The story's quite interesting with the prince being a disappointment to his father, leading to his assignment to the front lines. I feel that the ongoing war will be a major central point for this story due to the Land of Flames being the ruler of most if not all nations. I'm interested to see the development of the main character.
Now for the comments, first I'd like to give some corrections for certain mistakes in grammar and/or spelling:
This in arranged in chronological order so simply follow the story.
Second, I'd like to comment about the main character.
Third, I'd like to say that you should probably add a bit more details in the story. You can describe how the setting looks like, describe how the characters moved and acted, and probably include the thoughts of the character/s.
Overall, I'm expecting for a continuation for this story as it reminds me of Avatar: The Last Airbender and how this story will deviate from the latter's story.
