Belgrieve loses his leg and his adventuring career in one bad encounter, and shortly after finds an abandoned baby in the woods. He raises her as Angeline, teaching her everything he knows before she leaves their mountain home for the capital to become an adventurer herself. Years later she's the Black-Haired Valkyrie, an S-rank adventurer working out of the city of Torrnera, in constant demand for rescue jobs, yet everything she's earned means less to her than one more visit home to her father. This manga adapts the original light novel.
