Witches suddenly declare war against humans, causing two-thirds of the world to fall apart. They summon monsters called "Supporters" and devastate human residences... but why?

Survivors gather people with the power to combat the witches and called them Witch Hunters! Tasha Godspell is one of the strongest nicknamed "The Marksman" along with his "Jack-O-Lantern" looking Supporter. He fights the witches but cannot really bring himself to hate them...

Kenn's Comment: People have said that elements of Full Metal Alchemist, Fate/Stay Night and Kurohime in it. Well, all three of those series are really good, so you know it's a good series. In terms of fanservice, it's definitely less than manhwa by Im Dal Young (even though he's usually the author). The action scenes are nice, and the shorts (joke panels) added at the end of every chapter are all really quite funny. The character designs are great too. Story wise, I have to say I'd have to go and re-read it since I've put it off for a while, but from what I remember it was pretty good. Just as a note, as with most Manhwa (unless it's also serialized in Japan), this would be read left to right, like you'd read a book in English.
