Are There Any Spin-Off Mangas For Swindle Book?

On the day I return to my home to reunite with my actual family, Melanie Stewart, the fake heiress, shows up in front of me. Her neck is completely riddled with hickeys. Instantly, countless live comments appear in the air around me. "Poor Yvonne! She thought she could start living a comfortable and lavish life now that she had been accepted by her actual family. Little does she know that Melanie has already formed a pact with the transfer system!" "Melanie is a loose woman by nature, and she loves sleeping with countless men. After getting bound to the system, the children she gets pregnant with will be transferred into Yvonne's womb instead." "Yvonne will proceed to give birth to dozens of bastard children, thus humiliating her family to no end. She ends up getting cast out of her family by her own parents!" "The truth is, there's a solution to this situation. Yvonne can just remove her uterus so that the system won't work at all. Alas, she doesn't know about that." I stop in my tracks at that moment. In my previous life, I had believed the live comments. As such, I traveled to a hospital to get my uterus removed overnight. But the next day, Melanie blew the whistle on me to my parents. She claimed that I wanted to get rid of my uterus in order to cut down the risks completely for the sake of having as much fun as I wanted with other men. My parents were completely disappointed in me. My fiance refused to enter a marriage alliance with me, a woman who could no longer give birth, as well. In the end, I died from a post-surgical infection. However, Melanie obtained everything that was supposed to be mine, to begin with. That was how she became successful in life. When I open my eyes again, I realize I've returned to the day I'm bound to reunite with my family.

A week before the college entrance exam, my twin brother, Tristan Doyle, runs away with a delinquent. Our parents abandon their massive corporate empire and set out to search for him. I intend to join the search, but a comment abruptly flashes across my vision. "Don't go, Ryan! If you skip the exam too, your family is doomed!" With no other choice, I shoulder the pressure and walk into the exam hall alone. Yet the moment the exams end, my parents return and lock me in the basement. Ten years later, I finally escape, only to discover that Tristan has stolen my identity. He's celebrated as that year's top scorer, gets a degree from a prestigious university, and is even married to my former high-achieving girlfriend, Alisha Hudson. They share a perfect life with two children. Furious, I attempt to confront them, but they bind me and throw me back into the basement. As I howl in rage, my parents reprimand me, "Tristan was never as smart as you, and that delinquent tricked him into running away. There was no way he could've gotten into college on his own." "You're his older brother. What's wrong with letting him have one thing? Stop being so selfish." I break down completely and die in despair. Only after my death do I learn that Tristan was the one who sent that comment. When I open my eyes again, I'm back on the day Tristan elopes with the delinquent. The comment appears once more. As I stand there frozen, Alisha gently nudges me with a smile. "Go study! Your whole family's counting on you."

A thirty-year-old office lady, who got into an accident and is now trapped inside a novel series she loves. She was reincarnated into one of the side character extras of the story and meets in person the tyrant magician, the playboy prince, and the clueless female lead of the story.

At my 20th birthday banquet, I am to sign and receive the ten-billion-dollar inheritance left to me by my mother. My half-sister, Samantha Hatfield, and Howard Daley, her husband, who is also a secretary, eagerly urge me to sign the document. In my previous life, they trick me into signing the very same agreement, and the inheritance somehow becomes theirs. When I try to fight back, no one listens to me. Together, they have me confined to a sanatorium, where I spend the rest of my life drugged, imprisoned, and forgotten. But this time, their scheme is going to fail—I have returned with memories of what happens from the past life. Under their confident, expectant gazes, I pick up the pen. However, I do not pick it up to sign. I raise my hand and slash the pen's tip across Howard's face. As he lets out a terrified scream, I tear the agreement into pieces in front of all the guests and hurl the paper scraps at them. I say coldly, "My mother left all this to me. What makes you two heartless parasites think you're worthy of laying even one finger on it?"

One moment I'm chasing after a rabbit and the next, I'm falling down a rabbit hole! What the heck?! This ain't Alice in Wonderland?! Though as I opened my eyes, I soon found out that I was no longer in my original body and that somehow I transmigrated into the light novel, A Fairytale Romance. And that isn't all, the character whose body I transmigrated into... is none other than the canon-fodder, stuck-up, arrogant, and selfish ojou-sama who was nothing more than a comic relief character, Maria Rosendrey. Life truly sucks...

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!
