List of Characters
- Thorfinn (トルフィン Torufin?): Loosely based on the historical personage of early Vinland explorer Thorfinn Karlsefni, Thorfinn is a teenage warrior in Askeladd's company, though he hates his commander for slaying his father Thors and has sworn to kill him in a duel. To earn the right to engage in these duels, he must complete difficult feats for Askeladd, such as sabotage or the killing of enemy generals. Thorfinn is a Jomsviking noble through his mother Helga and inherited superb physical talents from his father. He does not fight for the love of battle, but is still prone to losing his composure when in combat. This hotheadedness often costs him battles against more experienced opponents. After Askeladd is killed, Thorfinn enters a rage and tries to kill Canute, which results in him being made a slave for a farmer.
- Askeladd (アシェラッド Asheraddo?): Askeladd is the commander of a small but powerful Viking band, which owed its success to Askeladd's exceptional intelligence. He is half-Danish and half-Welsh, being the son of a Welsh princess captured by a Viking raider. He believes in the legend of Avalon, which inspired him to support Prince Canute's bid for kingship of the Danes and ultimately sacrifices himself assassinating King Sweyn in order to install Canute as the Danish King and to ensure the safety of Wales from Denmark. Ten years before the main Vinland Saga storyline, Askeladd accepted a contract to assassinate Thors, father of Thorfinn. During the Viking invasion and war in England, he manipulated Thorfinn's desire for revenge against him as a way of keeping the gifted young fighter in his service. Askeladd is one of the most skilled fighters in the series, and is particularly adept at predicting his opponents' moves in combat. Askeladd shares the name of Askeladden, a Norwegian folk character known for his cleverness.
- Bjorn (ビョルン Byorun?): Bjorn is Askeladd's second in command, a burly man who fights for the love of combat. He is a berserker, able to enter powerful rages through the consumption of certain mushrooms. Bjorn was heavily wounded in Gainsborough from injuries sustained protecting Prince Canute. The injuries were so serious that he did not have long to live, and later, he challenged Askeladd in a duel. During the duel, Bjorn revealed that he always wanted to be Askeladd's friend, and Askeladd replied that he was his only friend, before finishing him off. Bjørn is Norwegian and Swedish for "bear", a given name commonly associated with Vikings.
- Thors (トールズ Tōruzu?): Thors is the father of Thorfinn, a Jomsviking general whose phenomenal combat prowess earns him the epithet "The Troll of Jom". Thors grows weary of battle after the birth of his children, fakes his own death, and retires to become apacifist farmer. The Jomsvikings later discover that Thors is alive and force him to return to the battlefield. Before he can arrive at the theater of war he is betrayed by a former comrade, Floki, who hires Askeladd to assassinate him. Thors is largely considered the greatest fighter to appear in the series, having defeated the likes of Askeladd and Thorkell in single combat with his bare hands. Such was his strength that Floki was unwilling to engage him directly, even with an entire squadron of Jomsviking warriors. Thors' name is similar to and could be based on that of the Norse god Thor, they were both powerful warriors and had deceptive enemies with similar names (Floki for Thors, and Loki for Thor.)
- Thorkell (トルケル Torukeru?): Thorkell is a Jomsviking general and brother of the Jomsviking Chief. A giant man who loves combat he defects from the Danish army to become a mercenary for the English, believing that fighting his fellow Vikings will give him a better challenge. This same love of war leads him to support Prince Canute's bid for kingship of the Danes. He remains under Canute once he becomes king. Before Thors' defection he works with and highly respects the man, and bears a fondness for his son Thorfinn in the main plot. He duels twice with Thorfinn and dominates each time, though he loses two fingers in the first duel and an eye in the second. In battle, Thorkell typically wields a pair of axes as his primary weapons, but his greatest asset is probably his vast physical strength. During a skirmish with Askeladd's band, he hurled a spear with such force that it skewered three men at once, despite having been thrown from several hundred feet away. Thorkell's character is based on Thorkell the Tall, a historical Jomsviking lord who is a mentor to Canute in the Flateyjarbók.
- Canute (クヌート Kunūto?): Canute is a 17-year-old prince of the Danes. He is initially portrayed as timid and womanly, with a bishōnen appearance and an inability to function without his retainer Ragnar. These traits, along with his strong Christianity, earn him the mockery of the Vikings with whom he works. After Ragnar's death, however, he has a sharp reversal of personality, becomes strong and kingly, and develops an ambition to create utopia on Earth before God's return. Towards this end, he plots to overthrow his father Sweyn Forkbeard and take the crown of the Danes. Canute is based on the historical King Canute the Great, the most prominent Danish ruler of England.
