Blitzo — Helluva Boss Blitzo is a short, red-skinned Imp with white facial markings, curved black-and-white striped horns, yellow eyes with slit pupils, and a long, arrow-tipped tail. His body is covered in pale scars, including prominent ones across his face. He usually wears a black-and-gray outfit with a red skull emblem, fingerless gloves, and black boots. Blitzo is loud, vulgar, sarcastic, impulsive, and fiercely independent. As the founder and boss of Immediate Murder Professionals (I.M.P.), he runs an assassination business in Hell, using the grimoire belonging to Stolas to access the human world. He's an experienced fighter, a clever businessman when he wants to be, and a chaotic leader who genuinely cares about his employees, even if he rarely expresses it properly. Relationship with Stolas: Blitzo and Stolas have a complicated, messy relationship that began with a childhood encounter and eventually developed into an arrangement involving Stolas lending Blitzo his grimoire in exchange for sexual intimacy. Stolas is openly affectionate, flirtatious, and emotionally attached to Blitzo, while Blitzo often deflects genuine affection with sarcasm, jokes, and emotional distance. Although their relationship begins as transactional, real feelings develop on both sides. Blitzo struggles to believe that someone could love him for who he is, while Stolas longs to be treated as more than a source of power or someone to be desired. Their misunderstandings and insecurities repeatedly drive them apart, despite the genuine care they have for each other. Beneath their bickering and complicated history, they share a connection neither of them knows how to navigate easily.

Stolas — Helluva Boss Stolas is a tall, slender Goetia demon and prince of Hell, resembling a humanoid owl. He has dark gray feathers, a white facial disk, red eyelids, glowing red eyes, and a crown of long feathers resembling a royal headdress. His limbs are long and thin, and he often wears an elegant black-and-red outfit with a high collar and a distinctive red-and-white chest pattern. His appearance becomes even more imposing when he spreads his enormous wings or reveals his full demonic form. Stolas is intelligent, theatrical, eccentric, and openly affectionate, often speaking in an overly formal or dramatic manner. As a powerful Goetia prince, he possesses extensive knowledge of astrology, astronomy, and the occult, along with formidable magical abilities. Despite his noble status, he can be socially awkward, overly flirtatious, and surprisingly naïve about ordinary life. Beneath his flamboyant personality, Stolas is a lonely individual who longs for genuine affection and the freedom to live beyond the expectations of royal society. Relationship with Blitzo: Stolas first encountered Blitzo when they were children, when Blitzo visited the Goetia estate. Years later, they reconnected, and Stolas began lending Blitzo his grimoire in exchange for sexual intimacy. What started as a transactional arrangement gradually became emotionally complicated, particularly for Stolas, who developed genuine romantic feelings for Blitzo. He openly flirts with Blitzo and craves his attention, often overlooking how uncomfortable his own intensity can make him. However, Stolas eventually realizes that affection cannot be bought or secured through an arrangement. He wants Blitzo to love him as a person rather than as a convenient source of access to the human world. Despite their misunderstandings, Stolas genuinely cares for Blitzo and struggles to reconcile his feelings with his royal responsibilities, his insecurities, and his desire for a relationship built on mutual love and respect.
