Ninzaburo Shiratori
Another officer who works with Megure and likes Sato; however, she does not feel the same about him. He made his first appearance in the first Detective Conan movie and his manga appearance was in Volume 21, along with Officer Sato. Later in the series he makes overt advances towards Miwako, relying heavily on his status as the scion of a wealthy family (and doing his best to make the shy and awkward Takagi feel inferior in the process). Spoiler Actually the reason behind his liking towards Miwako is because he thought Miwako was his first love. But later on, he found out that his first love is in fact Kobayashi, Conan's teacher.
