Lee and Sen, 149 Years Apart

In October 2026, 19-year-old Lee Turner arrives in Chiran, Japan, with his father, Jim Turner, an East Asian Studies professor specializing in Japanese history. They move into a secluded 200-year-old samurai house hidden behind thick sword ferns, but Lee is in no condition to appreciate his new surroundings.

His memories are badly fractured, and he relies heavily on Ativan, Benadryl, Xanax, and other sedatives to quiet his mind. He has lost his sense of smell, sees strange distortions in the world around him, and is haunted by what he thinks happened at NYU. Lee remembers attacking his roommate, whom he calls James Baldridge, and believes he may have killed him and concealed the body.

Even worse is the voice of Lee’s mother, who disappeared seven years earlier during a family trip to Cambodia. He hears her calling to him from inside suitcases, begging him to let her out.

The house itself gives Lee more reasons to question his sanity. There is an old bloodstain high on a kitchen doorframe, and a dead raccoon lies decomposing at the bottom of the property’s well. Jim’s Japanese girlfriend, Hina, spends time at the house cooking for them and tells Lee the story of Okiku, the murdered servant girl whose ghost supposedly haunts a well.

Nearly 150 years earlier, in October 1877, 16-year-old Iwasaki Sen is living in that exact same house.

Her father, Iwasaki Itaro, survived the failed Satsuma Rebellion and remains fanatically devoted to the samurai way of life. While hiding from imperial forces, he trains Sen to become a warrior, forcing her to spar with him and memorize teachings from the Hagakure, especially its insistence that the way of the samurai is found in death.

The rest of the family—including Sen’s mother, her 13-year-old brother Seijiro, and two-year-old Kotaro—lives in fear of Itaro. Their maid, Youna, provides one of the few gentle presences in the household. Food is scarce, yet Itaro clings to his pride and fantasies of restoring the samurai order. Sen has already seen what his obsession can cost: her younger sister Kura starved to death during a famine after Itaro withheld food from her.

The Door Between Their Worlds

Determined to clear his mind, Lee finally flushes his sedatives down the toilet. Soon afterward, he notices yellow light shining through the paper closet door in his bedroom—even though there is nothing behind it but a solid cement wall.

In 1877, Sen sees something equally impossible: a shadow moving behind her own closet door.

Lee writes a message backward in Japanese on the paper: “How did you die?”

Sen answers: “I will tell you tonight.”

When the door finally opens, Lee and Sen find themselves staring at each other. Sen immediately draws her katana, believing Lee may be a demon or spirit, but it becomes clear that both of them are physically real. Gradually, they understand the impossible situation: they occupy the same bedroom in the same house, but 149 years apart.

Lee proves that he knows Sen’s future by warning her that a fire will break out in Chiran the next day and kill the mayor. When it happens exactly as he predicted, Sen can no longer dismiss his claims.

Her own world, meanwhile, is becoming increasingly dangerous. Hunger and paranoia are pushing Itaro further into madness. During an argument over food, he orders Sen to punish her mother by cutting off two of her fingers with a dagger. Sen obeys. Her mother’s blood splashes high onto the kitchen doorframe, creating the stain that will still be there when Lee moves into the house in 2026.

Lee is uncovering disturbing secrets of his own. After breaking into Jim’s locked study, he discovers newspaper clippings about a dismantled human-trafficking and black-market organ ring in Japan. He concludes that his father brought him to Japan because Jim believes Lee’s missing mother may somehow have ended up there—or that pieces of her body might be found.

Sen Discovers When She Dies

As Lee and Sen become more comfortable with each other, the portal allows Sen to enter modern Chiran. Her arrival immediately creates practical problems: Hina has to stop her from walking outside carrying a katana because swords are illegal in modern Japan.

The modern world also destroys everything Sen has been taught to believe. She learns that the samurai class did not rise again after the Satsuma Rebellion. Her father’s dream of another rebellion is futile.

Then Lee takes her to the town hall.

Using Sen’s antique wooden identity passport, they locate her family in the official koseki registry. The record reveals something far worse than the end of the samurai.

Sen, her parents, and her siblings are all recorded as dying on October 27, 1877.

That date is only three days away.

Outside the archive, Lee grabs Sen’s arm, and modern Chiran suddenly seems to disappear. For a moment, they stand on white sand beneath a black sky as an enormous wave rushes toward them. Then the vision vanishes.

Lee becomes determined to change Sen’s fate. He begs her to convince her family to leave Chiran, but Itaro refuses. To him, fleeing death would be shameful.

When an imperial spy is discovered near the house, Itaro captures him and orders Sen to execute him. She decapitates the man on the back porch. Unknown to her, Lee is hiding beneath the porch in his own time, and the dead man’s blood drips through the floorboards onto him.

Their Worlds Begin to Collapse

Lee soon notices one of Sen’s watercolor paintings and is stunned by what he sees.

