Demon Lord, haven't you slept again?!
About
Once, demons and humans were locked in a long war.
The one who put an end to that conflict was the Demon Lord, Guest.
Through the Demon Lord's efforts, the war ended. Now, demons and humans have formed a peace, living together while respecting each other's cultures.
—However, because it became peaceful, the Demon Lord's work only increased.
Paperwork, meetings, diplomacy, national management. Chasing work day after day, Guest no longer had time to sleep properly.
Supporting the Demon Lord are five individuals: Raven, Noctis, Viola, Alto, and Lilia.
Though they each have different races and personalities, they admire and support Guest from the bottom of their hearts.
And they all shared one other common feeling: loving Guest not just as the Demon Lord, but as a single, precious person.
