No reviews, huh.
Well. This is trash. If you have been unlucky enough to see "Rengoku no Karma", this manga is similar - skilled artist for some incomprehensible reason depicting an "idiot plot" (check tvtropes for this one).
The premise is that in some more or less normal classroom, pupils get magical application installed onto their smartphones, it can't be removed, they have to vote, and whoever is voted out is going to experience "social death"... which means some secret of theirs is gonna be posted online, pretty much. Obviously, they all go nuts about it and try to act in most horrific and most nonsensical way possible.
Basically, this is a manga, that uses overly relies on shock, tries too hard to shock the viewer, and is obsessed with depicting humans as horrible horrible horrible creatures that do unthinkable things to each other given opportunity.
In the process of doing that, however, those kind of stories usually destroy any believability of the setting, as they require large number of people that are incapable of any kind of rational thinking. Same thing happens here. None of this is believable, there are occasional "magical" explanations here and there (like that magical app) and so on.
BReakdown:
Story: 2/10. Completely nonsensical and illogical, pretty much as bad as it could get, but I saw two titles that were even worse, that's why it is not 1.
ARt: 6/10:
The art is actually well done - it is one of the more realistically drawn mangas.
Characters: 1/10:
All characters act in permanent idiot mode, none are believable, even though the author tried to employ some archetypes.
Enjoyment: 2/10:
It is quite bad.
Overall: 2/10.
Bottom line: Once again, like in rengoku no karma, we have horrible horribly written story with nice visuals. This title is best avoided, but might be worth checking out if you really hate people, including yourself. The nicely drawn art cannot not save this title.
The theme might resonante with young teens, though given themes touched they are likely not the target audience. For an adult this is likely to look like pure nonsense.
