Tokyo, 1989

It was a rainy night, the dim street lights shimmering between the scattered puddles on the sidewalks. In one of the old neighborhoods of Tokyo, the small café "Yukimura" attracted its regular customers. The place was warm and cozy, filled with the quiet buzz of conversations and the aroma of fresh coffee.

In a corner sat a young man, lost in thought, watching the passersby through the window with a sly look. Izumi Kai, a thirty-year-old man, was tall and slender with sharp features and a cold gaze. He didn't talk much, but when he did, his words cut like a knife.

Izumi (muttering to himself): "This city is full of masks, no one shows their true face."

He worked as a private investigator, a job that suited his indifferent and aggressive nature. That night, he was waiting for a new client, unaware that this case would change his life entirely.

A Mysterious Encounter

A woman in her late thirties entered the café, carrying a wet umbrella. Yamada Natsu, dressed in a gray coat, let her black hair fall over her shoulders. She walked towards Izumi and sat in front of him uninvited.

Yamada: "Mr. Izumi Kai, right?"

Izumi (coldly): "Yes, what do you have?"

She handed him a brown envelope. He opened it with hands that didn't tremble for a moment. It contained photos of a young woman and some documents.

Yamada: "This is my daughter, Haruna. She disappeared two weeks ago. I want you to find her."

Izumi's face showed no expression. He flipped through the photos one by one. Haruna seemed like a happy girl, but there was something in her eyes.

Izumi: "Did you report to the police?"

Yamada (with restrained anger): "Yes, but they did nothing. I need someone who will go beyond official investigations."

Izumi nodded, took the envelope, and placed it in his bag. He stood up, and before leaving, he looked at Yamada and said:

Izumi: "I will find her, but don't expect to get the same person back."

The Beginning

The next night, Izumi began his investigation. He went to the small apartment where Haruna had lived. The place was neatly organized, but something felt off in the air. He searched the rooms, opened drawers and closets, and found Haruna's diaries. They were filled with drawings, scribbles, and disjointed words.

Izumi (thinking): "She was suffering from something, but what?"

As he flipped through the diaries, he found an old group photo. He recognized one face in it, his old friend "Oyama Ken," a man he wished he could forget.

Izumi (in a low voice): "Ken...

Memories rushed back forcefully. Ken had been his partner in petty crimes in the past, before they went their separate ways. He had a bad influence on everyone around him, and Izumi knew that well.

Izumi decided to visit Ken in his old apartment, hoping he might have some answers. But he knew this visit would open long-closed doors to his dark past.

Meeting the Past

Izumi stood in front of Ken's apartment door, hesitating for a moment before knocking. Ken opened the door, looking surprised.

Ken: "Izumi? What are you doing here?"

Izumi (coldly): "We need to talk."

Izumi entered the apartment, closing the door behind him. The place was filled with random items, just as he remembered it.

Ken: "What's up? I haven't seen you in years."

Izumi: "Haruna. You know her, don't you?"

Ken's expression changed, showing signs of tension.

Ken (nervously): "Why are you asking about her?"

Izumi (in a threatening tone): "She's missing. And I think you know something about it."

Ken seemed conflicted, as if there was an internal struggle.

Ken: "Izumi, I didn't want to get involved in this... It's a dangerous matter."

Izumi (insistently): "What do you know?"

Izumi approached Ken with steady steps, forcing him to confess.

Ken (in a low voice): "She was looking for her biological father. She discovered things she shouldn't have."

Izumi looked sharply at Ken, with many questions running through his mind.

Izumi: "And where is she now?"

Ken: "I don't know, but she was talking about meeting someone in Nagoya. Maybe you'll find answers there."

Izumi nodded and left the apartment, leaving Ken behind. He now had a single lead pointing to Nagoya, where the truth awaited him.

Izumi began his journey to Nagoya, knowing that this trip would reveal more secrets than he had anticipated.

Journey to Nagoya

Izumi took the bullet train to Nagoya. Thoughts swirled in his mind as he looked out the window at the rapidly changing scenery. He felt that something big awaited him at the end of this journey, something that could change the course of his life.

