On the one hand, I'm blown away at how much I enjoyed this. On the other, there are some details I thought were odd.
First off, I love the characters—I've said it before, but I can excuse quite a lot personality-wise if the characters I'm reading about have fun and creative powers/circumstances. But even after that, these characters aren't shallow at all. We get a few slower moments where it's just one person talking to another about things that hardly matter—like coffee.
Dictators/tyrants from history become heroes, and the kindest souls you'd ever read about become major antagonists. I mean,
Nightingale, Cyrus the Great, and Charlie fucking Chaplin are all
extremely powerful antagonists for godssake. It's awesome and exactly what I like in stories like this.
My only critique however, is the timeline. It clearly works on an arc based structure, which is fine for a manga since it's not like a book or movie wherein there's a clear and obvious conclusion. But the jumps from arc to arc are very... heavy handed? I guess. The reason I noticed, is because the stakes get higher and higher each time, which requires a certain reaction from our protagonists, which doesn't always align with their goals, motivations or thoughts, in the previous arc.
For example, at the start of the story the conflict is
in actually becoming a Returner. The worst thing you need to worry about is Albert Fish or John Wayne Gacy stringing you up. The goal for our protagonist was to
steal as many talents as he could. Awesome, cool, we know where we stand, great!
You want to know what the conflict is at the end?
The actual end of the world. You want to know what the goal of our protagonist is then?
[SURVIVE]. Seeing these two arcs side by side, tell me that isn't insane. And so I guess my problem is that individually, these stories are fun and they work pretty well outside of any relevant context. But then you put them together, and you can start to see where they begin to clash.
Going from hunting reincarnated serial killers, to facing off against the "King of Villains" (but actually he wasn't a bad guy, the bad guys are the people the protagonist has been working with), to going up against the most well known rulers in history, to then preventing the end of the world... It's a lot. That being said, the stakes had to be high if you're bringing in history's worst/best. But why they didn't start the manga that way confuses me a little. If we knew the stakes were going to be this high from the beginning, then the jump wouldn't have been so jarring.
Especially since the powers went from teleportation, future prediction, and healing to
antimatter bomb creation, orbital laser and infinite darkness.
But anyway, regardless of all that, I really did enjoy this one and I'm really excited to see how it ends.
