Species: Seraphim Angel

Sexuality: Bisexual

Gender: Female

Age: Older than the Earth

Appearance: In her humanoid form, Sera takes the appearance of a very tall and thin woman with cedar-brown skin, black lips, white freckles, and a white streak going down her nose. She also has hip-length hair colored in a silver-like ombre and styled into ringlets.

Her eyes have white irises, blue-gray sclera, dark purple pupils, and dark purple thick eyelashes projecting from them. Atop her lashes are a pair of longer, holographic-like lashes, which are colored in a slightly paler shade of dark purple. Her eyelids are colored like her holographic-like lashes.

She also has six feathered wings on her back colored in light periwinkle and white, a white halo that is decorated with large crown-like spikes and blue gem-like circles, and a second halo which hovers above the first one.

Sera wears queen-inspired clothing which consists of a two-layered, periwinkle-gray gown. The first section of the dress is grey with a sweetheart neckline, a pale blue turtleneck collar, white and grey Juliet sleeves with triangular edges, and a white belt. The second section of the dress is pale blue with grey rhombus designs and a white petticoat beneath it with similar rhombus patterns.

Appearance: Sera comes across as a kind, level-headed person who is caring toward those she interacts with and welcoming to even demons such as Charlie and Vaggie. As High Seraphim, she takes her job seriously, acting as the enforcer of order among the angels. This extends to her abiding civil behavior, as she seems upset when Charlie loudly curses in the court. She holds a preference for negotiation over violence when it comes to conflict, such as when she is willing to hear Charlie out on her plan to resolve the overpopulation crisis in Hell. Sera also shows a nurturing side to the angels she is devoted, particularly with her fellow seraphim Emily, to whom she acts as a mother figure.

Due to her peaceful nature, Sera greatly disapproves of Adam's juvenile and spiteful tendencies and the more violent and bloodthirsty of Exorcists, such as Lute. This is shown when Sera disapproves of Adam's declaration of targeting the Hazbin Hotel as the first area for him and his Exorcists to slaughter in the next Extermination. Sera deems his actions as uncalled-for and disapproves of Adam's delight and bloodthirst at doing so.

Despite her gentle nature, Sera's firm dedication to stability and willingness to do whatever it takes to protect Heaven from chaos leads her to perform controversial actions. This even motivated her to allow Adam's yearly Extermination. Her care for the other angels also factors into these decisions, fearing the same outcome that happened to Lucifer would happen to Emily and other angels if they questioned Heaven's methods, going as far as to protect Emily from the truth to ensure her happiness.

Appearance: In her humanoid form, Emily takes the appearance of a tall and slim young woman with silvery skin, black lips, and mid-thigh-length hair with bangs styled in a somewhat layered way, colored in a gradient of periwinkle with noticeable white tips.

Her eyes have light blue sclera with white-outlined darker-colored pupils and bushy, dark indigo eyelashes, and her eyelids are perano-colored, while her three freckles are white and are located on each of her cheeks and her nose. She also has six white feathered wings on her back and a light blue halo decorated with small, tiara-like spikes hovers above her head.

Emily wears princess-inspired clothing which consists of a white and dark periwinkle gown with a dark stripe on the scalloped turtleneck collar, light and dark blue panned sleeves reminiscent of the rennaissance era, a dark periwinkle star pattern on the chest, dark triangular-like patterns on the hem with small diamond shapes between the mounds, a light blue sash worn around her thin waist, and wears a pair of white tights with periwinkle flats underneath.

She also wears a set of long fingerless, periwinkle-gray opera gloves.

Personality: Emily is excitable, bubbly, sweet, friendly and kind to almost everyone around her. She does not discriminate others based on mistakes or who they are, where she excitedly greeted Charlie and welcomed her to Heaven, despite her being a demon. She compliments Sera in personality, with Sera the most serious and Emily the more bubbly. Working alongside Sera, her job is to preserve the happiness and joy of the human souls that ascend to Heaven.
