This manga sort of functions like a compilation of short stories, each short story having a different setting and set of characters than the last. The only characters that are consistent between chapters are the Vocaloids (and even some of them are missing in certain chapters.)
There is a wide variation of story lines between each chapter. The plots can at times be very hard to follow, but other ones are relatively straightforward. None of them are very well written, they're amusing at best and confounding at the worst.
The art is done by the original character designer of Miku and I have to say, he(?)
does not disappoint.
However, the series is nothing beyond some decent art and some silly stories. If you're a Miku fan or you want something that's a little bit out of the ordinary, then it might be worth your time. If not, much better manga out there than this.
