Hi, let me introduce myself. My name is Shiho Miyano, I was born into the secret criminal syndicate “Black Organization”. While my British Mother—Elena Miyano and Japanese Father—Atsushi Miyano, I was both scientists working for the Black Organization to develop a mysterious drug called the “Silver Bullet”. While I was young, both my mother and father died in what the Black Organization claimed to be an accident.
Unlike my older sister—Akemi Miyano who lived a normal life in Japan, I was groomed by the Black Organization to take over my parents’ research by sending to the United States for education at a very young age. Upon returning to Japan and by reaching the age of 13, I started to work as a scientist for the Black Organization where I was given the alcoholic codename “Sherry”.
The Professor eventually adopts me and learns that I was a former Black Organization Member who created and developed APTX 4869, the drug which shrunk Shinichi into his child form. Although the Professor thought of telling Shinichi that he had found APTX 4869’s Creator, I'm insisted to the Professor to keep everything that happened as a secret as I wanted to tell Shinichi everything about my personally.
