This manga is simply... amazing. 10/10 The story is really good, it has depth and complexity. For you that read and liked Gantz , you are going to love Terra Formars. Just wish the info about bugs would be getting a little less attention in the story telling, but well its important to understand the powers characters have so i guess it's fine. 10/10 The artwork in this manga is outstanding, it might be the best drawn manga i have read up to now.9/10
Character development is also pretty good, but its to bad characters that you get to like keeps dying...

10/10
Overall, definitely worth reading. Give it a shot, i promise you that you wont regret it.
