The once wealthy and powerful Ryuuzen clan has been all but destroyed. Their misfortune began in 1960, when a majority of the family was wiped out when their vacation villa was buried under a landslide. However, search and rescue teams discovered something even more shocking: A majority of the bodies they discovered showed obvious signs of having been mu*dered before the landslide.... more>>

As though it were a trigger, what came to be known as "The Curse of the Ryuuzen Clan" spread throughout the descendants of the family's only survivor. By mu*der, by su*cide, by accident... it seemed none who held the name "Ryuuzen" could live to see the age of 35, and now, the family has been reduced to a single woman, lying in a hospital bed, days away from death.

Kamo Touma was once just another of the endless parade of sleazy tabloid journalists looking to exploit a prominent family's tragedy to sell magazines, but Ryuuzen Rena's kindness melted his frozen heart, driving him to quit his old job and become an investigative journalist specializing in overturning cases of false arrest. Eventually, he and Rena were married, but now, the curse threatens to steal away their happiness.

Kamo prays for a miracle, and his prayers are answered by the Hourglass of Miracles, an artifact spoken of in rumors and urban legends, said to grant one wish to anyone who obtains it.

"Meister Hora", a guide for those who obtain the hourglass, tells Kamo there is only one way to break the curse and save Rena: He must travel back in time to the year 1960 and catch the culprit of the original Ryuuzen Family massacre.

Who was the culprit of the mu*ders that took place almost 60 years ago? Why did they steal away the lives of the Ryuuzen clan? What is the true nature of the "Curse of the Ryuuzen Clan?" And perhaps most mysteriously of all... What is Meister Hora's goal in all this?

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.

The protagonist, Kasumi Kuzushiro, is an introverted, somewhat cynical high school student who loves mysteries. Kasumi often finds himself dragged along on bizarre journeys by his flighty childhood friend, Yozuki Asahina. Due to their staggeringly bad luck, these trips often leave them in the wrong place at the wrong time to be caught up in locked room mysteries. 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?

It's simple.

She's...
