I was really enjoying this series, having the first season of its anime as one of my favorites, but the end of the story and, in general, the development of the last arcs has been poor and full of meaningless, disconnected events that did everything but get him to empathize with the protagonists.

The end of this series seems like a bad joke to me. The author had thousands of possible endings to choose from to end the story and has decided to end it in the most passive and unsuccessful way possible.

After the last chapters, I have passed the final grade from an 8 to 6. The tease for which we have been submitted by the author does not deserve more than a 6, being very generous.

Too bad, because it had the potential to become one of the great manga / anime mystery / thriller series, but it hasn't. Too bad.
