Transmigrating into Detective Conan: One Superpower a Day

A ridiculous overtime accident sent Shangguan Tianyi straight into the world of Detective Conan. When he opened his eyes again, he had not only become a silver-haired girl named Amamiya Yumi, but had also unexpectedly acquired a mysterious System that only he could know about. He thought life after transmigrating would amount to going back to school and watching Shinichi Kudo solve cases. But before long, she discovered that her other identity was a member of the Black Organization, codename: Merlot. What's even more absurd is that this identity seems to be no ordinary one. She is a skilled doctor with all kinds of special abilities, and can move freely in the Organization's bases. Even Vodka instinctively takes a few steps back when he sees her, while Gin often gets a headache dealing with this person who is always wandering around with a scalpel. And so, someone who should never have appeared in the original story officially enters this world. She witnesses Shinichi Kudo take APTX 4869 and become Conan Edogawa, gradually gets to know Shiho Miyano, and keeps switching between the Black Organization and Conan's side. She takes part in cases that were already familiar to her, and her presence gives new endings to many tragedies that once seemed impossible to change. Gin: "Merlot, you'd better behave yourself." Vodka: "Big Brother, I think she's going to stab me with a knife again..." Ai Haibara: "How many more things are you hiding from me?" Conan: "Why is she at every crime scene?" Amamiya Yumi: "Don't ask. I just happened to be passing by." And it all begins on the day Shinichi Kudo becomes Conan Edogawa...
