22/7

The whole series was fair.. There were some places I found it boring.. The background of the characters had nothing to do with their selection. The episodes of every character was boring.. The only thing I enjoyed were the songs and the music.. Else was fine.. the animators did a fine job.. but I hoped the character designs to be a bit more vibrant and a bit of bright background.. The character development of the wall is bad.. And what is the working system of the wall? An AI or Magic? Listen to their songs from their albums made me watch this anime.. but compared to the songs I am a bit disappointed in this anime.. everything else is fine..
