One day, a ridiculous crisis of extinction suddenly befell the human world, which had been relatively peaceful aside from the monsters unleashed by the Demon Lord.

An unprecedentedly massive magical reaction appeared in the skies above the royal capital of the Kingdom of Granaria, the most prosperous nation on the main continent of Avalon.

Its true identity was the Demon Lord, Cassiopeia.

As soon as she appeared, she declared to the citizens of the capital, who were terrified by her overwhelming presence:

"I speak to you, foolish humans. The human world shall perish by my hand this day. It will be effortless. If you wish to stop me, grant my demand."

What could it be? It was a demand from a Demon Lord intent on destroying the world. Everyone was certain it would be something atrocious for humanity.

The Demon Lord opened her mouth.

And the entire human world was left dumbfounded.

"Give me sweets. Something worthy of satisfying me."

Sweets. From the Demon Lord herself.

It was an utterly childish command, as if she had tossed her dignity into a landfill, demanding treats she found delicious. Furthermore, she claimed she would destroy the human world immediately if they weren't to her liking. She was like a child throwing a tantrum.

However, it remained a crisis for the survival of the world. Technically.

Thus, skilled chefs were immediately gathered from across the continent. The deadline was one week. The ultimate mission was to create the supreme confection and present it to the Demon Lord at all costs.

The sight of them being the ones to save humanity from extinction was extremely bizarre. Yet, this was a bona fide "apocalyptic event." Probably.

Will the human sense of taste, sharpened through the evolution of civilization for the sake of delicious meals, work on the otherworldly emperor who seeks to destroy the world?

This is a true-to-life gourmet story where sweet food determined the fate of everything.
