Emily is a major character in the adult animated musical series Hazbin Hotel. She is a seraphim angel who is welcoming of newcomers

Emily is one of the younger Seraphims, yet she is full of joy and cares deeply for others.

Emily resembles a young girl with gray skin, long periwinkle hair with white tips, eyes light blue sclera and large, dark blue irises with no pupils, along with white freckles on her cheeks and the bridge of her nose. She has six white feathered wings on her back and has a white halo decorated with small, tiara-like spikes hovering above her head.

Emily is excitable, sweet, friendly, and kind to pretty much everyone. 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.

Emily also holds a great amount of sympathy towards human souls and sees them all as equal

Heaven is the ethereal realm of Angels. It is where souls go after their departure from life. But, unlike its infernal counterpart, Hell, Heaven is purportedly for the souls who are "good" and "redeemed", although the origin of Heaven and its native inhabitants has yet to be revealed.

The landscape is radically different from Hell and has an entirely different attitude.[1] Existing above Hell itself, Heaven can be seen in the Pride Ring's red sky next to the satanic star moon. At a distance, it appears to be a white orb with several rings around it and surrounded by wing-like clouds. At the surface, its atmosphere features clear skies filled with brilliant rays of light, while its terrain appears to be extensive fields of cloud.

Sealed by a giant golden gate, Heaven is a blistering paradise for those who were pure of good, allowing the souls to enjoy the luxury of everything opposite of Hell, and their forms were pure, guiding those who've been blessed with following the best interest of Heaven. However, deep inside, Heaven is a dystopia where citizens are completely oblivious to the Exorcists descending to Hell annually and reap various demons in an event known as the Extermination in order to curb Hell's overpopulation problem. Even when Adam and Lute outright inadvertently exposes the truth of the Extermination, many angels would try to deny their roles and turn a blind eye towards the event.

Aside from their roles in the afterlife, Heaven and Hell have a very hostile relationship in their roles with each other. Hell was created after Lucifer Morningstar and Lilith brought free will to humanity and evil entered Earth. After Lilith arrived in Hell, she thrived and allowed her to increase the powers of the Demons as more human souls arrive after committing sin. With Hell's power increasing, Sera, the Head Seraphim of Heaven, ordered the Extermination to happen so that Hell cannot rise up against them. In turn, the denizens of Hell hold strong animosity toward Heaven and its inhabitants for the yearly Extermination, with some planning countermeasures and defenses against the attack of Exorcists.
