Story: 8

Very entertaining and engaging. The manga manages to give a twist to the concept of time loops, and keeps you abreast of the decisions that the protagonist will make taking into account his goal and curse.

Art: 7

Regarding art, it adapts very well to different situations, emphasizing the macabre of some scenes, not recommended for those with a sensitive stomach.

Characters: 7

As for its characters, they all fulfill their role quite well. Something that I really liked was that unlike other works of this style, the protagonist is not so much a genius or a defenseless child, but someone who makes decisions ...

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 ...

It must be one of the mangas with more conveniences that have ever crossed my face. However, ironically, for the protagonist there are rather few; the rival detective is the one who gets almost all of them this time. Very cool also the conveniences of characters that, coincidentally, with how big Japan is, are always there to be found when the plot requires them to do so. There are tons of plot holes, and the author simply overlooks too many details that are essential for a psychological thriller like this work.

On the other hand, the atmosphere in general is very well done: it transmits an ...

Shout out to stories about “People put into the absolute worst situation possible”. Gotta be one of my favorite genders.

This is a story engineered to question your morality as a human being. Right from the setup, how the hell are you supposed to react when put in a time loop where killing is the only way to tomorrow? Maybe you can react to it properly, formulate a reason, a way, but oh no, of course we can't give the protagonist, Kusakabe, a nice day. Put his sister on a timer, and watch the whole world burn. No time to think, no time to give ...

Preliminary (20/55 chp)
I've been following this manga for several months and I guess only 20 chapters have been translated into English (although all 55 are translated into Russian) so far. I'm basing my review on those first few chapters.

I am someone who likes edgy manga. When I say "edgy", I mean a manga that unites two things: originality and transgression. A manga that merely violates taboos is not "edgy", it's just offensive. In this sense, my application of the word "edgy" to a manga is a compliment of the highest order.

Gyakusatsu happiendo is a very, very edgy manga. It's plot is a combination of two very popular ...

What if tomorrow never comes, unless you kill someone?

Are you fans of Death Note? or are you familiar with the survival manga Signal 100? And Gyakusatsu Happy End is strongly recommended for you! Bring you the writer of unpopular survival manga Signal 100, Gyakusatsu Happy End has a lot of bloody stuff, different from the Signal 100, this series contained more logically killin stuff rather than a graphic gore stuff.

Story 7/10
Kusakabe Makoto, a highschooler with his poor life (abandoned mother and living with his not-caring father), only has his little sister lying down in critical condition in hospital. But somehow hope is coming to him, his sister could ...

It was a thrill ride, I won't drag on this preface too much and just get to the nitty gritty of the review for those interested in this banger manga.

Story: 10

The time travel trope tends to either be done poorly, or be done well, there's usually never any in-between. It was done in an interesting way in this, and definitely done well. It's equatable to how Steins;Gate did it, granted they're two different styles, it was handeled in a way that they're close enough to compare (the way time traveling is handled, not the genres). I can't say it's the most unique, but it's a ...

Suspension of Disbelief to the max level

Quick emotional thoughts: I feel like people are giving this manga too much credit. The premise is really interesting and it's what got me hooked onto it, but about halfway it just got way too silly. Things started to just happen for no reason with no explanation, and I wish I could give examples on here but it would be spoilers for those that want to read it. It's a real shame too, since last night I went to bed excited to read more, only for this time I'm going to bed annoyed at how it became.

Now with ...
