The Two Prisons

The Two Prisons (双子の牢, Futago no rō, lit. "Twin Prisons") are two identical buildings the eccentric architect Jarr Jorr built in England and Japan one hundred years ago.
==Overview==
The architect Jarr Jorr was part of a religious organization whose goal is to connect and communicate with outer space. It is said that he designed and built the Two Prisons for this purpose.
===Structure===
The Two Prisons are small identical buildings made of English brick. They have 3-cm-thick (1.5 inches) iron doors with an original design; the door frame is made of iron too. There is only a single room with a fireplace and a narrow chimney. The room's floor is a single slab of undressed concrete, and the brick walls have three layers—two veterans and one apprentice. Both prisons also have only one fixed window. The window's glass was specifically made and is, thus, one-of-a-kind.
The prisons' only differences are the emblem over their doors and the pattern on their window's glass. The Moon Prison has a crescent moon over its door and on its window's glass.
Furthermore, the prisons have identically shaped keys. Only their bows differ: One bears a crescent moon, the other a sun. The Moon Prison key was irreparably damaged in a house fire seven years ago, shortly after Juntaro Mihane was reported missing.
==Sun Prison==
The Sun Prison (太陽の牢, Taiyō no rō) is the prison in England. It is located near London.
70 years ago, a locked-room murder occurred at the Sun Prison: A man was tied to a chair and stabbed to death. Scotland Yard investigated the case, but were unable to solve it. Because of a bar that locked the door from within, the police could not enter that way and, thus, had to destroy the one-of-a-kind window to gain entrance. At some point, Fin Fennic, the world's expert on locked room studies, looked into the case and could not solve the mystery.
The Sun Prison's current owner is alive and sent Kiyotaka Mihane, the son of the Moon Prison's late owner, the Sun Prison's key to unlock the Moon Prison.
==Moon Prison==
The Moon Prison (月の牢, Tsuki no rō) is the prison in the Okutama Mountains, Japan. Close to the Moon Prison, the Moon Lodge is located.
Seven years ago, Juntaro Mihane purchased the Moon Prison with his inheritance. He was a member of the same religious organization to which Jarr Jorr had belonged and shut himself in the prison "to connect with space." Not long afterward, Juntaro was killed with a hit on the head. His family filed a missing person report, but he was not found and eventually declared dead. His corpse was found seven years later in the Moon Prison by his family.
Two weeks before the corpse's discovery Juntaro's wife Youko Mihane, his son Kiyotaka, his brother Junji Kaji, and his servant Kaki Sakanoue went to the Moon Prison because they wanted to liquidate Juntaro's estate. Because the door was locked and they did not want to damage the prison's sole and unique window, Kiyotaka contacted the Sun Prison's owner and asked them if he could borrow the Sun Prison key to unlock the Moon Prison. The Sun Prison's owner agreed, and the key arrived two weeks later. Juntaro's family opened the Moon Prison and found his corpse lying inside. Curiously, when they were there weeks earlier, they had not seen Juntaro's corpse through the window.
==History==
After Juntaro Mihane's family found his corpse in the Moon Prison seven years after his disappearance and death, they contact the Metropolitan Police Department. Amamiya and her team are called to investigate the case. Ron, who has learned about the case through one of Chicory's articles, and Totomaru also head to the Moon Prison to look into Juntaro's strange death.
There, Ron and Toto inspect the building with Amamiya and another officer when Fin Fennic and Shachi from BLUE arrive to take charge of the crime scene.
Fin goes to examine the prison with her Phoenix touch and notes that neither the door nor the walls surrounding it were tampered with and that the ceiling has no cracks or hollows. There is also no sign that the Moon Prison was restored since its creation. After inspecting the fireplace and finding foamed styrol mixed with the ash, she solves the mystery. Not long afterward, another corpse is found in the Moon Prison: This time, the victim was killed in the same manner as the victim in the Sun Prison Murder Case. The prison was modified like the Sun Prison had been back then too: A brass bar was mounted on the inside of the door to keep it locked.
Because of that, the door could not be opened and the window had to be destroyed. Nothing else was altered inside the prison.
==Trivia==
*It was initially said that the Sun Prison Murder Case happened ten, not seventy years ago.
