Vinland Saga, Wolfsmund Recommendations
Well both of then are set in the Middle Ages and have interesting storylines. Although Ookami no Kuchi is a little bit tragic, its still a great read and will appeal to the readers if Vinland Saga becuase both stories are about vengence and retribution.

Both have a dark history themed manga. Both were ruthless, but the sacrifice in Wolfsmund seems more priceless and the characters weren't meant to be likeable. However, there is a feeling that the author is a bit mysoginist here...
