A decent concept with a poor execution. I gotta commend the creators for doing something unique and original in an industry flooded with a lack of creativity, but it really just doesn't work. There isn't a terribly lot to say about this anime; everyone unanimously agrees that this show was just the definition of "meh", and one of the weakest releases of the season. I stuck with it for the whole 12 episodes just to see if there's any hidden gems in there, but there really isn't.
In the end, I would not recommend watching this anime, but the synopsis is worth a read as a concept. Maybe someone can do it better in the future, or maybe it was just meant to remain as a manga.
