I'd Still Rather Be the Greatest Under Heaven

[I'm planning another two-word-count preview, The Ability Is Random Ex-Boyfriends Transmigrating Back. The blurb is at the very bottom~] You have a secret. Since birth, you've been able to see the monsters wandering through the city, and strange voices sometimes flash through your mind. After graduating from elementary school, your beloved Guardian Egg disappeared. You moved away with your family, and the System, which had been playing dead for years, finally came online. So you quickly accepted your role as the heroine of a hot-blooded manga and began an otherworldly adventure, all while your neighbor, Saiki, watched you with an unsettling look. After learning Moon Breathing from your master, you planned to carry on his dream of becoming the strongest in the world. But just after leaving the beginner village, you were defeated by a brat who looked a lot like him. Just when you thought life couldn't get any darker, you took your frustration out on monsters in the real world and got soundly beaten by a nasty white-haired, cat-eyed jerk. You swore that one day you'd smash that arrogant face of his. To fulfill your dream of becoming the strongest, you accepted the jerk's invitation to become his classmate. Thus began your diligent routine of studying jujutsu during the day and practicing breathing techniques at night. Later, you discovered that sleeping with the strongest was a lot faster than becoming the strongest. Cheerful laugh.jpg _ At twenty-eight, Gojo Satoru had a wonderful life. Then he transmigrated with his best friend and colleague, and somehow turned into an egg. As for who the egg belonged to... Young Master Gojo made a sudden realization: “Could this be the source of the so-called magical girl technique?” At twenty-eight, Geto Suguru, a teacher at Jujutsu High, transmigrated. Along with the rival he'd just had an argument with. He had no idea what a Guardian Charm was, but it seemed to be something like a spirit guardian or whatever. At this point, who could deny that they were childhood friends?! _ Seven-year-old Tsugikuni Yoriichi had not yet lost his mother or left home. He saw someone fall from the sky into his room and made his first friend since he could remember. Seven-year-old Tsugikuni Michikatsu had no idea he'd lose his status as heir. He saw a girl suddenly pop out and point at his father's nose, calling him an old bastard and saying that a man who emotionally abused his wife didn't deserve to live. Twenty-seven-year-old Tsugikuni Michikatsu had already become a demon. He took on a new disciple. His disciple was a girl with great talent. It took her only three months to master Moon Breathing. But when she came back from an outing, she started crying to him, asking if there was any hope for her when she couldn't even beat a seven-year-old. He had high hopes for her. Then one day, the disciple he'd carefully raised showed up with the younger brother who should have been dead. “Teacher, look who I brought to meet you!” “...” [Tips] The main story is written in second person. Features Haikyuu!!, The Disastrous Life of Saiki K., and Inuyasha, but they don't get much plot time. Jujutsu Kaisen and Demon Slayer are the two main storylines. A happy-ending, everything-gets-wrapped-up story. Treat anything that doesn't match canon as an alternate setting. Love you all (˘³˘)♡ The blurb for The Ability Is Random Ex-Boyfriends Transmigrating Back starts here As an ordinary Demon Slayer Corps member, you awakened a strange ability a long time ago. Every night, you dream of a different life. Some take place in Heian-kyo a thousand years ago; others in a dazzling, beautiful world a hundred years in the future. The feelings you couldn't tell anyone about didn't actually affect your life. That is, until one day, your dream boyfriends came crashing down from the sky And everything went wrong. Today, one person patiently teaches you how to use the powerful elite to deal with your archenemy, the Demon King. Tomorrow, someone else boasts that he's the strongest and can easily solve all your problems. The day after, another one smiles shyly and offers to help you improve your Breathing Style. A different one every day, with no days off. If that were all, it wouldn't be so bad. But as time goes by, your fellow Corps members start looking at you strangely. You're really not some strange woman who toys with people's feelings. [Tips] Second-person narration. You love them all. Childhood sweethearts are the best; don't ask how many there are. You have some morals, but not many. You're that kind of wicked woman: falling in love with everyone you meet is only natural. Some characters who died in canon will be saved. The cast list features the male leads (may change before the story begins). Koyoharu is platonic. The main world is tentatively Demon Slayer. End of preview blurb Theme: Keep working to become a better version of yourself.
