Tazuru Kazami is someone the world calls a "Murdist," a murderer whose victims can only be described as works of art. The end to her 89-body killing spree only came after she surrendered herself to the authorities. However, her legacy lives on through numerous copycats who emulate her deeds in desire of fame, bathing Japan in blood. Shrouded in mystery, she offers information on these criminals, but only to one person: Yuki Otohito, a seemingly average college student. As the crime rate skyrockets with more and more copycats, Yuki is thrust into Kazami's mind games. Even though he never asked to take part in this, Yuki will do whatever it takes to catch those who take lives, all the while hoping to find clues behind his sister's disappearance.
