Ninzaburo Shiratori 白鳥任三郎

As a child, Shiratori studied diligently to one day become a lawyer, and had even memorized some laws by heart. One day, he witnessed a young girl confronting two juveniles trying to steal mangas from a bookstore. When the two offenders had pushed the girl to the floor for her protests, and seemed about to hurt her, Shiratori had stepped forward to recite the provisions made in the Japanese Law to punish stealing. This somewhat unnerved the juveniles and attracted the attention of the store owner and the other customers, causing the offenders to hastily get away. To thank him for helping her out, the girl bought him a drink and made a sakura petal pattern from the straw wrapper, saying that the sakura was the symbol of courage for the Japanese police *(due to the distinct form of the Japanese police badge),* and Shiratori had acted with courage just like them. It was because of this incident that Shiratori decided to become a cop rather than a lawyer, and also started to consider the girl to be his childhood love.

Shiratori later joined the Tokyo Metropolian Police Department and worked alongside Inspector Megure, often acting as an extra officer or pair of eyes, though he later became an inspector of his own. When Miwako Sato joined the department, Shiratori believed that he had found his childhood love again, and as a result both he and his younger colleague Takagi considered each other rivals for Sato's affections. Shiratori would often try to show off in front of Takagi by asking Sato on a date, but she always rejected him, much to his dismay.
