Kazuki Tanaka is just an ordinary convenience store clerk living a peaceful, predictable life in the quiet town of Midori. But everything changes when Lilith, a stunning yet terrifying demon princess, storms into his store, mistakes his mop for a legendary sword, and declares him the “Great Hero” who defeated her father. To seal a peace treaty between the human and demon realms, she proposes marriage—on the spot.

Before Kazuki can explain the obvious misunderstanding, Lilith puts a magical engagement ring on his finger, binding him to a contract he can’t escape. Now, Kazuki must survive life as the unwitting fiancé of a demon princess while the real Great Hero desperately tries to undo the mix-up.

Caught between otherworldly politics, comedic misunderstandings, and his new fiancée’s relentless determination to win his heart, Kazuki’s simple life is over. But hey, at least he still has his mop.

The Demon Princess Wants to Marry Me, But I'm Just a Shop Assistant

I accidentally defeated an assassin with my mop.Now, everyone thinks I'm some kind of combat prodigy.As a result, I've been thrown into a training session straight out of a nightmare.

Conclusion? I'm still gonna die.

I stood in the middle of the training field, gripping my mop like my life depended on it. (Because, y'know, it did.)

Surrounding me were six moving training dummies. Each one was armed with actual weapons.

One had a flaming sword.

Another had a crossbow loaded with arrows.

And one of them, for some reason, was just on fire.

I turned to Lilith. "Uh, Princess? Don't you think this is a bit… much?"

She smiled. "Nonsense! A hero must overcome challenges to grow stronger!"

Ryuu crossed his arms. "Yeah, but he's NOT A HERO."

Vorthrak, the terrifying demon general, stepped forward. "Begin."

The dummies attacked.

Kazuki vs. The Killbots

The first dummy swung at me with a flaming sword. I screamed and rolled away.

The second dummy fired an arrow. It missed my head by half an inch.

The third dummy exploded.

"WHY DOES IT EXPLODE?!" I shrieked, dodging the fiery blast.

Lilith clapped. "Excellent reflexes, my love!"

"STOP CALLING ME THAT AND HELP ME!"

I dodged. I rolled. I swung my mop wildly. By some miracle, I managed to hit one of the dummies in just the right spot—

It fell apart instantly.

Lilith gasped. "Ah! He discovered the weak point!"

Ryuu stared. "No, that was just dumb luck."

But the demons watching started cheering.

I collapsed onto my knees, gasping for breath. "I… I survived?"

And then he gestured to another row of dummies.

WHAT DO YOU MEAN 'NEXT ROUND'?!

The Aftermath (And My Recovery Snacks)

That's how long they made me fight those stupid dummies.

By the end, I was covered in bruises, burns, and pure regret.

Lilith was thrilled. "You did wonderfully!"

Ryuu sighed. "He got hit forty-six times."

Lilith nodded. "Yes, but he survived."

I groaned. "That's not an achievement!"

As a reward for my suffering, I was given a plate of mystery demon food.

I stared at the purple, glowing meat. "…What is this?"

Lilith beamed. "Demon Boar Steak! Very nutritious."

Ryuu leaned over. "It bites back."

Lilith pouted. "Oh, don't be dramatic! Here, I'll feed you!" She grabbed a piece and held it up.

The entire room stared.

Ryuu looked horrified. "What. Are you. Doing."

The demon nobles whispered excitedly. "She's hand-feeding him!"

I felt my soul leaving my body. "I… I can feed myself, thanks."

Lilith smirked. "Oh? Are you shy?"

I grabbed the fork and shoved the food in my mouth just to end the embarrassment.

Lilith clapped happily. "See? Now, eat up! You need strength for tomorrow's training."

Lilith smiled sweetly. "Of course. You must become strong enough to defeat the next assassin."

My stomach dropped. "Wait… NEXT assassin?!"

Lilith nodded. "Oh yes. That one was just a scout. I expect stronger enemies soon."