Encounter with the Truth

He arrived in Nagoya in the evening and headed to a small hotel, renting a room. Sitting on the bed, he took out Haruna's diaries and the group photo. He had to start over, but this time in a city where he knew no one.

New Investigations

Izumi began visiting places that might be connected to Haruna. He went to universities, libraries, and cafés she might have visited. He spoke to students and employees, but got no useful information.

One day, while wandering through an old district of Nagoya, he came across a small bookstore called "Tatara." He decided to enter, hoping it might contain something useful.

Tatara Bookstore

He entered the small bookstore, greeted by the antique smell of books. As he wandered between the crowded shelves, he noticed an elderly woman sitting behind the reception desk. He approached her and introduced himself.

Izumi: "Good evening. My name is Izumi Kai. I'm looking for a girl named Haruna. She might have visited this bookstore."

The elderly woman looked at him with sharp eyes, then nodded.

Elderly Woman: "Yes, I remember her. She used to come here often, looking through books on history and genealogy."

Izumi was surprised by this new information and asked hesitantly.

Izumi: "Do you know what exactly she was looking for?"

Elderly Woman: "She was interested in her family. She asked about old family names in Nagoya, as if trying to connect the dots."

Izumi realized that there was something bigger behind Haruna's disappearance, perhaps related to her family's roots. He thanked the woman and left the bookstore, carrying more questions with him.

Visit to the Archives

Izumi decided to visit the central archives in Nagoya, where he could access records of old families. After a long day of searching, he found records related to the Yamada family, discovering that Haruna's biological father was a man named Matsuda Koji, a mysterious figure linked to old crimes and dark secrets.

Izumi began piecing things together and found out that Matsuda Koji was connected to an old criminal network. Haruna was about to uncover the truth about her biological father, and this might have led to her disappearance.

Unexpected Meeting

As Izumi was leaving the archives, he sensed a shadow moving behind him. He turned quickly to find a tall man with harsh features standing in the corner. Izumi recognized this man, it was Murakami Hiro, a member of the criminal network that Matsuda Koji was part of.

Murakami (with a sarcastic smile): "You're looking for Haruna, aren't you?"

Izumi (seriously): "What do you know about her?"

Murakami: "I know a lot. But you won't be happy with what you discover."

Murakami approached Izumi slowly, his eyes filled with challenge.

Murakami: "If you want the truth, come with me. But remember, some doors should stay closed."

Izumi hesitated for a moment, but he knew this was his only chance to find the truth. He followed Murakami to a dark alley, where a black car awaited them. Izumi got into the car, knowing that what he would discover might be more than he could handle.

Secrets Revealed

Murakami drove to an old house in the outskirts of Nagoya. They entered the house and headed to a dark basement. In this basement awaited a collection of documents and photos revealing a long history of crimes and family secrets.

Murakami: "This is the truth you've been searching for. Haruna's father was involved in things he shouldn't have been. And Haruna discovered this truth, which put her in danger."

Izumi began reading the documents, each page revealing a new dark side of Matsuda Koji's life and his connections to the criminal network. Izumi realized that Haruna might have been a victim of a conflict she knew nothing about.

Izumi (in a low voice): "Where is she now?"

Murakami: "I don't know. But she was talking about meeting someone important before she disappeared. Someone who might be the key to all these mysteries."

The pieces of the puzzle began to come together in Izumi's mind. He had to find this person, knowing that time was running out. He decided to return to Tokyo, where he might find more answers. The journey was far from over; it had just begun.

On the way back to Tokyo, Izumi felt the weight of responsibility. He had to save Haruna, but more importantly, he had to confront the shadows of his past that he had always tried to escape.

This was just the beginning of a long and dark journey, a journey toward truth and justice, a journey that might cost him everything.

Return to Tokyo

Izumi returned to Tokyo, burdened with questions and information he had gathered from Nagoya. Now he had to continue the search in the capital, where the threads of the story intersected in a complex manner. After arriving at his small apartment, he sat at the table and took out the documents and photos he had collected. He needed to plan his next move carefully.

