In a Strange World, Transform into a Magical Girl

[Gender change + magical girl + empress stickers + hardcore fighting] I, Ling Ye, a pure man, was forced to activate some kind of shameful contract when I was dying in the ghost zone - transformed into a magical girl wearing a short skirt? ! What's even more outrageous is... After the transformation, I actually turned into a woman permanently? ! Just when I collapsed in front of the unfamiliar pretty face in the mirror, the peerless empress who ruled the ghost realm of the Dragon Kingdom came to the door in person, pointed at me, and said to my sister: "This is the bride I have been looking for for eighteen years. Today, it is time to fulfill her promise." Me: "???" I am a boy... Oh no, I am a girl now, but my orientation is normal! Fortunately, the Abnormal Bureau came to my door and gave me a set of top-notch resources: "Miss Lingyue, join us. You can learn the big sword, magic, slash ghosts, and help you block the empress." From then on, there was a magical girl with a big sword in the city. During the day, I am the rising "Sword Princess" of the Yi Tiao Bureau, slaying ghosts and demons, and working hard to become stronger; At night... I have to beware of Her Majesty the Empress who always wants to kidnap me back to the Ghost Palace to consummate our marriage. Empress? Contract? Sex change? Oh, when I fully control this power, it's not yet certain who is whose bride!
