"Gankutsuou: The Count of Monte Cristo" and "The Heroic Legend of Arslan" / "Arslan Senki" both involve a young and naïve male protagonist of high birth who lives in his powerful father's shadows.
In both these shows, military campaigns are given a relatively heavy focus as the background in order to set the premise.
