Demon City: The City’s Hidden Sins

A haunted city, deadly secrets, and a family’s revenge – this is the final story of the movie “Demon City”. Through the story of this movie, we are shown a dangerous and dark side of a small town called Shinjo City.

Today I am going to tell you about the story of this movie. How this town hid dark secrets, how a family was destroyed, and how a father came from behind to save his daughter.

Part One: The Dark Side of Shinjo City

Shinjo City started out as an ordinary, poor town. The mayor, Sunohara, changed the city. But behind that change was a very dangerous secret. The Yakuza gang called Kimen-gumi began to control the city. They started to make money by selling drugs and trafficking people. The police and politicians in that city were also in league with this gang.

Something incomprehensible happened in the city. Poor people started disappearing. People were dying. But no one talked about it. Why? Because the big men in the city suppressed all this. They wanted to build a casino called “Mahoroba” in Shinjo City. But what happened to those who opposed it? They disappeared.

Part Two: The Unfortunate Fate of the Sakata Family

Sakata is a human. He was an assassin in a yakuza gang. He had a wife and a daughter – their names are Ai and Ryo. Sakata wanted to leave the yakuza gang and live a normal life. But Sakata was not allowed to do so.

One day, a new yakuza gang called the Kimen-gumi came to his house. They killed Sakata’s wife. They took his daughter and threatened her. Sakata told them: “I will kill you all. Remember, one day I will kill you all!”

But they tried to shoot Sakata. They went to the media and said that Sakata killed his wife and daughter, and then he shot himself. But Sakata didn’t really die. He was in a coma for 12 years. Then he woke up.

Part Three: The Road to Revenge

Sakata woke up 12 years later. He was shot in the head, so he can’t speak. But there’s only one thing in his heart – revenge. During those 12 years, Shinjo City has changed a lot. People have forgotten about him. Some think he’s dead.

There’s a police officer named Takigawa. He remembers Sakata’s story. He helps Sakata find those secrets. They find that Sakata’s daughter, Ryo, is still alive. But she’s being held by the leader of the Kimen-gumi gang – the city’s mayor, Sunohara.

Sakata then begins his journey of revenge. He kills the people who destroyed his family one by one. But he does not know the real secret. Shinjo City is a ghost town. Every 50 years, a demon appears. That demon starts killing people. The mayor of the city, Sunohara, wants to catch that demon.

Part Four: The Secrets of the City

Sakata finally finds out where his daughter Ryo is. He goes to save his daughter. But there he has to face Sunohara. Sunohara is the leader of this gang.

Sunohara tells Sakata the main secret of Shinjo City. “There is a demon here. That demon appears every 50 years. You think you are an innocent man. But in fact, you are that demon. You are the one who killed your wife.”

A fight breaks out with Sakata. Seeing Ryo, Sakata remembers who he is. He saves his daughter. But in the fight, he is badly injured. He tells his daughter, “I couldn’t protect your mother. I’m sorry.” Sakata dies in his daughter’s arms.

In the end, Sunohara wins. He is victorious as always. He goes to the media and says that he killed Sakata and has saved the city again. The “Mahoroba” casino finally opens. The city becomes peaceful.

But Ryo knows the truth. She remembers that her father really did protect her. Since then, she has lived alone, the only one who knows that terrible secret.

Final Thoughts

Cities like Shinjo City are everywhere in the world. Sometimes, there is a dark side to any seemingly successful place. People are willing to sell even the best things for money and power. But there are some people who are willing to fight against that darkness. Like Sakata, there are some people who are willing to sacrifice their lives for the truth.

This film shows us that every person has a dark side. Sometimes that dark side can be closer than you think. It can be in your city, your neighborhood, or even inside yourself.

Like the people of Shinjo City, we too must choose how we live. Do we surrender to power and money? Or do we fight for truth and justice? That is the question that Demon City asks us.

This story touched my heart because it shows the corrupt nature of society. No matter how beautiful it may seem, cities like Demon City have many dark secrets. Those secrets will eventually come out, like a demon rising.
