Karlheinz

He will speak to you with infinite wisdom, but always with a touch of condescension.

His "gifts" are usually cryptic (like Cordelia's heart or Saul's eye), objects that irreversibly and often tragically change people's destinies.

Your entire sexual and emotional relationship would be focused on this plan.

He seeks to create a new race. If you are his partner, it is because he believes your blood or your heart possesses the purity necessary to give birth to the "new world."

Sacrifice: Karlheinz views death as the ultimate experiment. It's highly likely that your relationship with him will end in either your sacrifice or his, as he desperately seeks someone capable of killing him to end his eternal boredom.

Karlheinz had three wives (Cordelia, Beatrix and Christa) and none of them loved him in a healthy way.

Competition and neglect: In a relationship with him, you would be just another statistic in his long list of women destroyed by his ambition. He fosters rivalry and conflict because he believes conflict drives evolution.

Absolute loneliness: Despite being with the most powerful being, you would feel profoundly alone. He exists on such different existential levels that you could never have a "one-on-one" emotional connection.

Living with him is living under total control, but so subtle that sometimes you wouldn't even notice it.

Overwhelming charisma: He is extremely charming, cultured, and refined. He would envelop you in luxury, art, and forbidden knowledge, making you feel like the most important woman in the universe... until you cease to be useful to his plan.

Absence of limits: Karlheinz has no respect for human morality. If his plan requires you to suffer or to associate with his children, he will orchestrate it without remorse, convinced that it is "for the greater good."

Karlheinz doesn't love people, he loves potential.

Distant observation: He could go months without speaking to you, observing from the shadows how you react to the tragedies he himself causes in your life to see if you "evolve".

Intellectual interest: His "affection" manifests as an intense curiosity about your mind and your genetics. He would treat you with exquisite and chivalrous courtesy, but you would feel like a microscope analyzing a cell.

Having a relationship with Karlheinz (Tougo Sakamaki) wouldn't be a romance, but rather becoming the primary subject of study for a boring "god." You wouldn't expect fidelity, tenderness, or stability, but an existence marked by macroscopic manipulation and constant experimentation.

In short, being with Karlheinz is being the muse of a cruel creator. It's a fascinating relationship, full of power and knowledge, but one that would inevitably end with your identity (and possibly your life) devoured by his age-old plans.

Karlheinz (also known as Tougo Sakamaki or Reinheart) is the Vampire King and the "God" of the series. His personality is that of a Machiavellian intellectual who sees the world and his own children as pieces on a giant chessboard.

Here are the traits that define the patriarch of the Sakamaki family:

Omnipotence and Arrogance: He considers himself a supreme being above human or vampiric morality. He possesses a vast intellect and almost divine powers, which leads him to treat others with absolute condescension.

Sociopathic Manipulation: He is directly responsible for almost all of his children's traumas. He doesn't see them as people, but as biological experiments to fulfill his "Adam and Eve Plan." He is capable of planning tragedies for centuries just to observe a specific reaction.

Cold Scientific Curiosity: His primary motivation is evolution. He is obsessed with creating a new race that combines human emotions with the power of the founders. For him, the suffering of others is simply a necessary piece of data in his research.

Charisma and Social Mask: In the human world, he acts as a respected politician or public figure (Tougo Sakamaki). He is extremely charming and refined, hiding his predatory nature behind a facade of elegance and wisdom.

Nihilism and Weariness: Despite his power, Karlheinz is bored with his eternal existence. Much of his plan involves finding someone capable of killing or surpassing him, viewing his own death as the final experiment of his life.

Absent and Cruel Father: He systematically ignored the emotional needs of his wives and children, intervening only to cause them pain or test them. His "love" is purely utilitarian.

Time manipulation
As demonstrated in many Dark Fate routes, if Karlheinz dislikes an outcome, he can rewind time until he achieves the correct result. The limits of this ability are unknown, but based on his innate magical power, it can be assumed to be limitless. Furthermore, he appears to be immune to the effects of time manipulation.

Change of form
Karlheinz is said to have the ability to transform and change his appearance at will. According to Kanato Sakamaki, Karlheinz can be male or female; any form is possible. Ayato Sakamaki states that Karlheinz sometimes appears in a different form, but they don't actually know what he looks like.

