The story has a very slow plot that becomes boring after a couple of chapters, the main character is detestable "Kouta", despite showing his past and argue it well (until the fucking last chapter) seems a retarded boy who You tell them not to do something and it ends up doing and what is bad. The other characters are just as slow and with a well-argued past, but insist the plot makes it all very boring. At the end doubts are recurrent as they leave an open and incomplete parts of the story end.
The drawing is bad, stiff and with very little explained sync with the action, the only thing that could be good would be the gore scenes, and believe me that are yet something bad.
I never liked the opening so always skip, like the ending.
In general, in my opinion is an anime that I did not like at all, despite having a large fandom, I think it's very bad, to spite of the argument is interesting, it is not known address well and ended up leaving history completely unfinished.
