Tsukihime

This story is about a boy named Tohno Shiki who, after a traumatic accident in the hospital, wakes up with the ability to see lines and cracks in every surface and being. When these lines are traced with a sharp or blunt edge, they are cut forever. Forced to see these lines everywhere, Shiki is distraught until he meets a magician girl who gives him glasses that allow him to live a normal life. Years later, after living in a relative's house, he is called back to the house he left years ago after his father dies. There he must learn to live with his younger sister and two maids. One day, Shiki's life is thrown off course when he meets a blonde woman on his way to school and feels the urge to kill her.
