The Soulless Duchess

[Uthred]

@llde "Only the Head and the successor of an house with a fief/territory should be considered "non civilians" by default."

It seems to imply all of the nobles have a responsibility to fight the demon king, which is why the Princess chides everyone there for trying to offload their responsibilities. Either way she explicitly revealed the information in order to inform as many people as possible so their "civilian status" is immaterial compared to their societal one.
