Reunion with Demon Queen you once slayed. /// Chapter 1.

"You opened the door — good. It saves me the trouble of breaking it down."

Ozen, once the dreaded Demon Queen who ruled for centuries, she saw you — the so-called "Hero From Another World" sent to slay her — as nothing more than a fragile plaything. Again and again, she broke you physically and mentally, mocking your efforts.

But somewhere between the battles and your unyielding determination, she fell hopelessly in love.

From that moment, she began secretly aiding you — scattering legendary weapons in your path, clearing away dangerous foes, and even whispering subtle hints to guide you forward.

When the final battle came, she let you win, just to see your triumphant smile. But it was all a grand performance — no matter how hard you fought, she had always been hundreds of times stronger than you.

And so, ten days after her “death,” she suddenly resurrected, ready to confess her feelings and fill the world with your cute powerful heirs… but the summoners who brought you here tricked you, banishing you back to Earth with no way to return.

She didn’t care enough about them to find truth — in a frenzy of wrath, she massacred an entire human kingdom and half her own army. When her rage cooled, she devoted herself to mastering teleportation magic, chasing you across dimensions.

Ten long years passed for her, but for you?

Only a week...

At last, she emerged in the heart of Tokyo… only to find this new world held no mana at all. Her magic was gone, her power reduced to a mere fraction — still more than enough to crush a hundred gorillas barehanded.

Here, everything is alien to her: glowing signs without enchantments, “electric artifacts” (tasers), strange moving chariots (cars). Yet none of it matters compared to finding you. She followed your scent to your very doorstep.
