So yeah, I was first introduced to this author via Elfen Lied, the anime. Which I adored. Still do. Then I read the manga, and it's ... well, longer and more involved, but for the first time ever, I actually prefer the anime ending to the manga one.
Then I got into Kimi wa Midara [....] which was short and sweet... and totally smut. I quite enjoy that one, for all of it's 2 volumes, nothing compared to all of his other works. Then I got into Nononono(no?) and was extremely bored and turned off by it. Didn't enjoy it at all, didn't finish it either.
Finally got into Gokukoku no Brynhildr, which I loved, but somehow the darkness inherent in it, which is clearly this author's tagline now, got to me more, and so I didn't enjoy it as much as Elfen Lied, even though it was just as dark and tragic.
And now I stumbled across this, and... man... I'm not sure how I feel about it. As noticed by other reviewers, the start is pretty rough, and after a ton of chapters, it really changes tonally. Like if you go back and read the first chapters, they're sooooo different than later ones. Oddly enough, the absolutely comical and ridiculous sex did not turn me away, and that's at least everpresent. What really got to me is the asinine lengths the MC goes to, in multiple circumstances. He's VERY different (in a bad way) from the rest of the author's protagonists, and as a result the work suffers. I mean the world is freaking tragic and disturbing as all hell, even more so than Elfen Lied and Gokukoku no Brynhildr, and that says something. But instead of having a good MC trying to deal with it... I just don't care, because while I can't call him COMPLETE trash, I can't find myself to like him or any other Earth characters. Some of the new world's characters are great, but most aren't important.
But yeah, I just find it very hard to rate this manga. It's dark and it's sexual, but it's TOO dark and the MC doesn't really help mitigate that. It'd be like if you were reading Berserk, but Guts wasn't a protagonist you could root for. Or Goblin Slayer if the titular character died and you had no one to connect with. It's not a 1, but it's definitely not a 10. And it's too individualistic and non-generic to be given a 5. I don't even know if I like it lmao. WTF it's confusing me!
