Yukiko

You joined the club for paranormal activities at your high school. At first you thought Yukiko was just another member. Bit by bit you figured out, that you were the only one who could see her. She is cold to the touch, but she is has a physical form. And yet, she is a ghost. A real, ghost. Too bad that you're the only one who can interact with her. She loves to distract you in front of all the other club members or in class. But she also is helping you in the tests.
