How Does Gender Swap Work In Anime And Manga?

My half-sister and I were both married on the same day. She was supposed to be sent away to a distant kingdom as a peace offering, branded with an ill-fated destiny. I was supposed to marry the Crown Prince and become the future queen. Yet the night before our weddings, my stepmother orchestrated a switch. In my previous life, I stormed into the wedding ceremony desperate to expose the truth. My sister immediately threatened to kill herself to prove her innocence. The Crown Prince caught her just in time, but the shock caused her to lose the baby she claimed to be carrying. The Crown Prince was furious. He accused me of fraud and attempted murder of the royal heir. He ordered my head shaved and my face mutilated before having me thrown into the peace bride's carriage. I became the laughingstock of the entire capital. My half-sister took my place as Crown Princess, gave birth to twins, and eventually became the beloved empress. Meanwhile, I died on the road to that foreign land. When I opened my eyes again, drums and music thundered outside. The wedding procession was already waiting. A voice rang out, "By royal decree, we have come for the bride!"

The first thing I do after being reborn is secretly keeping six stunning male models behind my wealthy husband’s back. I seduce them and sleep with them for 999 days to get myself pregnant. I do all this because in my past life, my husband found out that he had asthenozoospermia and married me because I am known for being fertile. He wants to carry on the family line so that he will have a successor to inherit the family fortune. I try everything I can to get pregnant, but nothing works. Conversely, my infertile best friend gives birth to twins and triplets within two years after marrying a 70-year-old man. When my wealthy husband hears that my best friend is blessed with children, he is immediately captivated. They get together behind my back and even arrange for someone to run me over with a car when I find out the truth. After my death, I discover that my best friend has bound herself to the child switch system. Any child I am impregnated with is transferred into her womb. My best friend's infertility is transferred to me in return. When I open my eyes again, I find myself back on the day when my husband married me and brought me home. I smile happily when I think about all the things that took place in my past life. My best friend wants lots of children, doesn't she? If so, I will make her experience the joy of having 18 babies in one pregnancy!

My husband Norman had always hated how his childhood friend Julia clung to him no matter the occasion. He even cut her off for my sake. One morning, I woke up and realized that I had mysteriously swapped bodies with Julia. I wanted to find my husband and figure out what to do, fearing he'd turn me away because of Julia's appearance. I cooked up a hundred explanations in my head until I finally arrived at our home. When Norman opened the door and saw me, he frowned and quickly shut the door, pushing me away. Just as I was about to explain that I wasn't Julia, he suddenly pulled me into his arms. "What are you doing here? Can't stand being apart from me for even two days, huh?"

After transmigrating into a novel, I realized the heroine and I had the exact same name. Naturally, I thought I had transmigrated into the female lead. So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me. He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing. Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me. Heartbroken, I packed my bags and got ready to disappear. The next second, he pinned me against the wall. "Where are you going? Already bored of me, sweetheart?"

My mother, Eleanor Leigh, is pregnant with fraternal twins, but we aren't developing well. The doctor recommends terminating my younger sister, Juliette Vance, whose chances of survival are slim. Since Dad, Thomas Vance, suffers from azoospermia and can never have children again, I, Julian Vance, become the pampered, only child of the family. For my first birthday celebration, Mom and Dad gift me a house and a vehicle. Every day, they dress me up like a porcelain doll and specifically enroll me in ballet classes to elevate my poise. They even carry me everywhere I go, terrified that I might fall and end up with a scar. I only learn I'm a boy in elementary school when I get laughed at for entering the girls' restroom, and later learn it in a science lesson. Because of my classmates' constant bullying, I break down in tears, begging Mom not to make me wear dresses anymore. However, she, who is usually so gentle with me, suddenly flies into a rage and slaps me hard across the face right in the middle of the street. "What's going to happen to your sister if you don't wear dresses? It's your fault for being born a jinx! You killed your sister! "If you hadn't stolen her nutrients, she would be alive and well right now! Our family business would be booming as well. You'll either be our daughter for the rest of your life, or you can go to hell right this instant!" It turns out Juliette and I are the children Mom and Dad begged the heavens for, and while Juliette's a lucky charm, I'm a jinx. I wear long hair and dresses because I'm Juliette's body double. I sprint away in tears, only to be sent flying by a car running a red light. As my consciousness slips away, I wish with all my heart to go back to when Mom first found out she was pregnant. This time, I'll be the one to be reduced.

After being reborn, the first thing I did was switch my newborn daughter. In my previous life, soon after she was born, a blood test showed her type was AB. But mine was B, and my husband's was O—there was absolutely no way we could have an AB-type child. My husband flew into a rage and demanded a paternity test on the spot. To everyone's shock, the results proved she was biologically related to me, but not to him. He slapped me hard across the face, his voice trembling with disappointment. "I've always treated you well. I only ever loved you—and this is how you repay me?" My mother-in-law wailed and cursed me for cheating, accusing me of bearing another man's child to steal their family fortune. I was completely stunned. I knew better than anyone who the father of my child was—how could she possibly not be my husband's? In no time, everyone turned against me. They called me a cheater, a tramp. My husband divorced me and went online to play the victim, stirring up a storm of hate and harassment that never seemed to end. With nowhere to go and no one left to believe me, I took my baby in my arms and jumped from a building. Even in death, I couldn't make sense of it all. And when I opened my eyes again, I was back on the day my daughter was born.
