While wearing these glasses, Shiki cannot see the lines, and can thus live life as normal. Soon after discovering this power, he is given a special pair of glasses by a mysterious woman.
As a result of this injury, Shiki became able to see 'death lines' on objects and people if Shiki traces these lines with a sharp object, the person or object that they belong to will die or be destroyed. As a young boy, Shiki suffered a life-threatening injury. Tsukihime chronicles the story and life of a teenage boy named Shiki Tohno.
