Plot 8/10:
The story is set nicely and the plot progress most of the time in a really intriguing way. The mystery and anticipation will keep you on the edge of your seat failing to predict what's next most of the time.

Characters 8/10:
The MC is the best written character, he's the most interesting and is the biggest selling point of the manga.
For the rest of the cast, most of them are well written, some are kinda sloppy which is probably because there is waay to many characters introduced for a 55 chapters manga.
The inspector is another flaw in the characters category. He starts good but ...

Mixed Feelings

High school student Kusakabe Makoto has to work all day to raise money for the treatment of his younger sister, who suffers from a serious illness. The father is unemployed, the mother ran away, leaving the children, bullying at work ... Despite all this, he does not lose hope and continues to live for her sister. But having learned that she did not have long, Makoto falls into despair. Fear of the unknown causes him to take a different look at the value of human life.

Story: A simple story (what to expect from a gore manga). Of course, this one follows the same pattern as ... all manga in this genre, a good protagonist who has something bad happen to him that makes him go crazy and have the police behind him, only that this work has a very interesting resource: time travel. Thanks to these, our protagonist can kill without anyone discovering him, except for the mad detective who is even crazier than the protagonist. He has a good pace, I have to say, but the conclusion is very bad. The reason why he gets his time-traveling powers are absurd, and the end of the main character gave me even satisfaction to see how it ended. 06/10, and that score is for innovating in something

Characters: The protagonist, Makoto, goes from one day to the next from being a little angel to becoming a potential psychopath, with hardly any development, his sister for whom he does all this I am not going to talk about her since she has more appearances in the mind of the protagonist than in the world of this story, appearing very little. The daughter of the prostitute she "saves" is also another little prostitute who is very heavy, has 0 intelligence and is only there to touch the balls, her reappearance after Makoto abandoned her is saving, she is jealous of the protagonist's sister and she reappears as Oolong from Dragon Ball (if you read this manga, you'll see what I mean). Then there's the crazy detective who goes after Naoto, who I found interesting at first but ended up liking him badly, nothing to say about him. The only two characters that for me are saved are the detective's assistant who looks like a cat and gives us fanservice and Makoto's second sister, one of the few well-written. And yet you know what I'm telling you? which are not even so bad. Despite having criticized some of them very harshly, I don't dislike them at all, except for the miniprosti that is insufferable. For me, the characters section is a 07/10

Design/drawing: very graphic, something I like about gore mangas because when you go to read a style manga you look for blood and strong panels. The design of the characters seems very good to me, even the Oolong is very well drawn, the landscapes and backgrounds are also very good and detailed, for me it is a 07/10

Entertainment: I'm hooked, so why am I going to refuse. Although I repeat, I did not like the ending, that revelation of where the powers of time travel come from, more than half of the manga I read in a single day, and there are 55 chapters that are said soon but take time to read having other things to do. In this section another 07/10 will also be taken that could even go up to 08/10

Conclusion: another gore, simple, but with a very distinctive resource that takes advantage of it very well, although adding all these previous notes we get a 6.75 almost 7, I'm going to keep it at 6 because it's simply good, with nothing to highlight

I'm the type that reads most random manga that's out there, as long as the premise is interesting. Gyakusatsu Happy End has an incredible start that starts nose-diving into one of the worst writing imaginable.

Story: 1.5/10
The only thing the story does well is not to let either side hold absolute power and control. It does well on the similarities of Death Note, a cat-and-mouse chase. It has the tension at the start, albeit goofy with the characters that I'll explain later below.

Let's start with the biggest issues thus far - how convenient everything falls into place. The story becomes incredibly dumbed down, not the premise ...
