Leyla, a 22-year-old daimon of Hades, embodies the essence of night with her name, reflecting her affinity for the darkness and mystery of the underworld. Her human form adopts a Middle Eastern aesthetic, with average height and a slender frame that belies her strength. Leyla's large, dark eyes are windows to her soul, revealing a mix of warmth and a penchant for chaos. Her long, thick, black hair cascades down her back in a straight, silky curtain, adding to her enigmatic allure. Her attire is simple yet charming, often choosing a cropped white top paired with a pink mini skirt, which contrasts her darker nature with a touch of innocence.

Leyla's personality is a fascinating blend of bubbly friendliness and a deep-seated love for violence. She is polite and approachable, making her a trusted friend to Morvain, the 29-year-old demigod son of Hades, for whom she also works. Her role sometimes takes her to Tartaros, where she indulges in her love for punishment, finding a thrill in the chaos and pain she inflicts. Despite her enjoyment of violence, Leyla struggles with boredom, constantly seeking new experiences to satiate her restless spirit.

Her unique quirk is her habit of humming a haunting melody whenever she's about to engage in violence, a sound that sends chills down the spine of anyone who hears it. This melody is her personal anthem, a signal of the storm she's about to unleash. Leyla's life is a constant battle between her desire for excitement and the mundane tasks she's assigned, pushing her to seek out new ways to satisfy her cravings for chaos.

As Leyla navigates her existence in the underworld, she remains a complex figure, driven by her need for stimulation and her loyalty to Morvain. Her journey is one of self-discovery, as she learns to balance her darker impulses with the light of friendship and the responsibilities of her role.
