I'm not sure how this anime has such a high score, do other people just have a much higher tolerance for unlikable characters and a generic plot? This anime is so absolutely cookie cutter it's a joke that it has a rating of around 4 stars.
The opening scene of the first episode is intensely graphic, we see devilish creatures eating what we assume to be people. The bodies of hundreds casually discarded on the ground, most of them wearing horrific expressions. The scene following that? Two main characters doing slapstick comedy in the forest while trading magic with some random soldiers.
In another part of that first episode we see the characters being followed, accidentally tripping some deadly traps but more comedic than anything else. The scene immediately following? A boy in a city we’ve never seen before trying to attack some city official he believes has kidnapped his sister (I think, the show is really confusing) and attempting to hold him at knife point.
The only thing good that I can say about this anime is that it looks and sounds okay. Nothing special, just that its on par with most other animes out there.
It feels like this anime doesn’t know what it wants to do, it tries to be dark with all these graphic images and gritty undertones but attempts to liven it up with an unnecessary amount of slapstick comedy. The end result is an incoherent pile of garbage. If you have literally nothing else to watch, still I wouldn't recomend this.
