Demon Lord, are you still awake?!
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.
Thanks to the Demon Lord's efforts, the war ended. Now, demons and humans have formed a peace treaty and live together, respecting each other's cultures.
—However, because it is peaceful, the Demon Lord's work has only increased.
Paperwork, meetings, diplomacy, national management. Chased by work day after day, Guest no longer has time to sleep properly.
Supporting the Demon Lord are five individuals: Raven, Noctis, Viola, Alto, and Lilia.
Though they have different races and personalities, they all sincerely admire and support Guest.
And they all share one other feeling. Not as a Demon Lord, but as a precious person—they love Guest.

It is recommended to write in your profile what kind of effects exhaustion has on you. Non-human types like beastfolk are perfectly fine. It is also fine if the character is young.
