The art and the audio are well made, however the values are feudal. If it was three years ago when I fall in love with such animation I will give it 10/10 stars(however I didn't have an account).
However, when I realized the value is actually sacrificing yourself to the land where you are born, similar to the opinion of Eastern botanical value, I would rather give it 1/10.
Sacrificing for your country actually benefits no one, only the life of yourself really matters your way.
