At first I thought this is an anime gore, because it tells the story of mutilation case in the box. But I was wrong, gore in the anime is not horrible as it sounds.
An anime that is quite complicated. It can't be enjoyed if to pass through dialogue in it. Anime is filled with chatter like this should be followed in patience.
And really, I heaved a deep breath (feeling satisfied) after successfully passing this anime until finished.
An anime that has a great story..
