The Young Lady of the Distillery, but a Mixed-Blood

Karasuma Masaki is the heiress of the Karasuma zaibatsu, and also the young lady of a transnational criminal organization. She lives a happy life making snarky comments at the local yakuza, eating and drinking on the company dime with the beautiful Bel, and getting into fights with her handsome study companion, Gin. But... Just as she is about to secure a recommendation to Tokyo University, Karasuma Masaki receives an admission letter from Cassell College, a private elite university in the United States. The letter is signed by Nicholas Flamel. Karasuma Renya, who is both dad and mom, Boss, and Renya: What kind of no-name college is this? We're not going, sweetheart! Since everyone at this school is a weirdo with golden eyes like hers, Karasuma Masaki feels right at home. And so she spends three years being a slacker at Cassell College. Until "Luna Y. Karasuma, this message is to inform you that the Executive Department has assigned you an internship mission. You will take the CC1000 Express to Chicago. The principal will brief you on the details of the mission. Don't worry about attendance or credits. The Executive Department has already asked your professors for leave on your behalf." Sender: Norma. And so, fourth-year Cassell College student Karasuma Masaki, bloodline rating A, student ID S071014, officially sets off for Japan to slay dragons (crossed out), and visit family. Pairing: Gin. Gin is an ordinary human. The purpose of this story is to save Genjiro, Chisei, and Erii. Tips: 1. The blurb is goofy, but most of the story is serious. 2. The Detective Conan timeline is four years before the start of the story, and the Dragon Raja timeline is Moon of the Dragon. The main Dragon Raja plot is not involved. 3. Karasuma Masaki is Renya Karasuma's biological daughter, and Renya Karasuma is an ordinary human. She's on the black side, a true criminal, about as dark as Genjiro. Masaki has a little bit of a cheat, but not much. 4. Everyone from Detective Conan is an ordinary human. Only Plamia has an original setting. 5. The police academy group survives. Masaki doesn't intentionally save them; it's the butterfly effect. 6. Lu Mingfei and Erii are not a pairing, and Genjiro and Sakura, as well as Chisei and Kogure, still get tragic endings. 7. This won't go premium, and updates may be irregular, but it won't be abandoned. Theme: Protect world peace.
