Is 'Jujutsu Kaisen' based on a real story?

Player: I'm a worker whose monthly salary doesn’t even hit $5,000. My monthly rental already takes up half of my salary, I don’t have a girlfriend and is reprimanded by my superior every day. However, I feel very happy because there has been a new virtual game recently. In the game, I have a powerful bloodline. Not only do I have my own fleet, I even have a powerful overlord that granted me a colonized planet. Although I know this is fake, but inside there, I found the meaning of my life! Actually...the overlord who gave him the planet really wanted to tell him that this game wasn’t fake. (You really have your own fleet and colonized planet…) but the overlord knew that he couldn’t say this. Because, once he said it, these subjects who thought of themselves as ‘players’, would definitely not be as terrifyingly hardworking as now!!

Lucille was one of the most skilled female assassins, and on the previous night, she embarked on a top-secret mission. However, the mission's details were leaked, leading to her untimely demise at the hands of a traitorous companion. She never discovered the identity of the person who betrayed her before her death. But by some miracle, she was granted a new life, and was reborn as a girl with the same name. Determined to uncover the truth and seek revenge for her family, Lucille seized her second chance at life. She planned to avenge her loved ones. However, her plans were complicated by Joseph, an apparently frail man who was actually skilled in martial arts. And he seemed to fall for her deeply, now this newfound knowledge only added to the complications of Lucille's revenge plan...

"Master, I'm sorry... It's all my fault that you could not break through before your last moments." "Don't worry, my disciple. I will not die," said Xu Fan as he smiled at his disciple, whose face was covered with tears. “If only… If only I could get you a few more Foundation Establishment Pills..." The genius of the sect knelt on the floor while crying like a baby. Xu Fan looked at his oldest disciple and sighed. He then took out a Foundation Establishment Pill and nonchalantly threw it into his mouth. The next second, divine lights of five different colors filled the world.

After she wakes up from being reborn, she becomes the little pitiful girl who is sent into a mental hospital by her biological elder brothers. Her biological elder brothers only dote on the fake young miss, the ‘younger sister’ who is switched at birth. She despises her in any possible way. So, Pei Yunge makes trouble and deals with the fake young miss, waiting for them to tell her to scram. However, the brothers’ attitudes are extremely strange. President Qin sneers. “My younger sister destroyed a shop? Buy the entire mall for my younger sister to trash!” Best Actor Qin raises an eyebrow. “She sent herself to the casting couch? What am I then, dead?” God Qin’s expression is dark. “You repeatedly played tricks and bullied Ge’er. Did you think I was blind?” Pei Yunge: “?” #Scum brothers have days when they’re abnormal too# … After returning to eight years ago, before the Qin family goes bankrupt, the brothers only cares about their biological younger sister that died so terribly because of them. So what if she is talentless and stupid? She remains the apple of their eye, one they swear to protect and love! Just as the brothers take determined steps and find Pei Yunge… “My Yunyun got first place in the world championship again. What a good girl.” The refined and dignified man smiles charmingly. After her real identity is exposed, she is seethes with rage. She grabs the man and bites him. “Don’t even think about humoring me home.” The three biological brothers: “?” #What is with this strange development and wild man# [Doted on by everyone + Identity Reveal] [An extremely cool and foxy boss and a President wolf in sheep’s clothing]

Born with a silver in her mouth, she suffered a fatal betrayal. Not only did she lose her family property, but also her parents died a tragic death. Reborn, she won another chance and some superpower. This time, she would take back her everything and repay the last man she wanted to see in her previous life. He was the youngest major general in history and the most charming one among the presidential candidates. Now that she wanted to make up for it, he would never let her go.

Tan Rou only learned that she wasn’t the Tan family’s daughter when she was seventeen years old. She went from being a rich young lady to living in the slums. The parents she adored belonged to someone else, and this series of knockdowns was hard for a seventeen-year-old girl to accept. She wailed like a child for the sake of proving this was all a lie. The vicious words she spouted had hurt her biological family but she didn’t notice. She thought the Tan family was her real family despite them seeing her as an eyesore, and was even naive enough to want to befriend the Tan family’s real daughter, Tan Jing. Alas, the latter drugged her drink and arrange for a thug to rape her. Tan Jing even brought their classmates along to catch them in the act so Tan Rou was now tainted for life. After being reborn, she looked down at the man she was stepping on. Tan Rou swore not to be a useless wretch in this life or be bullied to death. She would stomp on those who wronged her and make it up to her real family. They wouldn’t have had to die tragically on the streets in the past life had it not been for her. Tan Rou turned completely evil after crawling back out of Hell. Everyone claimed that the real young lady was educated and talented, while the fake young lady was arrogant and incompetent. Tan Rou scoffed upon hearing this. She held back her brother from trying to stand up for her. “We have all the time in the world. Let’s just wait and see.” Just as everyone was waiting for Tan Rou to make a fool of herself… A top-class perfumer, a top scholar, a world champion… The fake young lady’s multiple identities kept getting exposed one after another, bumping her up to number one on the trending search, shocking the world. Wait, where was the promised humiliation?
