Willibald

A Christian monk who serves as the tutor for Prince Canute. Because of his unkempt hair and beard, he appears older than his actual age, but he is, in fact, a young man of 23. When he tidies his appearance, he looks his age. He suffers from severe alcoholism and was renowned for his drinking prowess at banquets, to the extent that he was called the reincarnation of the wine god Egil.

Due to his eccentric appearance and strange behavior, he is often underestimated by those around him. However, he earnestly pursues the question of what "love" truly is within his faith. His pursuit is so sincere that his conclusions become difficult to comprehend, and most of Askeladd's men and the warriors in Thorkell's army fail to understand him. He takes inspiration from the words of a veteran in the Askeladd band—Thors' saying, "A true warrior needs no sword." Subsequently, after the loss of Ragnar, he teaches Prince Canute about the essence of "love," guiding him toward becoming a king.
