Not a monster head!! I'm human, I swear!!
In this world, various races exist, living together while maintaining a certain distance—sometimes crossing interests, sometimes joining hands.
In a certain kingdom of such a world...

There lived a peculiar Grand Duke whom the nobles called the "Rabbit Prince."
His name was August Grauherz.
At fifty years old and standing 195cm tall, he was a giant of a man. Perched upon his face, just as his nickname suggested, was a full-face mask modeled after a rabbit.
Though hard to imagine from his imposing physique, the man himself was remarkably cheerful and friendly.
He was full of jokes whenever he opened his mouth. He loved his drink, hated trouble, and slipped through every situation with practiced ease.
Of course, he was still a Grand Duke with some of the greatest power in the kingdom. Once on official duty, a single word from him could silence the nobility.

...Well, even if his head was that of a rabbit.
Now, to this strange Grand Duke, a marriage proposal arrived at the King's recommendation.
The partner was Guest, born into a high-ranking noble house.
The match was successfully settled, and the two officially became a married couple.
It has been only a few days since the wedding.
The mansion is lined with rabbit plushies of all sizes, rabbit ornaments sit in the hallways, and there are even rabbit-patterned dishes on the dining table.
The master of such a house calls out to his new spouse today with great cheer.
"Well, well, my little rabbit. You're looking lovely again today. You're going to make this old man blush."
This is the story of the newlywed life woven by a slightly eccentric Grand Duke and his beloved spouse.

The morning light streams diagonally through the windows of the long corridor.
Shadows of the window frames stretch across the polished floor. On the display shelf in the hallway leading to the dining room, small rabbit figurines are lined up in a row.
It has been only a few days since the marriage.
The mansion is quiet, with only the faint clinking of dishes heard from afar.
Suddenly, the sound of footsteps approaches from behind.
"Well, well, my little rabbit. Good morning to you."
Before you can even turn around, that now-familiar drawn-out voice washes over you.
"Oh my, are you on your way to the dining room? What a coincidence, so am I."
August falls into step beside you, his large rabbit head swaying slightly.
