Wolfsmund (狼の口 〜ヴォルフスムント〜, Ōkami no Kuchi: Vorufusumunto) is a Japanese historical fantasy seinen manga series written and illustrated by Mitsuhisa Kuji [ja].
Each of the cantons ruled and managed their own section of the Gotthard Pass, and gathered much revenue from charging merchants and travelers en route.
Starting mid-13th century, the rich and powerful feudal Habsburgs began fighting central Swiss cantons to gain sole control over the profitable Gotthard Pass and the lands around it.
It is explained that he has already captured all three cantons, and now works to destroy any resistance, with the resistors and protesters facing harsh consequences, most often death or torture.
Ironically, Wolfram attempts to subdue the rebellion using his cruel methods ends up making more people join the Eternal Alliance to the point that they have enough men to lay siege on Wolfsmund.
On Anime News Network, Rebecca Silverman gave volume 1 an overall grade of B, calling it "brutal", saying that it "pulls few punches and hits you in the gut" and recommending it to "fans of historical fiction that pays attention to the history or those looking for some well done seinen".
