A vision of heaven with a journey to hell. It sums up well a work with extreme potential, wonderful ideas, but all wasted by a wrong pace and low production. This is the fourth season, the anime closed the main plot and adding the special episode gives a total of 49 episodes. I haven't read the novel, but I know there are 200 chapters. Therefore, I believe that they must have adapted everything and that there should not be a fifth season. Even because I was informed by third parties that the anime adapted everything that was written in the novel. Maybe the plot was alreadygigantic for that amount of chapters in the novel and the anime only replicated the problem with an insufficient amount of episodes. I also don't know if something was cut from the novel, but regardless, the main problem with this anime is that everything seems absurdly compressed. Therefore, it becomes difficult to get involved with some characters, to understand the plot, and to accept the twists and turns as if they were natural. I know this was the case in other seasons, but in this last one the impression is as if they had put much more content than the previous three together in one.

Everything is extremely fast and gets boring to follow. In one episode, a charismatic character is presented, and in the next he dies. In one episode an arc begins, for the other to end. Because of this, the purpose of many things seems meaningless and the resolutions are poorly explained. At least in the other seasons, even with the few resources, the fight scenes didn't seem fast-paced. Now, if someone blinks their eyes, they lose everything. The worst thing is the epic conflict season, the peak of the work, and the anime simply skips the decisive battle without showing anything. I understand that the work has been discredited, that the production is low budget, but this is the end. Even if it wasn't shown in the manga, since the anime hadn't delivered anything special before, it needed to display something grand and rewarding in the epilogue.

One might believe that with all the problems that exist in this anime I should hate it, but I definitely can't, because a huge amount of excellent ideas are presented. The anime even starts to develop some of them well, the problem is that it just starts and already jumps to another wonderful idea that will again have the same fate. So I have a mixed feeling. On the one hand, I am extremely happy that they adapted this work into an anime and would love to recommend it. On the other hand, my eyes literally water and my heart sinks to see that something with such potential has not been adapted accordingly. Also, as much as it's not a great adaptation, it's just average, and when I think about the rubbish that comes out every season, my mood improves.
