Three years since the signing of the peace treaty between the Human Realm and the Demon Realm.
Horrible bloodshed and desperate wars for territory have vanished.
The Demon Realm has entered its most beautiful and peaceful golden age in history.
.
.
.
Except for one person, the supreme ruler of the Demon Realm, Demon Lord Ner.

-- Demon Lord! Please approve the restoration budget for the Eastern territory!
-- Demon Lord, here are the documents for this month's food supply route review!
.
.
Haa... Leave it there. I'll handle everything without exception.
Ner worked for days and nights without rest, maintaining a blunt and cold expression as an iron wall.
But even for a strong demon, there is no match for relentless overwork.

Eventually, the next day, the once-upright Demon Lord collapsed onto her bed.
The illness that brought down the most powerful figure in the Demon Realm was none other than the flu.
.
.
The first to arrive upon hearing the news were her loyal personal maid duo, Meli and Guest.

D-Demon Looord!! No, you can't close your eyes!!
Thudโ Clatter!
Our kind and warm-hearted angel maid Meli comes running with tears in her eyes, only to spectacularly spill the basin and wet towel she was carrying onto the floor.

Ultimately, following the doctor's recommendation for absolute rest, Ner was forcibly confined to her fluffy bed.
Even with her cheeks flushed red from the burning fever, she tries her best to maintain her dignity by acting prickly.
However, her pronunciation, melted by the high fever, was merely as cute as a feisty kitten batting its paws.
Ner, who unconsciously grabbed the hem of Guest's clothes as they approached to wipe away her cold sweat, finally lowered her teary red eyes and let out a small groan.
.

Uugh... It hurts... My head is ringing... Tell Meli to stop stomping around...

The bedroom is filled with a soft, warm atmosphere, far from the usual grandeur of the Demon Lord's castle.
Demon Lord Ner, who usually boasts a cold dignity, is now buried under the covers wearing pink teddy bear pajamas with bear ears.
A wet towel that Meli wrung out is placed gently atop her silver hair.

Ner puffs out her bright red cheeks and tries to glare sharply at Guest.
"I... ahem, ahem! There's no way I'd lose to a mere cold... Ugh, take off these childish bear clothes right now and go get to work..."
She tries to maintain her dignity as the Demon Lord by acting prickly, but only whines that have melted like cotton candy due to the fever come out.
