In "If It's for My Daughter, I'd Even Defeat a Demon Lord," Dale Reki, an eighteen-year-old adventurer regarded as one of Kreuz's top fighters, encounters Latina, a young devil girl wandering the woods. She wears tattered clothes and has a broken horn, which marks her as a criminal in devil society. Worried about her safety, Dale takes her in and eventually adopts her.
Latina turns out to be a charming, innocent, and empathetic child, capturing Dale's heart far more than he anticipated. As he takes on fatherhood, he must handle the challenges of raising a daughter while still fulfilling his duties as an adventurer.
Even after settling into a routine of work and parenting, the mystery of Latina's past remains unresolved. Questions linger about why she was alone in the forest and the reason behind her branded status. Meanwhile, Latina begins to explore the world and her own identity as she adapts to her new life with Dale.
