It is a very engaging and well-developed science fiction story with an ending that left me satisfied, I liked it, although they could have put some more things that I will not say by spoiler, but they are only details, and it contains a good dose of action with the excellent Obate-sensei drawing.They will not regret reading it, or at least giving it a chance. One of the things I would like to see in the future, and that is very unlikely, is to see an animated film of the work (Since an anime would be to extend the work), but I doubt that willhappen xD.