She has painted Lee’s mother, standing on a shore while the ocean closes around her.

When Lee and Sen hold hands and cross the closet threshold together, they enter an eerie shared space: a white beach beneath a dark sky. An empty, unzipped suitcase sits on the sand. As the suitcase begins filling with white sand, Lee and Sen themselves start turning to ash. They barely escape back into their own worlds.

Lee begins tracking when the closet opens and finally recognizes the pattern. The connection appears only during low tide.

In 1877, Itaro buys Sen a magnificent new katana and declares her the true “soul of the samurai.” But his grand gesture comes just as imperial troops close in on Chiran.

Knowing capture is imminent, Itaro decides his family must die rather than fall into enemy hands. He murders his wife and young sons while they sleep, then prepares to commit seppuku. He orders Sen to serve as his kaishakunin and complete his ritual death.

For the first time, Sen fully rejects him.

She realizes that the man who taught her to worship honor and death has used those ideas to justify cruelty, starvation, mutilation, and murder. She refuses to help him die and tells him, “I’ve chosen myself, and you are not my father.”

Enraged, Itaro attacks her just as imperial soldiers storm the property. Gunfire tears through the house, and Sen flees beneath the porch.

Lee Finally Remembers What Happened

In 2026, Lee’s own version of reality is collapsing.

His memories of NYU finally become clear. He did not murder his roommate. The young man was actually named Matt, not James Baldridge, and although Lee attacked him during a drug-fogged episode in a stairwell, Matt survived.

The name James belongs to someone else.

James is Lee’s father.

That realization unlocks the memory Lee has spent seven years suppressing. When Lee was twelve, he witnessed Jim murder Lee’s mother during their trip to Cambodia. Jim stuffed her body into a suitcase and buried her.

That is why Lee hears his mother calling from suitcases. That is the truth his mind has been trying to keep buried.

After Lee began remembering what happened, Jim realized his son might expose him and called the police to have Lee institutionalized. Father and son fought in the kitchen. Lee stabbed Jim to death with a kitchen knife, dragged his body outside, and dumped him into the well.

The corpse in the well is not simply another grotesque feature of the strange house. Lee has been living beside the place where he disposed of his father.

Otohime and the Truth About the House

As police close in on the house in 2026 and imperial soldiers attack it in 1877, the final supernatural mystery is revealed.

Hina and Youna are the same being.

She is Otohime, the immortal sea princess and daughter of the Dragon God from the legend of Urashima Tarō.

Long before the events in the house, Otohime encountered Sen when Sen’s mother tried to sacrifice her to the ocean. Otohime became attached to the lonely girl and eventually used her divine power to protect her from the death awaiting her in 1877. She created a pocket world around the house, holding Sen and her family inside an unnatural extension of time.

Generations later, Otohime encountered Lee after the murder of his mother. Lee, too, was heading toward death, this time through drugs and a fall during his breakdown. Otohime created another protected reality for him in 2026.

The two worlds were never supposed to meet.

But Otohime is a creature of the sea, and her power weakens when the ocean retreats. At low tide, the barriers surrounding her pocket worlds become thin enough for 1877 and 2026 to bleed together. That is why Lee and Sen can see each other through the closet—and why their connection disappears when the tide changes.

Otohime has not truly erased either of their deaths. She has only delayed them.

Lee and Sen Open the Box

Bleeding and trying to escape the police, Lee crawls beneath the porch in 2026. In 1877, Sen is hiding beneath that same porch while her home burns and imperial soldiers close in.

Separated by 149 years but occupying the same physical space, they begin digging into the earth.

Their hands uncover a small jeweled box decorated with turtles: Otohime’s tamatebako, the magical box from the legend of Urashima Tarō.

They understand that opening it will end the worlds Otohime created for them.

Together, Lee and Sen open the box.

All the time Otohime has borrowed and trapped is released at once. The artificial realities surrounding the house collapse, and neither Lee nor Sen can remain protected from the fate that has been waiting for them.

In 2026, Lee finally stops running from his memories. He accepts that his mother was murdered by his father, that he killed Jim, and that the horrors haunting him were distorted pieces of truths he could not face. Bleeding beneath the house, he finally becomes peaceful and dies.

In 1877, Sen also accepts death—but on her own terms rather than her father’s. She has rejected Itaro’s belief that dying obediently for the samurai cause is the only honorable way to live. As the pocket world disappears, Sen and Lee die holding hands across 149 years of time.

The novel closes with “The Last Letter of Iwasaki Sen,” a letter Sen wrote before the final attack and hid in Lee’s drawer.

Sen tells Lee that meeting him changed the way she thinks about endings. She no longer fears death because she believes time may be a circle rather than a straight line. If that is true, their deaths do not have to be the end of their connection. Somewhere, in another time or another life, perhaps they will find each other again.

She signs the letter with the identity she has finally chosen for herself:

“Iwasaki Sen, The Last Samurai.”
