Transformed into a Magical Girl in a Bizarre World

[Gender swap + magical girl + female emperor romance + hard-core combat]

I'm Ling Ye, a completely ordinary guy. When I was on the verge of death in a haunted zone, I was forced to activate some kind of humiliating contract and transform into a magical girl wearing a short skirt?!

Even more absurd... after transforming, I permanently changed into a woman?!

Just as I was breaking down in front of the mirror at the sight of my unfamiliar, pretty face, the peerless female emperor who rules the Dragon Kingdom's ghost realm came to my door herself. Pointing at me, she told my older sister, “This is the bride I've been searching for for eighteen years. Today, it's time to honor our agreement.”

Me: “???”

I'm a man... no, I'm a woman now, but my preferences are totally normal!

Luckily, the Anomaly Response Bureau came knocking and offered me a package of top-tier resources. “Miss Ling Yue, join us. You can learn greatsword combat and magic, cut down as many ghosts as you like, and we'll even help keep that empress at bay.”

From then on, the city gained a magical girl wielding a greatsword.

By day, I'm the rising “Sword Maiden” of the Anomaly Response Bureau, slaying ghosts and demons and working hard to grow stronger;

At night... I have to watch out for the empress, who keeps trying to abduct me to her ghost palace and consummate our marriage.

The empress? A contract? A gender swap?

Hah, once I've completely mastered this power, it remains to be seen who's whose bride!
