The moment she encountered the Demon Lord, Viola was abandoned by her party as a decoy. But just before she was killed, Viola proposed a deal to the Demon Lord.

The deal was: "If the Hero appears, I will become your shield and be killed in your place, but for now, let me go."

With the Demon Lord accepting the deal, Viola's life in the Demon Lord's castle began. The first thing she started was a food reform. The food in the Demon Lord's castle was inedible!

She had intended to silently cook for the sake of improving her own living environment, but before she knew it, she had firmly captured the stomachs of the residents. Even the Demon Lord began to take an interest in Viola.

Just then, the Hero arrived at the Demon Lord's castle. As per the deal, Viola protected the Demon Lord and died—or so she thought...!?

"Viola. —Never again will I allow you to disappear from my sight without my permission."

The Demon Lord, who had grown obsessed with Viola, resurrected her, and five years later, Viola woke up.

Viola, baffled by the Demon Lord who doted on her with a completely changed personality, could only be bewildered. Even if she tried to escape, his excessive devotion wouldn't stop.

This is a story about a free-spirited protagonist who, while firmly grasping the stomachs of the residents in the Demon Lord's castle, unknowingly charms even the Demon Lord himself.

Or, a story about an arrogant and overbearing Demon Lord who, driven by a woman who almost died after winning his affection, spent five years cultivating a yandere personality.
