Dale Reki, an 18-year-old renowned adventurer of the city of Kreuz, is highly skilled, kind-hearted, and commands respect from his peers. During one of his hunts for magical creatures, he stumbles upon a pitiful devil girl known as Latina. Donning rags and bearing the sign of a criminal, a broken horn, Latina is vulnerable and alone. Overcome by concern for her safety, Dale takes her under his wing, bringing her home and ultimately adopting her. Latina's innocence, sweetness, and compassion quickly endear her to Dale, leading him to embrace parenthood in all its trials and tribulations. Though his dual role as an adventurer and father separates him from her often, Dale cherishes the time he spends with Latina, and the love he feels for her continues to grow. While Dale's life assumes a semblance of stability as a parent, questions about Latina's past linger. Why was she alone in the woods, and what connection does she have to the criminal underworld? Meanwhile, Latina experiences her own journey of self-discovery in her new environment, gaining knowledge of the world around her and discovering who she is as a person.
