What is Feudal Warfare manga?
Feudal Warfare is the warfare of the Middle Ages and therefore the setting must take place in a time line similar to that of Middle Ages or its Asian/American counterparts, or in a fantasy world. Generally it can be described the same way as the Military category, just that the weapons used are swords, spears, bows, catapults, cannons and other weapons used in the Middle Ages. Note: Just because the anime contains a guy or a couple of guys with swords wondering about, doesn't make it applicable for this category, unless there are larger military organizations/groups involved in armed conflict with each other, you might not want to add this genre.
