This is an enjoyable and worth-while additional read for those who liked Alien Nine, but I still can't help but want to separate the two when I think of them. Alien Nine is a wacky story overall, but it feels as if it has a lot of underlying themes going for it. The original manga built up to a theme which I felt strongly to be coming-of-age and getting over one's selfishness to accept a partner in a relationship. The original manga builds this feeling to a good climax and finale, but this addition doesn't feel like an extension to that building plot from the original. "Emulators" just seems to confuse things even more a bit while still keeping the feeling of those original themes at times, but nothing is built upon really. This is more of some extra interesting scenes along with some extra context to things that go on now or went on before. There isn't really a climax/finale to "Emulators" either as it isn't really one story, but a group of smaller side-stories that generally take place chronologically. Overall I genuinely enjoyed parts of this manga and had fun in some aspect the whole way, but this doesn't feel as neatly-wrapped as the original manga trilogy.
