Ok so this anime does indeed start off pretty generic, we should all see the first 8 or so episodes as the exposition, as the show actually gets pretty dang deep.
STORY:The story is surprisingly complex with some depressing twist, and prepare yourself for Licht's and Nana's backstory. The story also sheds light on a major real world problem: Overpopulation. This leads to hunger,poverty, and eventually war, which is where Licht and Nana comes in. The discoveries we go through as we see these two backstres unfold are jaw dropping enough, but how these stories are told is the real magic. We find out how multiple traditions were created in this world and how the characters react to these events, which brings me to my next topic...
My one and only issue here is the rainbow vomit, it was one scene where tthey just maade the vomit look like a puddle. Other tthat it's fine plenty of chibi kawaii scenes as well.
The dub is actually pretty decent.
Overall if you like mystery and sci fi with echhi shonen style dialog and action scenes this is a musst watch.
Ill leave a mini summary of the first cuple eps. Spoilers so don't scroll.
SPOILER I REPEAT SPOILER
The first couple episodes makes the watchers believe this'll be a nice 12 episode echhi anime, with a bit of action to keep you happy, like Hundred. But at around episode 5 you start questioning things just as Jail is doing. At episode 6 we question why can't they study flying and why dedicate an entire episode to it and 8 is where the real show Plunderer starts.
We see a helicopter in Alcia, this medival world....yea I know fishy. Episode 9 gets even more confusing as the Ace of Pursuit,Mizuki Sonohara appears. After she's 'defeated' we hear Nana say "those people drugged her". This makes things evev more confusing. Well 10 and 11 clears it up (not going to say how) and we're thrown into a modern world.
