A childhood friend of Yuuki. Her ambition is to become a manga artist. She is very kind but is even scarier than Azumi when angry—usually with a smile that scares other characters (Yuuki once says that as a child, his worst fear was Haruka getting angry). In the anime, she is Panta's human partner and still has feelings for Yuuki . This causes Yuuki to break up with Katie for a while. When Haruka realizes that Dylan's true love is Katie, she finally gives up on him. At the end of the series she is dating Koichi Sumita. (First appearance: episode 154)
