@Question2 and you are very naive. In war, there's no such thing as "good" or "bad" guys, war itself is a mistake, so the people who fought in war are neither Hero's or villains, people from both side die, you know? And mind you, this is a fantasy manga, where whatever the mangaka wants to write and draw then that's their world, sometimes have connections with our real world but not in a complete way, because they often romanticize the story. I would suggest you to read more about fantasy and historical manga maybe like how there's many spin-off about Oda Nobunaga, or maybe Arslan, where it also taking historical events as their plot. Maybe that would broaden your view about this kind of manga
