This includes the death of inanimate objects as well as living beings and undead beings. Because of his Mystic Eyes of Death Perception making him see death lines Shiki has immense headaches as his mind cannot cope with the sight of death. Soon after he is given a pair of glasses from Aoko Aozaki that blocks the sight of these lines. The game then advances to Shiki's second year of high school. After his injury, he was banished to a branch family of the Tohno household. After eight years he is called back home by his younger sister, , when she assumed the responsibility as the family's head. After moving back Shiki has trouble adjusting to the old-fashioned lifestyle his sister lives by.
