This anime is one of those animes with a really good concept with cute art brought into it.
Story
The way the story was executed in the first few episodes were just fine but in the later episodes, the events were too sudden, which in a whole got me personally confused
Art
The art here is so... Kawai ( Cute ). That is all I can say to this anime. The symbols for each flag made sense too :D
Sound
I honestly have no opinion. The rating is just there because I personally liked the opening
Character
I felt like the characters were too shallow and underdeveloped before entering some crazy event, yeah sure you could say that this is how its supposed to be but the characters, if looked from a first person view didn't really have much motivation to execute the actions they did
Enjoyment
I thoroughly enjoyed the concept and art which are the 2 main reasons I gave this a 10/10
