Sera Seraphim (banished)

Sera is presented as a kind and level-headed person who cares for those she interacts with and welcomes even demons such as Charlie and Vaggie. As a High Seraph, she takes her job seriously and acts as a guardian of order among the angels. This extends to her civil and consistent demeanor, as she appears annoyed when Charlie curses loudly in court. She prefers negotiation over violence when it comes to conflict, such as when she is willing to listen to Charlie about his plan to solve the overpopulation crisis in Hell. Sera also displays a caring side towards the angels she is devoted to, particularly with her fellow Seraphs, Emily, to whom she acts as a mother figure.

Due to her peaceful nature, Sera greatly disapproves of Adam's youthful and spiteful tendencies and the more violent and bloodthirsty of the 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 massacre in the upcoming Extermination. Sera considers his actions to be unnecessary and disapproves of Adam's delight and bloodlust in doing so.

Despite her gentle nature, Sera's steadfast dedication to stability and willingness to do whatever it takes to protect Heaven from chaos leads her to take controversial actions. This even motivated her to support the annual extermination of Adam. Her care for the other angels also influences these decisions, fearing that the same outcome that befell Lucifer would happen to Emily and other angels if they questioned Heaven's methods, even going so far as to shield Emily from the truth in order to ensure her happiness.

Sera's appearance is that of a tall, slender woman with cedar brown skin, white freckles and a white stripe running down her nose, and hip-length curly silver hair.

Her eyes have white irises, blue-gray sclera, deep purple pupils, and thick, deep purple eyelashes protruding from them. Above her eyelashes are a pair of holographic-looking eyelashes, which are colored in a slightly paler shade of deep purple. She also has six feathered wings that are pale periwinkle in color, and white on her back, a white halo decorated with large crown-like spikes and blue gem-like circles, and a second halo hovering over the first.

For attire, Sera wears queen-inspired clothing consisting of a two-layered periwinkle-grey dress with a pale periwinkle collar with high ruffles, white puffed sleeves, and periwinkle-grey with white detailing, along with most of the bottom and hem being pale periwinkle and white with diamond designs around it.

Sera was banished because of her actions as she made decisions that were not in accordance with the rules of heaven.
