This is the animation of the browser game though the story in the anime is not clearly portrayed. Many parts of the story are skipped that will end you up to being curious on what is the story. If you are interested in the story of this series, I recommend that you should play the game on what really is happening on each episode of this anime although it would take some time. The story mode of the game is like a picture drama with you as the captain(Gran). You can choose whether you Autoplay the story or skip and read the summary. Note: Applies onthe anime only and not in the game.

Story: 6/10-the story is not portrayed that clearly in this anime leaving questions to those who are foreign to it.
Sound: 10/10 The soundtracks are composed very well. Hint(Nobou Uematsu is one of the composers)
Character: 10/10
Enjoyment: 7/10
