There exist in this world a set of six daggers that carry a terrible curse: the ability to inflict a death beyond time.

This is the story of "Raine" and "Marie", two souls bound by the daggers' curse to kill one another, over and over again.... more>>

France, 1243. Lapis Lazuli Castle is the name of an insignificant relay fort nestled away in a forest east of Carcassonne. Its ruler, Count Geoffroy, and his only daughter, Marie, are both believed to be insane. The root cause of their shared madness is the mysterious disappearance of Geoffroy's wife three years ago, which caused Geoffroy to grow detached from humanity and cast Marie into a deep depression. After three years of wandering in a state halfway to nonexistence, Marie works up the nerve to ask her chief bodyguard, Sir Raine, to investigate her mother's death, confiding that on the night of her mother's disappearance, she had witnessed something impossible. However, her investigation only prompts a new tragedy.

The French-German border, 1916. As World War I rages on, Raine and Marie's latest reincarnations live the life of a sub-lieutenant in the French army and a medic with the Red Cross, respectively. The two lovers are reunited at the site of the Battle of Verdun, but no sooner have they met then Raine finds himself faced with a barrage of impossible circumstances. An enemy soldier's head suddenly vanishes, right before his eyes. One of his subordinates reports the same thing happening to an ally. Four more headless bodies vanish from a flooded bunker in the minute he looks away. These baffling events are a prelude to the return of their old tragedy.

Northern Hokkaido, 1989. Kimiyo, age eighteen, is already dying, an inoperable tumor in her hypothalamus leaving her with less than a year to live. Refusing to despair in the face of her tragic circumstances, she spends her remaining days with her friends at "The Library at the End of the World", a private library so called due to its isolated nature. One day, a man named Kito approaches her out of the blue, regaling her with a story about a set of cursed daggers, knights in the 13th century, and the two of them being cursed, fated lovers. Naturally, Kimiyo is intensely skeptical, but the events that come next don't require her to believe in them.

Arriving at the scene of these three tragedies is Snowy, an enigmatic figure of indeterminate gender who claims to be "a detective charged with managing the world's chaos". <<less

In the winter of three years ago, the first locked room mu*der in Japanese history was committed.... more>>

All of the evidence pointed to the defendant. It was certain they were guilty. And yet, they were found innocent and released. Why? Because the crime scene was a perfect locked room no one from the police or the prosecutor's office could solve.

"Since the room was locked, it was impossible for the defendant to have committed the mu*der. It's no different than if they had a perfect alibi." That was the argument of the defense, and that was the argument the judge sided with.

The ruling sent a ripple throughout Japanese society. No matter how suspicious you were or how much evidence you left behind, as long as you managed to create a locked room that no one could solve, you were immune from prosecution. With the common anti-mystery fiction talking point "there's no reason anyone would ever actually commit a locked room mu*der" completely overturned, the rate of locked room mu*ders in Japan skyrocketed.

When the police proved unable to deal with the surge of locked room crime, the Ministry of Justice published an official categorization of all known locked room tricks as an investigative aid. When that proved insufficient, Division Zero of the Tokyo Metropolitan Police Department, a police division dedicated solely to solving locked rooms, was created. When that still proved insufficient, locked room detectives, private investigators specializing in locked rooms, were officially licensed by the state and authorized to participate in police investigations. Calling a locked room appraiser, someone specializing in searching buildings for secret passages, is now a common first step in criminal investigations.

On the other side of the spectrum, locked room agents, assassins and crime planners specializing in locked room mu*ders, have become some of the most notorious criminals in Japanese history, and even a cult worshiping the scenes of locked rooms as a way to purify the souls of the deceased has made rapid inroads into Japan.

Fortunately, another of Kasumi's childhood friends, Shitsuri Mitsumura, is the greatest locked room expert in the world, and can always discover the truth.

Hm? How did a high school girl become the greatest locked room expert in the world?
