Synopsis

In high school, Maki Eiji was a delinquent, often skipping class and getting into fights. One girl, Chino Kotoha, was kind to him, until she was targeted by delinquents due to their apparent relationship. Suffering their attack seemed to have permanently changed her for the worse.

Years later, when Eiji sees her again, he is overcome with guilt and regret. To his surprise, a mysterious scantily-clad woman suddenly appears, claiming she can send him back in time to make everything right! He takes her up on the offer, but things are not as simple as they may have seemed back then. It turns out that Kotoha had her own painful secrets in those days, and Eiji may not be the only one traveling in time to change the past!

I find this manga from the wronged works that have not gained enough fame personally. I find that the manga has an attractive story that attracts attention, characters with a complementary relationship, a sad and beautiful drama at the same time, a very beautiful and acceptable ending. Perhaps what I like the most is the story in particular, so you think that the return To the past in order to correct mistakes is good, but with the aggravation of events, you will know that regret is inevitably present with a lack of confidence in the people closest to you! It is also full of ...

Preliminary (14/21 eps)

Hensoku-kei Quadrangle.
Okay I'll admit. I stumbled upon this manga while looking at manga similar to "Erased". The synopsis of the story was interesting as I thought it would be about the main MC trying to help the main heroine not relive her past mistakes and while doing so would come across "bad guys" who also traveled back in the time and somehow problems would arise, BUT the story is totally what I did not expect. First and foremost, the main issue with this manga is the development. Everything is kind of blatantly mentioned and nothing is really kept a secret for long. Within the chapter, ... some character may have a deep secret or hidden past but about maybe 15 pages later, the character confesses what his secret is and it ruins the development of the characters. No one is really built up except the main MC and everything seems like it was forced to end quickly on purpose.
Now I haven't read the entire thing because the project has been dropped but despite all its flaws, I still wish I could read the ending because the story is interesting. Like the other review saying that this manga turns into a "WTF is happening", I did get the same feeling but as an optimist, I really want to know what's going to happen to each of the characters. A lot of the premise regarding the time traveling is hidden so there's some positive to the plot.

Story 7/10:
As said before, the plot is rushed, there's really no development, every secret is exposed within a chapter, and everyone has some stupid motives for going back in time except the main character. Again, I haven't finished the manga so I have somewhat hope that the ending will be spectacular and everything will fit together but I doubt it.

Art 10/10:
Dude! This guy's art is brilliant holy crap. The color pages are BEAUTIFUL and just every character is well drawn. The background is gorgeous and everything that this guy has drawn from start to finish has been consistent. Best part of the manga BY FAR.

Character 8/10:
Eh the characters are your typical:
You have the main MC who somehow knows martial arts or something and beats up everyone but sees what his action ultimately consequent to so he goes back in time and tries to prevent it happening in order to save the girl he loves. Yeah, it's that stereotypical character again, only difference I would say is that the main MC doesn't really care if the main heroine loves him or not, he just wants to save her, so I guess that's somewhat different.
You have the main heroine who is super nice to everyone and has a dark past and hates herself for that. She smiles at everything and eventually starts having feelings for the main MC because he saved her and somewhat confessed his love to her. EH I still thought she was pretty adorable so I gues she wasn't too bad.
You have the other heroine who is jealous of the main heroine and wants to become like her and is overly protective when it comes to her. Not much to say about her besides the fact that I think she's best girl, when it comes to feelings and interactions I felt that she was more genuine, but still a stereotypical character.
You have the cold, tall, handsome, can't speak character who doesn't want to associate with anyone but eventually gets a soft heart and begins to change his character.
Yeah these characters aren't really unique but still I liked them because they weren't cry babies or hindered the plot so I'll give them a 8/10.
Overall, this manga is okay. I enjoyed it. It had a lot of potential in the beginning but I felt like everything was a bit rushed so there's a bit of a downer to that. But in the end, I'm sad that this manga has not been fully translated, I hope in the future that this project gets finished and that we all may read this manga together.
I would recommend this manga if you like cute romantic moments with a cool main MC. Interesting plot that falls short(SO FAR) but in the end I give this manga a 8/10 .

Good manga with a interesting story about people trying to rewrite their past and mend things but gone to WTF IS HAPPENING?.

We have 4 character that are the main:
Our protagonist, a former high school thug and now a former thug with regrets. He wants to go back to the past because a girl got raped because some thugs tried to revenge upon him raping the girl.
The girl, a pretty girl. She was very friendly with our little thug and always tried to make him behave good. By the way, our main character falled in love with her. In reality, she wasn't really raped. She passed ...
