The tl;dr of this is 3/10, it's bad, don't waste your time, I have no idea how this ever got the score it has, unless this was A Lot of people's first manga.

If you've read just about any other manga you'll be able to tell that this is not good. The character building is third rate at best, the plot is barely extant, the antagonists are laughable and the protagonists are cardboard cutouts of tropes. There are constant hamfisted twists that make M. Night Shyamalan's recent works look like he's back in his prime.

The concept is decent, and the art in some of the fight scenes works. If you're solely here to watch bugs killing people and people killing bugs and don't care about caring about the outcome, then this is for you. Otherwise, don't read this. It doesn't deserve it.