Visit to the Past

Izumi decided to visit his old friend "Fujikawa Hitoshi," who worked as a detective in the police force. He knew that Fujikawa might be able to help him get more information about Matsuda Koji and the criminal network.

Izumi arrived at Fujikawa's office at the police station. Fujikawa greeted him with a tired but sincere smile.

Fujikawa: "Izumi, I haven't seen you in a while. What brings you here?"

Izumi: "I need your help. I'm looking for a girl named Haruna, and I believe her disappearance is linked to an old criminal network. I found out about her biological father, Matsuda Koji."

Fujikawa's expression changed upon hearing the name.

Fujikawa: "Matsuda Koji? I haven't heard that name in years. He was involved in many crimes but disappeared before we could arrest him."

Izumi took out the documents and photos and placed them on Fujikawa's desk. As Fujikawa went through them, his tension grew.

Fujikawa: "If this information is correct, we're dealing with something very dangerous. I'll need some time to investigate this, but you need to be careful."

New Leads

While waiting for the results of Fujikawa's investigations, Izumi decided to visit Haruna's apartment again. He felt that there was something he had missed the previous time. He entered the apartment and began searching again, this time more meticulously.

In one corner, he found a small box hidden under the bed. He opened the box and found a collection of letters and diaries inside. These letters were addressed to Haruna from someone named "Miura Shinji," containing details about their meetings and future plans.

Meeting Shinji

Izumi decided to search for Miura Shinji. After a long search, he discovered that Shinji worked as a psychiatrist in a small clinic in Shinjuku. He went to the clinic and waited until the end of work hours.

When Shinji came out, Izumi approached him.

Izumi: "Miura Shinji? My name is Izumi Kai. I'm looking for Haruna."

Shinji was surprised, showing signs of worry.

Shinji: "I haven't heard from her in a while. Why are you asking about her?"

Izumi: "You have information that might help me find her. I discovered that she was looking for her biological father and that there are dangerous matters related to this issue."

Shinji hesitated, but after seeing the seriousness in Izumi's eyes, he decided to talk.

Shinji: "Haruna was suffering from psychological disturbances due to discovering the truth about her father. I was trying to help her deal with this situation, but she suddenly disappeared."

Secrets Revealed

Shinji gave Izumi the address of an old house in the outskirts of Tokyo, where Haruna was planning to meet someone important. Izumi thanked Shinji and decided to visit this place.

Upon arriving at the old house, the atmosphere was eerily quiet. Izumi entered cautiously, feeling that something was not right. While inspecting the rooms, he heard a voice behind him.

Mysterious Voice: "I knew you would come."

Izumi quickly turned around to find an old man standing in the corner, holding a knife. This man was Matsuda Koji, Haruna's biological father.

Matsuda (with a cold smile): "My daughter was about to uncover things she shouldn't have known. And I won't allow that."

The confrontation between Izumi and Matsuda began, filled with tension and danger. This was a crucial moment in Izumi's journey, as he had to fight not only to save Haruna but also to save himself from the shadows of his past.

The Near End

After a long and bitter struggle, Izumi managed to subdue Matsuda and tie him up. He called Fujikawa and informed him of what had happened. The police arrived and arrested Matsuda, and investigations began to reveal more secrets.

But the most important question remained unanswered: Where is Haruna? Izumi had a feeling that she was still alive, and that there were more things to uncover before he could save her.

This was just the beginning of solving the complex mysteries surrounding Haruna's disappearance and the truth about her father. Despite the dark and dangerous road, Izumi was determined to continue the search until the end.

Open Ending

Izumi sat in his apartment, feeling the weight of responsibility on his shoulders. There were many questions still needing answers and many people he needed to face. But at that moment, he knew that his mission was not over yet.

He had to continue the search and find Haruna, no matter the cost. Because in the end, this search for the truth is what gave him the strength to face the darkness surrounding him.
