Series Details

Series Explanation

The story begins in Germany, where Dr. Kenzo Tenma works as a brilliant brain surgeon at a prestigious hospital. He’s young, respected, and engaged to the hospital director’s daughter. His future seems perfect. But everything changes one night when two emergency patients are brought in—a famous politician and a young boy with a gunshot wound to the head. Tenma is told to operate on the politician. But he chooses to save the boy instead, believing that all lives are equal. The politician dies, and Tenma’s career falls apart.

The boy Tenma saved is named Johan. Not long after, strange things begin to happen. People around the hospital start dying. The boy and his twin sister disappear. Years pass, and Tenma becomes a respected doctor again. But his peaceful life is shattered when he comes face-to-face with Johan—now a grown man. Johan is charming, intelligent… and a monster. He’s behind murders and manipulation, leaving destruction wherever he goes.

Haunted by guilt, Tenma sets out to stop Johan. Not just to save others—but to undo the mistake he made by saving him in the first place. What follows is a long, intense journey across Germany and beyond. Tenma meets people from all walks of life—runaway children, grieving parents, detectives, and survivors of terrible pasts. Each one has been touched by Johan’s darkness in some way.

Johan doesn’t kill for revenge or power. He kills because he wants to understand what it means to be empty. His mystery goes deep into his past, back to a cruel orphanage, secret experiments, and forgotten truths about Eastern Europe. The more Tenma learns, the more terrifying it becomes.

But this isn’t just about Johan. It’s about Tenma, too. A man who tries to hold on to his beliefs, even when faced with evil. He refuses to become a killer, no matter how much he is pushed. Around him, other characters face their own moral choices. Inspector Lunge, obsessed with solving the case. Nina, Johan’s twin sister, who wants to face her past. Eva, Tenma’s ex-fiancée, caught between love and fear.

As the story unfolds, it raises painful questions. What makes someone a monster? Is it their past, their choices, or something they were born with? Can a person still hold on to their humanity when everything around them falls into darkness?

The ending doesn’t bring a loud answer. Instead, it leaves you with quiet chills and thoughts you can’t shake. The final moments are calm, almost soft—but underneath, they carry a heavy weight. Monster doesn’t scream. It whispers. And that’s what makes it so powerful.

My Honest Review

Monster is not easy to watch, but it’s unforgettable. It moves slowly, but every moment matters. The story builds pressure like a quiet storm. It’s filled with emotional pain, moral questions, and a quiet fear that something is always just around the corner. What I loved most was how real the characters felt. They weren’t just part of a mystery—they were people trying to survive, heal, and make sense of their lives. This series doesn’t hand you easy answers. It trusts you to think and feel deeply. And when it ends, you don’t just walk away—you carry it with you.

What the Series Teaches Us

Monster teaches us how fragile a person’s sense of right and wrong can be. It shows how one moment can change a life forever. Through Tenma, we see the pain of doing the right thing when it costs everything. Through Johan, we see what happens when someone loses all sense of meaning. It reminds us that true strength is not in violence, but in choosing not to lose your soul, even when surrounded by darkness. It also asks something powerful—can a person still believe in goodness when the world shows them nothing but pain?
