There is not much to say about this anime, it is so short that it is worth watching. It can be a little more enjoyable if you play Project Sekai or if you are a big vocaloid fan so to speak, because we are talking about 10 short episodes of 2 minutes each, without any plot or development. I should also warn you that if you are a sensitive person or get easily offended, better not watch episode 6, because it contains a scene that caused some controversy (you should look it up so that you can inform yourself of the situation) in conclusion for this shortseries... the perfect anime to watch while you're in bathroom break, or in a long ranked queue.
