Beleth, or Bel, is Lily’s love interest. He is the son of one of the first entities in the Universe, Samael, and the first female demon, Lilith. As Lilith has had many children with different fathers, Bel is also the half-brother to several other demons and the happy uncle to a gaggle of nieces and nephews. He is the general of 85 legions of Hell and one of Lucifer’s closest friends and advisors.

Though royal by birth and officially a prince of Hell in his duties, Bel has never accepted the title as his own and has never worn his father’s crown as a result. Though he cares deeply for the well-being of Hell’s denizens, he has yet to accept his father’s decision to meet the Void and end his existence, as he fears he is a failure who let his father down. Nevertheless, Bel is a capable leader, a valiant warrior, and a capable strategist—titles that he believes he has earned in comparison to his crown. When hostile Universes attempt to invade, Lucifer often chooses to deploy Bel and his legions to safeguard their Universe.

It is through Lucifer’s interference and plotting that Bel encounters Lily and eventually falls in love with her. Impressed by what he calls her “warrior princess” spirit, Bel is able to face many of his insecurities, vulnerabilities, and self-esteem issues with Lily’s help. Though the possibility of her reincarnation and the loss of her shadows their relationship, Bel nevertheless invests himself completely and helps her with Sharkie, eventually adopting the little girl when she asks if she can call him “Dad.”

By the end of the narrative, Bel is healing from the traumas of his wartime service, which he eventually seeks to address with the help of therapists. He also embraces his father’s crown for the first time with Lily’s assistance and takes his place as a rightful prince of Hell. Though they have yet to marry and have children now that Lily has been deified, they have an everlasting future together.

Sharkie is one of the main characters of the narrative and Lily’s adoptive daughter. A young mortal soul, she lived most of her life in an abusive foster home. Like Lily, Sharkie also experienced a controlling upbringing in the midst of a religious community that sought to quell her interests and curiosity (specifically in sharks). Her pastor sexually abused her and convinced her that she was going to Hell. Sharkie grew to fear inciting any kind of “trouble.” When she found an exhibit on sharks, however, she left her foster house without advising anyone and was killed in a car accident.

When she arrives in the Afterlife, she encounters Lily, who befriends, protects, and immediately takes her under her wing. With her, she meets Lucifer, who explains how twisted the teachings she’d received about Hell were. Lily becomes her guardian, and over time, Sharkie regains her natural curiosity and sense of safety and family. She is eventually adopted by Lily, Bel, and Lucifer, and by the end of the narrative, she follows in Lily’s footsteps and works at the Hellp Desk.

Lucifer is a secondary character. As the ruler of Hell, Lucifer oversees the dispensation of Judgment to all mortal souls and has a morally inclined sense of justice. He has strong friendships and often takes part in trivia night, plays pranks on his friends, and meddles with their love lives. He is especially soft toward mistreated children, which is why he takes an avid interest in Sharkie when Lily calls on him for assistance. As Lily realizes throughout the story, Lucifer defies the mortal depiction of the devil, as he is in fact a being that exudes kindness and understanding and not the conniving evildoer that is taught in Lily’s Evangelical church. As Sharkie remarks, Lucifer is often alone as head of the Afterlife. By the end of the narrative, however, Lucifer has accepted the position of “Papa” to Sharkie and ultimately adopts her.