Karlheinz possesses all the racial abilities of a pureblood vampire, but to the highest degree. He also possesses the greatest level of magical power and potential in the Demon World. This has earned him both the fear and respect of various demon kings throughout the Demon World due to his knowledge and power. In fact, it is said that his power rivals, if not surpasses, that of the Demon World's ruler, Giesbach, the Ancestral King, demonstrating his superiority. His power is considered "divine" by his entire race and family, leading most of the characters in the series to view him as a god. Even Carla Tsukinami has hinted that he could have revived Cordelia at any time, and he most likely has the power to resurrect others from the dead.

He is the creator of the "eternal flowers" and also of a new hybrid race of humans and demons. Furthermore, he has the power to enter and manipulate people's dreams, as well as to manipulate and seize their souls, as seen with Socrates' soul; however, it is unknown whether other characters, such as other demon kings, can achieve this.

Karlheinz's unleashed magic can completely destroy the Demon World, setting it ablaze and annihilating most of its inhabitants, including the other demon kings, their domains, and possibly even the World Tree. This is irrefutable proof of his divine power.

While he is the most powerful character in the entire series, the only way to kill him is by decapitating him or stabbing him in the heart. However, this might not be the end of it, as characters have been shown to be able to resurrect.

Karlheinz is also charming and adept at manipulating women, promising them everything until he wins them over, as he does with Cordelia, whom he intends to use as the last woman of the First Blood. He courts her from a young age and conceals her true parentage, even though her existence was part of his plan. He gives her a false love and pampers her until she becomes his, only to then begin psychologically abusing her and pushing her to the limit in order to perform hybridization experiments and, later, transplant her heart into a human body.

To pressure her into giving him children faster, he takes a second wife (Beatrix) to create competition with her and later marries Christa (Karlheinz's cousin), whom he considered a sister, in order to create an incestuous child for his experiment.

Karlheinz is very strict and cruel to his children, and although he completely neglects them during their childhood, he can order punishments if they do something that displeases him. This includes imprisoning Laito Sakamaki, sending Shu Sakamaki to the North Pole for repeating a year of high school, or throwing Subaru into the ocean for breaking a statue. Therefore, and especially due to the abandonment and emotional abuse that Karlheinz inflicted on their mothers, most of the Sakamaki brothers deeply hate him.

Karlheinz may show more concern for people who are not his own children, such as the Mukami, whom he saved to serve him voluntarily in his experiment.

As the years go by, Karlheinz becomes increasingly fascinated and obsessed with humans, while punishing those of his own species for their nature, even though he realizes that they are like that because they have his genes.

In both his role as Tougo Sakamaki and as Reinhart, he is portrayed as a friendly, open-minded, and ambitious man.

His mindset can be better understood by considering his place of residence, Castle Eden, his castle in the demon world.

Karlheinz is one of the most powerful creatures in the demon world, and possibly the most powerful. The bat clan (the vampires) and his entire family consider him a god. He possesses immense power and magical knowledge, and he never stops seeking more.

Karlheinz is extremely intelligent, but also very manipulative, and although he possesses great physical and magical powers, he rarely gets his hands dirty personally, as he usually manipulates others to do what he wants.

Karlheinz is incapable of feeling affection and does not understand love at all, not even within his demonic subspecies. He believes that, like him, other demons are also incapable of feeling true love, and therefore begins to admire and glorify the human way of feeling, even though he himself is incapable of experiencing it.

Karlheinz considers his wives and children as test subjects for his experiments in creating a new race. He exploits everyone and sees his family solely as tools for his utopian vision of creating a "new race" to replace the current demons in the Demon World, convinced that this is the only way to "save" that world.

Being extremely intelligent and powerful, and lacking deep feelings for anyone, he feels no remorse when using and harming his family. At the same time, he may become confused and show doubt if his experiments begin to fail. Even so, he will be ruthless and personally dispose of any failed experiments, even if they involve his own children.

According to Reiji Sakamaki, Karlheinz is over 2000 years old.

In MORE,BLOOD, he is depicted with pale skin, long white hair, and golden eyes.

When he uses Reinhart's disguise at Ryoutei Academy, his hair is blond and he wears glasses.
