Seriously, I've seen plenty of manga adaptations out there that are crap and I honestly can't say for sure that it's not the original novel that's at fault since I haven't read it, but this is just horrible. If the novel author is the one that wrote it like this from the start, he should quit trying since my cat could put together a more interesting story by walking on my keyboard.
I feel like this story could've been somewhat interesting if not for how it appears to jump all over the place. The way it's put together is reminiscent of western cartoons such as the simpsons or family guy, only that those can actually be fun and well thought out. What I mean by that is that the story is disjointed with the characters switching location all the time and nothing is really explained, there's no story progression to speak of.
This is why it feels like the manga adaptation just jumps over every part the manga artist didn't feel was interesting. It feels like a half-assed summary of a story. At one moment, we're at one place, at another we're in another place. All combat scenes are completely skipped just like everything else seems to be. Nothing even remotely seems to make sense. When enters combat, he goes "Dude, I picked up a few tricks at the magic school or whatever that you readers never even got to hear of me checking out, so now I have these abilities" when he uses a new ability. Similar with all characters, not a single of them have any real introduction or story to them. This takes 1D characters to another level.
What happens when you have no story progression, no character backstory, no reasoning behind actions, no leading us readers through the important events so we know what happened, instead just saying "it happened" in 1 sentence? No attachment to the characters is what happens. No care about his actions or the story, readers feeling lost and lacking emotional response to everything. If you don't even get readers to feel like they're part of the journey, you might as well quit being an author, no one wants to read a story like that.
Also, add on to that the rapid sex scenes that comes out of nowher with zero build up and the various rape, molestation and snuff/murder "future sights", I can't help but feel that this author is just a pathetic overgrown baby pretending to be an adult while actually being eternally in his mid teens in maturity, experience or taste. Rather, I would've been ashamed of being placed at the same level as this author when I was at my mid teens, so maybe that's not fair. Someone like this reeks of a person with chuunibyou. They think these things are cool and abuse the ideas. Magic eyes, future sight, being abandoned by a goddess only to be picked up by another for their "moral character"(lol), revenge tripping, sex, saving girls from a supposed future rape or snuff scene... Seriously. Not saying it can't be cool if done correctly but this is just pathetic, everything is thrown out there with little to no thought and literally zero build up, and I really mean literally. There's nothing leading up to anything since there's no story progression or build up, they're just thrown around to different places, times of day, dates and scenes. It's crazy how there's zero story in something that's supposed to be story heavy. Funny how characters also just suddenly pop up and even though they should be important it makes no sense when they come and they're written like bystander A or B, none of their actions make sense.
Whoever made this crap deserves a kick and wake up call.
I'll still read it though because it's a quick read with how little story and text there is, I'm not picky when it comes to wasting some time, at least not for something that can be read so quickly. For novels I'm way pickier since that'll actually truly waste my time and mental energy compared to a short manga. Honestly, if you don't expect anything you can somehow laugh at how stupid it is, so it's not a complete waste of time to read.
One last thing... I really question the author's obsession with rape. It hardly passes even a chapter without a character getting raped and/or tortured, or even killed in the process, be it future vision that won't happen, memory or reality. The protagonist gets visions of those around him, often his teammates, getting raped or molested and some characters(not main stays, of course) get raped for real and and there's a lot of drama about it. Seems that the author has a severe rape fetish or simply doesn't know any other way to make characters experience drama or trauma. Geez. I mean, I've seen "rape happy" writers before that overdo it, but this is just incredible with how it happens pretty much every chapter. Even more ridiculous is how the rape stuff completely lacks substance, it doesn't even matter in any way, so what's the point?
