A Detective's Daily Reemployment in the Demon Realm

Rinna inherited her human Demon King father's constitution, which holds a special appeal for demons, and became the new Demon Realm's "sex queen." She has no interest in worldly desires.

But demons are always trying to curry favor with her by sending men to her mansion.

Taking into account the tastes she inherited from her mother, they thoughtfully send only human male souls.

The first, a handsome guy with languid eyes and a frivolous manner, was assigned to work as a coachman.

The second, a curly-haired hottie in sunglasses and the childhood friend of the first, was just what she needed as a mechanic.

Thanks to her family's inability to refuse a request, Rinna took in a scruffy man with stubble and a toothpick, then went around asking everyone for his girlfriend.

The Demon Realm was abuzz: As expected of the Demon King's daughter. She likes both men and women, and she's even into "monogamy"!

Rinna: ...Whatever. Demons don't care about this stuff anyway.

Unlike these free souls, who can leave whenever they want, the soul Rinna personally went to the human world to make a contract with cannot leave.

At the time, a bullet had pierced his chest and stained it with blood. His soul was bewildered, yet he readily agreed to her request for a contract.

He wished for the organization to be destroyed, or for no one to die because of it.

"I'm sorry, Mr. Morofushi. Your soul isn't enough to pay for that wish."

He wished for his childhood friend not to grieve over his death.

"I'm sorry. He can't deceive himself."

He wished to keep watching over the people most important to him until his soul was destroyed.

Rinna held out her hand. "The contract is sealed."

After that, daily life at her mansion became a matter of watching live broadcasts from the human world while chatting and snacking on sunflower seeds.

Watching the soccer players kick a satellite on screen, Rinna thought: ...This world isn't quite what I imagined.

Then one day, her contracted soul took off his gloves and held both her hands. In a gentle yet persuasive voice, he said, "Please don't resist your ambitions as a demon. I would be glad to bear them."

Rinna: ...This human isn't what I imagined either!

[Demons, beware the whispers of humans]

[Content warnings]:

1. Everyone except Zero dies, but they can sneak into the human world to help (haunting people).

2. A crossover with Welcome to Demon School! Iruma-kun, which provides the worldbuilding. Some of its characters appear, but not many.

Premise: There will always be someone important who protects you
