管乃 雪

Age: 11 (at the time of her death)

One of the three main ghosts who roam Heavenly Host and the third victim of the murder case that took place in it. Her death was caused by repeated stabs in the left eye with a pair of scissors, reducing it to mush, and the subsequent removal of her tongue. She usually kills her victims in the same way she was killed, sometimes even playing with them and locking them in rooms where she can kill them without being disturbed. 

When the player appeases Sachiko's spirit and allows her to pass on, the school selects Yuki as the new 'Sachiko' of the school, as shown by her dress turning red. This can also be seen in two of the game's Wrong Ends as well./
