Honestly, I had high hopes for this anime after watching an advertisement for it. But a few episodes in, the enjoyment I had while waiting for what was going to happen next disappeared.
STORY
The biggest issue for me was that the plot changed, it seems like the producer went off topic.I did not read the original material so I don't know if this is based off what the author wrote or if the producer just made a mistake. Either way, it ruined the show immensly for me. The show was supposed to be about the "Heroes of the SIX Flowers" going to defeat the rising Demon God, yes? But somewhere along the way, the fact that people are dying just seems to slip their minds and the biggest issue becomes that there are SEVEN "Heroes of the SIX Flowers" instead. Seriously, what? Why does it matter if their is an imposter? Especially since it says near the beginning that only demons and the Heros of the SIX Flowers could enter the Land of Howling Wind (I don't remember if this is the correct name or not), so if there is an imposter they'll die anyways.
ART & SOUND
The art is mainly what drew me to watch this anime. The animations were great. Sometimes the background music did not match what was going on, but overall it was okay.
CHARACTERS
I personally like the character variety a lot. Each character has their own stories, some kind of motivation to defeat the Demon King. They don't share the same personalities, each character is unique.
ENJOYMENT
I actually did enjoy this anime, it's just that the fact that they dropped their mission to find an imposter was very annoying. If they had just ignored the fact that there happens to be an extra then I would have enjoyed this much more. But I guess it wasn't that bad.
OVERALL
It's a good show but I wouldn't watch it again. I would recommend this to mystery fans, since that's what this turns out to be.
