Appearance Yellow is a female, but a recurring humor in the manga is that she disguises herself as a boy so that most people don't notice. Her disguise is as simple as wearing a hat over her head to conceal her long blonde hair. Personality Like many other females, Yellow has many secrets from everyone including her friends. She is also very shy at first but once you get to know her she opens up more than most females do. Yellow has a good heart even if she does wear masculine clothes. She also loves animals especially cats. When she was younger, she wanted to be a cat when she grew up. History Yellow was born in a small town in Japan called Hokkaido. She has no idea who her parents are because they abandoned her when she was young. She lived alone until she was adopted by Tetsu and Mitsuo Yagami, two detectives who work for the police department. They live in an apartment building called "Yokosuka Heights" where there are many other adults who work at the police department. Yokosuka is a city on the opposite side of Japan from Tsutsujidai where the manga takes place. Tetsu and Mitsuo were only able to adopt her because they knew how poor her family was. Even though they tried their best to give her a normal life, she still longed for her real family.
