This will majority be a spoiler free review though obvious spoilers will be marked as such. I just spent the past four hours binge reading Gyakusatsu Happy End. Lets talk about it. STORY 8/10 The general premise of Gyakusatsu Happy End is highschool boy gets stuck in a time loop where he has to murder people so that his sister can survive to her surgery. Simple enough right? However where this manga shines is where it takes the story. The story itself can be incredibly predictable at times and there were multiple times where I had correctly guessed where they were going with it. However that didnt deter me from seeing it through to the end. That unfortunately is where the majority of my ire for this comes from. Spoiler free TLDR: Cliffhanger ending left me raging but some might like. VISUALS 8/10 This is certainly one of the strongest aspects of the manga. Hirokazu Mukourahttps://anilist.co/staff/110979/HirokazuMukoura is an incredibly strong artist and you can 100 tell they had an absolute blast drawing the panels for this manga. CHARACTERS 7/10 The characters were fairly enjoyable. Here are some of my specific thoughts towards some of them: Makoto Kusakabe very frequently teeters the edge of villain and antihero but he still clings to that hope of morality sometimes at the worst of times. This is both his strength and his weakness as it shows its face at some of the worst possible times for him. Detective Tsukumo was a fairly comic character as we are introduced to him via him consuming sugary foods in bizarre ways like drinking liquid red bean jelly or dipping chocolate into mustard. However he ended up as one of my favorite characters purely due to his unpredictability and obsessive actions that left me gripping my seat. Detective Midzuno starts off as the comic relief to the already comic Tsukumo but really evolved into a character that I highly enjoyed by the end of the manga. Katagiri in opposition went from a character I was very sympathetic towards to one I absolutely despised. Thats what she gets for being a yandere I suppose. OVERALL Gyakusatsu Happy End is a very predictable cluster fuck of gore rape and weird fantasies. However while that normally would put me off from any sort of story every rapist that we see on the page gets what they deserve and I respect that in a manga. While I wouldnt recommend if you have a squeamish stomach or are sensitive towards stories with fairly common mention of rape and sexual assault I would very much recommend if you like stories about time manipulation murder and dealing with the consequences of such time manipulation. Gyakusatsu Happy End has many highs and lows but I do think this manga is really slept on. However I hope you get to read it in a different way than me as I read it as a Japanese Russian English translation so it was.... a bit awkward at times if you would believe. :P
