Becoming the Jujutsu World's Villain and Knife-Wielding Menace

[Recommended: Pre-Release for My Spin-Off, "To Retire, I Put On a Tragic Beauty's Secret Identity"] The Tsukishiro family is a talisman-making clan outside the Big Three, and the best support a sorcerer could ask for. Their bloodline descends from Lord Tengen. Legend has it that the Tsukishiro family's inherited technique can draw talismans capable of truly devastating the heavens and earth. There are also rumors that... Anyone who possesses the Tsukishiro family's inherited technique can turn others into the "strongest." Tsukishiro Kiri, the first child in nearly a century to inherit the family's technique, was hailed as the "Holy Child." Like an ice lotus in the snow, he seemed beautiful yet untouchable, and countless people coveted his talismans. After being bound to a manga System and learning the future of the people he cared for and loved, he refused to accept that ending. So he took that first step. I don't care about "angst points" or the plot. I just want them to have a happy future. [The Nameless] "Once you formally accept the System, if you fail a mission, then both the Tsukishiro family and Tsukishiro Kiri will be completely erased from this world. They will cease to exist." "Isn't that wonderful? Someone who had nothing to begin with won't ever loosen their grip on the light, no matter what." [Shattered] Scarlet runes rose into the air, and the ritual array activated. The teacher Suguru Geto trusted most trapped him inside it and plunged a blade into him without mercy. "Why?" "Someone has to do it. Let me be the one. Stop being so naive, Suguru." Special Grade sorcerer Tsukishiro Kiri officially defected on July 9, 2007. Tsukishiro Kiri set out on a road with no turning back. Even knowing that the end held horrors unknown, he did not hesitate. [Slow Death] "The price of changing the world is more than you can bear." "Whatever the cost, whether it's being forgotten and doubted, illness and loneliness, or even death, nothing can stop me." I want the people I love and the people who love me to have a happy future. For that, I'm willing to give everything. [Every Beginning Has an End] He leapt from the tower. As he gazed at the azure sky, he thought of the person he loved and all the beautiful times they had met and come to know one another. The worst curse user is defeated, and everyone gets a happy ending. It couldn't be a more perfect story. "Everyone will have a happy future. The road ahead will surely be bright and glorious." See? I did it. Important notes: No content theft protection. Thanks to everyone who supports the official release! The protagonist is a tragic beauty: this is a cliched story about a beautiful, powerful, tragic, sickly, cold beauty who suffers physically and emotionally! Pairing with Gojo. Happy ending, and I will kick the can back down the road (not a single one of them is allowed to die!) OOC warning. The timeline is chaotic, with original setting details. What if both of them were teachers? Suggestions are welcome, but please don't flame me. The author is sensitive. The next pre-release, "To Retire, I Put On a Tragic Beauty's Secret Identity," has the following synopsis: Chidori is a cleaner in the Secret Identity Department of the New World Bureau. Not just any cleaner, either. He specializes in cleaning up damaged SSR cards. He only needs to work for another three hundred years, and then he can retire and be free! One day, while diligently cleaning out a card pool, he encountered an unknown space-time black hole. In the desperate moment, all he could do was grab a few cards nearby and get sucked in with them. Just as Chidori was happily thinking he wouldn't have to work anymore, his busted old System told him that if he didn't hurry back, he'd have to work several hundred more years before retiring. Chidori, who had signed away his freedom: … "But didn't you grab a few secret identity cards? We're the Secret Identity Department. Once we finish the missions and build up enough energy, we can go back!" the System said excitedly. Seeing that Chidori still wasn't motivated, it added, "There's a chance this could shorten your time until retirement." "Let's go! Hurry up! What are you standing around for?" Chidori sprang into action. [The Sickly Gravity Manipulator Who Lost His Ability] In everyone's memory, Nakahara Chuuya was always free and flamboyant, overwhelmingly powerful on the battlefield. Now, however, illness shadowed his features. His icy blue eyes had grown dim, and even a breeze left him coughing uncontrollably. "Cough... Hey, hey, don't look at me like that. Even like this, I can still kill you." Watched by his partner with a complicated expression, he spoke haughtily through a cough of blood. [The Strongest Sorcerer, Blind in Both Eyes] A grown-up Gojo Satoru claiming to be from a parallel world arrived in this one. Like attracts like. He and sixteen-year-old Gojo Satoru became buddies, arms slung over each other's shoulders. They all thought this Gojo Satoru's future would be bright and dazzling, and that he would always be the arrogant strongest. Until the bandages slipped, revealing those lifeless Six Eyes. [The Officer Struggling in the Abyss] Officer Matsuda, who had sacrificed himself for the public good, appeared again one spring day. Everyone thought it was a conspiracy. Only his childhood friend, with violet eyes, held on to his hand and refused to let go. "Why have you come back?" "To fulfill my duty as a police officer, and for my friends who died." So he could do anything, and accept any identity, to make that happen. [The Lonely, Gloomy World's Greatest Detective] A traveler who had lost everything arrived in a world both familiar and strange. If not for that identical face and his own confirmation, no one at the Detective Agency would have believed the person before them was the proud great detective. He lowered his eyes and put on the same childlike smile as Ranpo in the original world. He could even fool another version of himself who could see the truth of everything. It was almost as if this version really were the great detective everyone doted on. Look at me, the proud and confident me. Don't look at me, the worthless me. People from every world: What on earth happened to you?! QAQ Chidori, overcome with sorrow and resentment at the thought of having to wait several hundred years to retire: ?
