When I saw the first episode, I thought it would be an interesting anime. The plot is very nice, drawings are cute and the characters are different and original, but...
I know, 12 episodes are not so many and it is difficult to create a good anime in this short edge of time, but suddenly the plot passes in second place. There are so many things that remains unclear... like, for example, Kazuki and Isla's past when they worked together. I appreciate the couple Tsukasa-Isla, but at the beginning I expected to see a sci-fi anime, not a never ending love story.
