This manga is pretty great. I really want to know what's gonna happen next cause the world and some concepts (like the relics) are truly great. Post-apo story is a big yes : deadly ruins to explore with terrifying creatures, that's NICE ! Some shots truly convey intense emotions and show the deserted (yet full of treasures) aspect of the world *.* HOWEVER why is Alpha like that ? I mean she's supposed to be a super A.I and we've got an exhibitionist... Yeah viva that kind of "fanservice" -_- But that's the only (big) drawback for me cause art is Amazing and story isintriguing (I only read 1 vol for now).
I just hope that the "Why are you naked ?!" jokes won't last all manga long... (Or tell me : does it get worse ?)
I do recommend it anyways :')
