From Viz:After humanity’s first manned mission to the Red Planet was lost, a second expedition arrives. The explorers prepare to exterminate the cockroaches that were used to transform the Martian environment but are shocked to discover that the insects have mutated into giant, aggressive humanoids with one overriding goal - exterminate the humans! However, this crew of explorers has each undergone the “Bugs Procedure,” terrifying experimental surgery designed to make them more than human. 5g4m3u

In the 4th chapter something happens that might show that terrible misconceptions about evolution aren't the author's true state of knowledge and
the roaches are creations made the same way as the bugs #2 guys. At the end of the chapter though it goes back to the way it was, or does it? ! Something might have actually helped in the roaches' evolution into what they are now. Overall: great art, great action, plot starting to unfold. Looks like something between Zetman and Gantz, and near Gantz in my book. ! I like the combination of muai thai and locust legs :).

No matter what the story is about, but anything base on cockroaches is deeply disturbing _........... This manga gonna give me nightmares. I wouldn't be surprise later on we see these alien creature have wings and fly which we all know some do.
So far...i've only read until chapter 2 but i agree with hadou-ken you dont judge series base on the first chapter give it at least 10 chap before you talk sh*t.Especially with a series like this.
It bothers me when someone talks about a series based on the first chapter. This series is amazing. The art is awesome and the plot is complex; it leaves you wanting more after every chapter.
The synopsis says it all but then comes the... surprise of the design of the cockroaches. The fact that the crew is sent there to kill them and take the land is the icing on the cake. I like to believe this whole thing was unintentional but eh.
Rating: 1/10 for being funny in a horrible horrible way.
