First I'd like to say I'm providing a review fairly early. I've only read the first volume, and honestly this is more of my first impressions, but I'm mostly making this since there is NOT a single review as of December 29, 2014. That is ridiculous.

Story: 8/10
Notes: From volume 1 you quickly understand that the story is heading in a very interesting direction. Nearly every chapter gives a sort of episodic feel with a new character or a couple or group etc, that is attempting to pass through the gate. The bailiff is a sadistic tyrant, or as I'd put it, a psychopath. I could go on but so far the story can be tldr's as:
Some person or people are trying to pass through St. Gotthard Pass and "Wolfsmund" figures them out, and then decides to kill them in some harsh way. Either beheading or the person(s) dies in an even more tragic way.

Art: 9/10
One of the strongest points of this manga. Very nice art, reminds me of Vinland Saga and of Attack on Titan but with the lines that Tokyo Ghoul has (at times). Excellent art.

Characters: 8/10
As much I as love the characters, it's tough giving this a high score (honestly should be a 7 not 8) when the characters die by the end of the chapter. However our bailiff is one of the most interesting characters I've read in a manga recently, and I keep wondering if he's really sadistical just to uphold honor and law as he claims, or if there is more to it....

Personal Enjoyment: 10/10
Love the series. It's one of the most enjoyable reads I've found recently. Combine that with tragic deaths, and Vertical is printing the manga (great looking and awesome covers) definitely makes this a great series to purchase.

Overall: 9/10
If you're a Vinland Saga fan, definitely read this. Otherwise I'd recommend reading the first chapter to decide if it's for you.
I'll add some edits to this review if Ookami no Kuchi: Wolfsmund goes in a different direction or when I read more of the manga.

Cannot mention enough that this might be more of a first impression type of review than a full length "seen it all" type of review.

Anyone who's a fan of this manga should provide there own review to help increase the popularity of this great manga series.

This concludes the First Impressions esque review.
