The Fandom Post is reporting that Crunchyroll has added the first season of the Vinland Saga anime to its service. The series is available with Japanese with English subtitles, as well as with French and German dubbed versions.
The story of Vinland Saga is described as:
Raised on tales of the legendary land of Vinland, where warmth and plenty abound, young Thorfinn dreams of leaving behind the cold climate of Iceland and venturing into the great unknown. But when Viking sails appear on the horizon, the young boy is conscripted into a life of violence and brutality at the hands of merciless Viking Askalaad. With nothing left to him save revenge, Thorfinn swears vengeance against the man who slew his family, plunging headlong into a sprawling, blood-soaked, coming-of-age epic that marches to the drums of war.
