The Demon King Keeps Trying to Do the Unspeakable with Me [Western Fantasy]

Eve transmigrates into a steamy Western fantasy novel and becomes an unnamed background character.

In this world, people can summon a contract beast of their own when they come of age. Contract beasts tend to have something in common with their masters, whether a love of sweets or a passion for adventure.

Eve rubs her hands together, hoping to summon a mighty, powerful contract beast and change her fate as a background character.

But with a flash of white light, a little creature appears in her arms... a demon cub with a pair of red horns and a heart-shaped tail swaying lazily.

It is powerful, all right, but how did she summon the Lord of Hell?!

Thinking of the terrifying stories about the demon king's countless murders, Eve wants nothing to do with a contract with the demon cub. She just wants to run away.

The Lord of Hell clicks his tongue in displeasure, transforms back into his adult form, pins Eve against the wall, and forces her into a master-servant pact.

Eve, forced to sign the contract, gazes at him with tearful eyes. Who can tell her what this handsome, cold-hearted demon king has in common with her, a comedy-loving girl who adores internet memes?

The demon king tilts his head and reads her thoughts.

His thin lips part, and the words he says leave Eve stunned for a hundred years: "If we have nothing else in common, then we both enjoy things meant for adults."

Eve, who transmigrated into a book because she read steamy novels: ...I think he might be right.

After entering the Royal Summoner Academy, Eve dutifully raises her demon cub, praying that once the demon king has had his fun, he'll return to Hell on his own.

But her inconspicuous background-character life has been completely upended.

A pompous professor mocks Eve for being useless. She grits her teeth and puts up with it.

Her noble classmates look down on her lowly origins. She presses her lips together and accepts it.

Her academy classmates secretly gossip that Eve's contract beast is a useless little cub that can't fight. Eve whirls around in horror and punches the gossiping student into the ground.

Shut up!! If we make the demon king angry, we'll all die!

The demon king raises an eyebrow, returns to his adult form, and kisses Eve's fist.

He looks at the people doubting his abilities. "Why don't we take this to bed and see just how good my master and I are at fighting?"

My take on Western fantasy, not a typical academy story, lighthearted tone.

A timid girl who loves running her mouth × the Lord of Hell, whose old heart is thawing.

One-on-one, both exclusive.

Theme: Be a good, upright person
