Terra Formars is awesome

I recently started but so far I really like this manga. But something about the ending for chapter 3 is confusing me lol, atm im on chapter 4. If you enjoy reading seinen this might be the manga for you, its about a group of inexperienced astronauts being sent to mars to fight off cockroaches that were sent to mars in order for the planet to habitable for earthlings. However although they maybe in inexperienced they have undergone special surgery to complete this mission. Giving each one of them special abilities to defend and attack. Also these cockroaches aren't your average cockroaches, they have evolved to be more human like. Let me know if you like it or dislike.
