Volume 1 of the Graphic novel Jormungand to me, is quite an entertaining comic.
The story is structured in arcs, which I think is great. (Like it's episodic.)
The characters are entertaining, especially Koko Hekmatyar, who has quite a quirky personality and if not, a little crazy. Jonah may be cold most of the time but has an interesting outlook, also keeps his cold demeanour as a mask. Not a whole lot of the cast is seen in this volume.
Which is where I bring you to a problem- there is a whole squad of people Koko employed, but we only get to meet about 6 people of the cast throughout the whole volume. (This is fixed in later volumes)
Art wise: The artist's style does not make much use of tones, so the book is done in mostly heavy inks, a bit rough at that (but still enjoyable!) He puts great detail into guns and action scenes, it makes the book very lively!
About the story: The story in the arcs retains a very action based plot, but in the midst of it, there is a feel of comedy at times, which may bother some who are expecting a full on serious serious story.
Also for those who are a bit sensitive, There appears to be bit of love interest (Female x Female) in here, which is great to see in my opinion but may not be for others. (it is more prominent in the second volume, more Valmet x Koko).
In all, I give Jormungand a 4, not a 5 because of the lack of cast introduced and characterised, only displayed for a few panels.
