Is Kindaichi Case File Based On True Stories?

I am a doctor. One day, I come across a weird patient when I am on duty. The first thing she says when she sees me isn't that she feels unwell somewhere. Instead, she says something hair-raising. "Dr. Cantrell, your girlfriend is a murderer." "What nonsense are you spouting?" I shoot back with widened eyes and shoot up from my chair. I feel offended. She calmly says, "She won't be home tonight because she needs to deal with the body. You will know whether what I say is true by tonight."

A serial killer targeted me. My sister-in-law was assaulted and murdered while trying to save me. Not only did I refuse to call the police, I pushed my father-in-law and mother-in-law down a flight of stairs when they came to help. I even helped the killer destroy the evidence. When my husband learned that his entire family got killed, he broke down in tears. He grabbed me by the collar and demanded, "Why? Why would you do this?" I deliberately waved photographs of his family's gruesome deaths in front of him and burst into laughter. "Why?" I sneered. "Because they deserved it." My parents begged me to cooperate so I wouldn't be sentenced to death. Instead, I publicly severed all ties with them. Meanwhile, the murderer who escaped justice struck again, claiming another victim. As public outrage reached its peak, I was selected for the Memory Extraction Program. Before the sentence was carried out, my husband asked me one final time, "The Memory Extraction System is still a prototype. You could die during the procedure. "Tell us the truth now, and there's still a chance to make things right." I slowly raised my head to look at him. "You're not getting a single word out of me." The crowd instantly erupted. People shouted that a worthless life like mine deserved to die. But when my memories were finally extracted, they were the ones crying and begging someone to save me.

As the news broadcast reported a random serial killing near my residential complex, I knew—I had been reborn once again. In my first life, my husband insisted on going out in the middle of a snowstorm to buy weapons for self-defense. I locked every door and window, waiting at home, anxiety clawing at my chest. I never imagined the killer could pick locks. Before I could even react, a blade plunged into me, and I died on the couch. In my second life, I didn't hesitate. I hid in a concealed storage room, holding my breath. But the door was still pulled open. A man wearing a rabbit mask stared straight at me. "Found you," he said. In my third life, I ran to the police station. I rushed inside and told the officer on duty that the killings weren't random—that the murderer was coming for me. They looked at me like I'd lost my mind. Then my husband arrived in a hurry and took me away. But the moment we reached our front door, a heavy hammer smashed into the back of my head. Through the blinding pain, I forced my eyes open, but I never saw who killed me. Now, staring at the grave expression on the news anchor's face, agony surged through every inch of my body. Rebirth isn't a reset. The damage accumulates—and sooner or later, it will torture me to death. Without hesitation, I walked into the kitchen and set a pot of oil to heat. And I waited… for the moment the lock began to turn.

In the late stages of her pregnancy, my wife slipped away into the mountains with her childhood sweetheart, seeking some reckless thrill under the open sky. Fate, however, had other plans. She suffered a massive hemorrhage, and the two were rushed to the hospital. As a doctor, I took one glance at her condition and instructed the nurse to prepare for the cremation. In my previous life, I had risked everything to save her. On that very operating table, she and the child inside her perished together. Her childhood sweetheart, overcome with grief and fury, rallied others to accuse me of seeking personal revenge. Their rage was relentless, and they broke my hands. "A butcher like you, without medical ethics, deserves nothing less than eternal damnation!" they shouted, their words burning like brands on my soul. Yet I distinctly remembered—the surgery had been a success. Her vital signs had stabilized. Clinging to hope, I begged my in-laws to conduct an autopsy, to uncover the truth buried beneath the accusations. Instead, they called the police, who swiftly charged me with performing surgery under the influence of alcohol. Stripped of my rights, I was thrown into prison, where suffering became my only companion. Years later, upon release, I stumbled across a sight that tore what was left of my heart to shreds—my wife, alive and well, behind the wheel of a luxury car, accompanied by her childhood sweetheart and their child, living off the fortune I had worked tirelessly to build. Their betrayal didn't end there. Coldly and methodically, they lured me into a trap, casting me into a cement mixer to erase every trace of my existence. When I next opened my eyes, time had rewound itself. I was back on that fateful day, the one when her hemorrhage began.
