The True Opening
Before we entered the Amidonia Dukedom’s Capital City 『Van』, I gave an order to the entire army.
「We will now be entering 『Van 』, however, this land is already Elfrieden’s territory. Therefore, the people who live in that city are already our Kingdom’s citizens, so I absolutely forbid any killing, raping, or pillaging. If there are people who disobey this order, then regardless of their status or position or the nature of the crime, they will be beheaded and their head will be put on display at the gates. Bear this order in mind.」(Souma)
After I gave this order, I secretly called Ludwin and handed a memo that had been prepared beforehand.
