One day, Prince Redmond—Lumiere’s fiancé, a duke’s daughter—suddenly became a yandere.... more>>

For a long time now, he’d tend to his business as a proper gentleman. Their relationship was more similar to that of business partners…

…However, that came to an end when he suddenly whispered sweet nothings to her.

“You only need to remain within my sight. Don’t you like it as well? Lumiere, you belong only to me.”

(Gross—!)

Nevertheless, he was His Highness the Crown Prince, a man with a promising future. Lumiere, who had no power to veto, took a desperate measure.

“Alright, I shall pretend to be the type of woman he loaths the most to incite his ire!”

Be it a white marriage or an annulment—she was prepared for them! She’d absolutely escape from that yandere!

…Even though she was willing to risk dying, for some reason, His Highness began to dote on her even more! Moreover, the other male aristocrats also transformed into yandere and surrounded Lumiere!?

If left as it is, the country might fall into ruin because of these yandere—!?

Hey, Silver, stop laughing and help me out!

He held absolute power, excluding his colleagues and taking credit for the research results of other researchers, which eventually led to a rebellious and despised situation.... more>>

He died in the winter of the Empire’s year 1202 at the age of 31. It was only after his death that people came to know about the various illnesses and suffering he endured throughout those years. He single-handedly withstood the pressure and defamation from the Senate and developed the S305 drug, capable of curing genetic diseases.

On the day of his burial, ten thousand people came to pay their respects, but he will never return.

The anti-fans who had criticized Ji Shiqing went back in time to 1201, just after Ji Shiqing had celebrated his 30th birthday. He had nothing left, but still faced the three-way pressure from the Senate, political enemies, and the public, and was determined to complete…

Now that everything has started over again, is there still a possibility to redeem everything? <<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.

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.

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...
