well to begin with the concept itself is really amazing and the animation is top notch,the starting might be kinda slow but further down the road it makes you stay on the edge.Overall a fantastic anime easily in my top ten.I would give this show 11 stars if possible hats off to the writers.It might come as a new concept believe me its worth every millisecond of your time but it has only 25 episodes which is kinda sad u might finish it in a few days, i think you cannot continue these thriller anime for long so nothing to blame.Coming to the plot , one word "amazing" it mainly revolves around a student who thinks that he is a mad scientist and it moves on to all his research and experiments and how he meets new people during the course of time.Nonetheless i wish you enjoy this anime as much as i did.
