Monster

MONSTER

Everyone faces uncertainty at some point in their lives. Even a brilliant surgeon like Kenzo Tenma is no exception. But there’s no way he could have known that his decision to stop chasing professional success and instead concentrate on his oath to save peoples’ lives would result in the birth of an abomination. The questions of good and evil now take on a terrifyingly real dimension.

Years later, in Germany during the tumultuous post-reunification period, middle-aged childless couples are being killed one after another. The serial killer’s identity is known. The reasons why he kills are not. Dr. Tenma sets out on a journey to find the killer’s twin sister, who may hold some clues to solving the enigma of the “Monster.”

Johan Liebert
Johan Liebert

ヨハン・リーベルト

MAIN

Johan Liebert is the older twin son of the Lieberts, whose father Michael was an East German trade advisor who defected to the West. He is the titular "monster" and the main antagonist of the series. The mystery of his past is the focus of the plot. He is called a monster, the next Adolf Hitler and the devil himself. Johan was shot in the head as a child when his parents were killed in their home, but saved from death by [Dr. Tenma](https://anilist.co/character/718). Because of this, he regards Dr. Tenma almost as though he was his father. He claims to love his twin sister [Anna](https://anilist.co/character/720), and has some loyalty to her. Johan has spent parts of his life in different places under different names. He possesses charisma and intelligence but is also cunning, manipulative and deceitful; while he is seemingly kind, compassionate and loving to children, he is actually cold, cruel and fundamentally incapable of empathy. He uses his talents to manipulate and corrupt others, often with no apparent end than to cause suffering and destruction. His goal, as he stated when he was young, is to kill everyone that knows of his existence, and be the last one standing at the end of the world. He identifies with other killers, discovering their secrets. One of the themes of Monster is how individuals are capable of transforming into monsters; Johan often acts as both a direct and indirect catalyst for this transformation. ~! During his "perfect suicide" he was shot in the head by a bystander and seemingly died, but was later saved by Kenzo Tenma. !~

Kenzou Tenma

天馬賢三

MAIN

Doctor Kenzo Tenma is a Japanese neurosurgeon working at the Eisler Memorial Hospital in Düsseldorf. At the beginning of Monster he is favored by the department director for his prodigious surgical skill. After a crisis of conscience, he chooses to save the life of a young boy instead of the city's mayor, and is unjustly demoted as a result; he then becomes suspect for murder when the department director and several prominent doctors are killed weeks later. It is only after nine years that Dr. Tenma learns the perpetrator of the hospital murders is none other than the boy he saved years before, [Johan Liebert](https://anilist.co/character/719). Plagued by guilt, he resolves to find Johan and end the life of this "monster" he feels responsible for creating. Despite his mission, Dr. Tenma is a humanitarian who genuinely cares about the lives of others. These acts of kindness make him very influential with the people he meets.

MAIN

[Johan](https://anilist.co/character/719/Liebert-Johan)'s twin sister and the only unharmed survivor of the night when both her parents and her brother were shot in what appeared to be a botched burglary.

After she and her brother disappeared, she was adopted by the Fortner family from Heidelberg, who were unaware of her previous identity as Anna Liebert. As Nina Fortner, she was a hardworking law student at an unnamed university (likely the University of Heidelberg), as well as an adept practitioner of Aikido. She lived her life in peace until Johan made contact with her on her twentieth birthday. She comes to pursue Johan, albeit by different methods and for a different reason than [Tenma](https://anilist.co/character/718/Tenma-Kenzou).

Eva Heinemann

エヴァ・ハイネマン

MAIN

Eva Heinemann is [Doctor Tenma](https://anilist.co/character/718/Tenma-Kenzou)'s fiancée and the daughter of the Director of Eisler Memorial Hospital. She leaves Doctor Tenma after he is demoted by the Director for disobeying his orders. After Director Heinemann is murdered by [Johan](https://anilist.co/character/719/Liebert-Johan), she tries to return to Tenma, then recently promoted Chief of Surgery due to holes created in the staff by the murder. After being rejected by Doctor Tenma, she later becomes an extremely embittered alcoholic, a three time divorcee who uses the money from divorce settlements to finance her lavish lifestyle. After burning her house down in a drunken rage, she wanders throughout Germany and is also caught up in the investigation of the Monster. Although she does not personally suspect Dr. Tenma as having caused her father's death, one of the things she lives for is to see him suffer in prison in retribution for his rejection of her, as she had previously turned over evidence incriminating Dr. Tenma to [Inspector Runge](https://anilist.co/character/721/Runge-Heinrich). Her relationship with Tenma can be characterized as obsessive. During the series, she becomes a main target of [Roberto](https://anilist.co/character/8611/Roberto).
