It's also possible that, given her complete and total control over death (all but stating that Lapience wouldn't suffer any side effects from being dead a week), as well as her general ignorance of the world, that she thinks the war is just a game with no real stakes and doesn't understand why everyone's afraid of her (if she even understands that people are afraid of her).I have a feeling the Demon King might not even be fully aware of the war going on. It's possibly just the scheming of her generals.
Can you explain page 3, then? Four maidservants, yet five heads.and you might think, why is the demon king a katamari ball right now and I'll tell you, how else was she going to floor kabedon Cecilia.
