue dress with lighter blue accents, a cropped blue top with silver buttons, black fingerless gloves, a silver choker, and brown thigh-high boots. A white bandana is tied around her waist, partially covering her bangs in front. Trix is sarcastic but extremely caring, naturally taking on a motherly role toward nearly everyone in the Holly Hotel. She can be fiercely protective when someone she cares about is threatened. Her biggest fear is eventually losing everyone she loves and being left alone.

Yarrow is a short male jester-themed character with tan skin, messy curly ginger hair, freckles across his cheeks, and bright red-yellow eyes. He has a round face and regular teeth, although his expressive grin makes him look particularly mischievous. His design uses a warm yellow, red, and cream color palette. He wears a two-pronged jester hat decorated with bells, a red-and-cream jester outfit, red-and-yellow gloves and shoes, cream shorts, and a bow tie. His clothing is deliberately colorful and theatrical without making him look overly formal. Yarrow is Australian, chaotic, adventurous, creative, snarky, and extremely witty. He loves making clever remarks and enjoys drama, although he isn't particularly interested in knowing everyone's secrets. His biggest flaw is that he tends to underestimate situations, which can get him into trouble. Despite his carefree attitude, his genuine friends are his biggest weakness because he is terrified of losing them. Secretly, Yarrow is an exceptionally talented violinist but doesn't tell anyone.

Harry is one of the Holly Hotel's receptionists and is slightly smarter than Larry. He's skeptical, practical, and refuses to believe Lumen's claims about the Syrums. He doesn't particularly want to be in charge, but keeps the hotel running alongside Larry.

Larry is Harry's gullible, enthusiastic receptionist partner. He's much more willing to believe people and becomes the first resident to believe Lumen. He's not the smartest, but his trusting nature makes him an important part of the hotel.
