I won't lie the story is all over the place, it had charm but the author simply didn't keep things in a well-done line, he could have branched the story this isn't impossible, it is just difficult, i can see something more if the story was handled better. It really felt like he was just doing things as time passed without a real idea of what was going to happen and going by other works of him i suspect this is a problem to him, he doesn't seem to know how to plan his stories.
Which is a shame i really like his art style, the details and designs are really cool and pleasing at least for me, i would like that if he did another work with fantasy genre like this one but it would be better to find someone to write the story for him.
I found Kanata being pregnant really funny, when people spoiled it here i thought it would be strange, but in the end, it really made me laugh ( maybe because my mind is wandering to strange places concerning it ).
Little sad it couldn't develop more it wouldn't be a manga for the ages but i think it had something to at least be memorable. I will read it again just to feel the bittersweetness of something that wasn't.
