Nell, whose full name is Nelluru, is a secondary character in the series. She was formerly a slave raised in a violent bandit camp known as the Crows, where she endured physical and emotional abuse from a young age after losing her mother. Her life changed dramatically when she crossed paths with Clevatess and his group. While protecting the baby Luna, she was mortally wounded, but Clevatess revived her using his power, merging her body with troll tissue in the process. This resurrection granted her a new appearance and surprising physical strength.

Physically, Nell is a young woman of average height with a slightly plump build. She has short, wavy two-toned hair, red at the ends and white at the crown, and brown eyes. Her front hair is colored like troll fur, a lasting mark of her rebirth. Before her resurrection, she had a worn, aged look with missing teeth and disheveled hair. After coming back to life, she appears rejuvenated.

Personality-wise, Nell is resilient, humble, and deeply caring. Her traumatic past made her cautious and submissive at first, but as she finds safety and purpose, she grows more confident and assertive. She is gentle and maternal, especially toward Luna, whom she treats as her own child. This devotion is intensified by her own history of losing three infants at birth. Her motivations center on protecting Luna and providing the warmth and stability that the baby needs, as well as finding meaning in a new life free from suffering.

Nell serves as Luna's wet nurse and primary caregiver. In a story populated by a demon king and an undead hero, she represents humanity, tenderness, and normalcy. She is the emotional glue that holds the unlikely group together, balancing the tension between Clevatess and Alicia. Her presence creates moments of genuine warmth and contrast against the darker elements of the narrative.

Key relationships include her bond with Luna, whom she loves as a mother, and her gratitude and loyalty toward Clevatess for freeing her. She also interacts with Alicia, the revived hero, acting as a calming influence. With time, her speech becomes more fluent and self-assured, reflecting her personal growth from a broken slave to a confident caregiver.

Notable abilities include her enhanced physical strength, a result of the troll tissue merged into her body. Although she does not possess magical powers or combat skills, this strength makes her surprisingly robust. Her true strength lies in her empathy, resilience, and the emotional stability she provides to those around her. She is a symbol of hope and redemption in a harsh world.
