The narrative centers on three demonic infants—Mimi, Kiki, and Lulu—who are born in Hell to a human mother and a demon father. Each baby possesses unique, grotesque abilities: Mimi can summon fire, Kiki has superhuman strength, and Lulu can manipulate her body into various shapes. The trio is raised by their mother, who struggles to care for them in the chaotic, nightmarish landscape of Hell.

The story unfolds as the Hell Babies grow and explore their environment, encountering bizarre and macabre characters, including other demons, tortured souls, and monstrous creatures. Their adventures often involve violent and absurd situations, such as battling rival demons, navigating twisted family dynamics, and confronting the moral ambiguities of their existence. The Hell Babies' actions frequently blur the line between innocence and malevolence, as they exhibit both childlike curiosity and destructive tendencies.

As the narrative progresses, the Hell Babies face challenges that test their bond and their understanding of their place in Hell. Their mother’s love and guidance play a crucial role in shaping their identities, even as they grapple with their demonic nature. The story delves into themes of family, identity, and survival in a hostile world, all set against the backdrop of Hell’s grotesque and fantastical imagery. The manga’s tone oscillates between dark humor and unsettling horror, creating a unique and immersive experience.
