Anything Can Happen at Seventeen in the World of Detective Conan, But Not a Sex Change

In the first timeline, something went wrong with the world. Ran Mori lost her childhood friend, her parents, and her friends Sonoko and Masumi, who had taken her out to cheer her up. Only she was rescued by Vermouth from the building that burned to ruins. When she woke up in the hospital with nothing left, she asked Vermouth, "Can I join you?" Thirty years later, Black Ran, who had outlived Renya Karasuma and Rum, became the Organization's boss. Shiho and Noah's Ark successfully developed a prototype "time machine." Black Ran got in and returned to Tropical Land, where Shinichi had died thirty years earlier. Reason told Black Ran she should stop Shinichi from investigating Gin and Vodka, so he wouldn't be forced to swallow the poison. But she really wanted to ask Shiho what she'd put in the time machine to make her undergo a painless sex change. I know that turning seventeen might bring a series of life-changing upheavals, but... Please, a sex change shouldn't be one of them! Important: 1. Ran is an angel. Black Ran is my own headcanon. 2. In the second timeline, the Organization's boss is Black Ran, not Renya Karasuma. 3. Just a plot bunny. Theme: Growing together
