Heiji Hattori and Kazuha Toyama

Background

Heiji and Kazuha have been friends since they were little kids, and have remained close throughout the years like Shinichi and Ran. They are a high school detective and a detective's daughter, which is also like Shinichi and Ran. They always bicker and make fun of each other, but they do have a soft spot for each other like best friends should. They also show hints of romantic feelings in the series, and everyone calls them a couple including their parents, Ran, Shinichi and others who see them together. However, they deny that they have any romantic interest in each other. They have gone together almost everywhere in the series and have gotten into danger together like when they were kidnapped. Heiji clearly shows that he is very protective of Kazuha from other guys (much like Shinichi is with Ran) but he only thinks of it as protecting his friend. Kazuha says she is like his much more mature and wise older sister. The truth is that in the 7th movie of the series, heiji discovers that his first love was kazuha in fact when he saw her she was looking for him but couldn't, so she decided to play with a ball and sing the song she was taught while cherry blossoms fell from the trees. Even this is the stupidest thing ever that a boy can do it's not as bad as heiji has it he says he doesn't know why he gets angrey when she is with other guys and how irritated when that happens, as anyone like shinichi says that he is being jealous of the fact that she is with another guy and not with him or is getting to friendly with the other person like when she was hugging by the arm a magican in a case. One Fact does stand though, they are always with each other till the end and will protect each other with there lives if calls for it.
