Amalie Mainbach

''Amalie Mainbach, previously and in the future Amalie von Benno Baumeister, is one of the major female protagonists in "Hachinan tte, Sore wa Nai Deshou!" She is the widowed sister-in-law and mistress of Wendelin Baumeister. She was married to Wendelin's oldest brother Kurt von Benno Baumeister prior to his death. While married to Kurt she took the surname Baumeister; However, after his death Wendelin von Benno Baumeister advised her to change her last name back to Mainbach to avoid some of the stigma and being ostracized by her deceased husband's actions. In the future she will become Wends sixteenth wife. ''

Appearance
Amalie is not considered beautiful, but she is attractive. She has a childish face that hides that she is a woman in her prime.

Personality
Amalie is a very kind and soft-spoken woman. She is abundantly aware of her social standing and how women don't typically have a voice in matters and, therefore, she stays out of the matters despite being one of the best educated people in the territory.

Because of the inability to connect on an intellectual level with so many within the Baumeister Knighthood, she cherishes contact with her brother-in-law Erich, who is about as educated as she is, as well as her other brother-in-law Wendelin, who despite being 12 years her junior, is far more knowledgeable. When they are away from the territory, she writes and receives letters as often as the merchant caravans allow.

She was longing for a marriage out of love as depicted in the books back home, despite knowing that it was a political marriage with Kurt. She didn't receive the love she was looking for till she becomes Wends lover/mistress.

Background
Amalie is the daughter of a Knight peerage household and her marriage to Kurt was arranged between the households.

Plot
She was 18 at the time, making her 13 years older than Wend and six years younger than Kurt. She bore Kurt two sons named Karl and Oskar.

A few months after her husband's death, her father-in-law, Artur von Benno Baumeister, arranged for her to become a sex-teacher for the soon-to-be-married Wendelin, but they fell in love and the relationship continued after his marriage. She became one of his mistresses and eventually gave birth to his daughter, Rosina.

Abilities
Amalie has normal human mana, which means she cannot use magic. At one point in the novel, Wend discovers that sexual relations with him cause the other wives to increase in mana beyond their previous upper limits, however he notices no such increase in her mana, causing him to surmise that a person must have magical talents first to allow that effect. He is somewhat saddened that even with such a discovery she will not be able to learn magic.
 * The discovery that intimate relations between Wend and his wives that allows for an increase over previous mana capacity caps is considered a critical secret that could dramatically alter politics from local to international levels if it were to become more widely known; for this reason, the only people who know about it right away are Wendelin, his wives, Amalie, his retainers Erwin and Roderich, Burkhart, Klimt Kristoff von Armstrong, Margrave Bleichröder and King Helmut.

Amalie was raised to be able to read, write, and perform even relatively complex math calculations, and can do so at a level similar to that of fifth son, Erich. Once Erich and Wend leave the domain, she and the main-village chief, Klaus, are the only people at the head of the territory that can reliably do so. By comparison, her husband Kurt's scholastic ability is considered particularly poor even in comparison to the poor educational state of the territory.
 * The fact that she can read and write is why, in both the novel and anime, the older brothers comment to Wend while at Erich's wedding in the capital that the letter from Artur indicating they have no money to send wedding gifts was almost certainly written by Amalie.

Trivia

 * Amalie's closest companions are Therese and Lisa - the trio are also the three oldest members of Wend's harem.
 * She is encouraged by Therese to do her best to get pregnant after all of Wend's wives get pregnant. While Wend is encouraged by Rhodrich.
 * Wend makes her use the name Wend-Kun, just like when he was a child and not call him Earl.
 * Even though she didn't become able to use magic after having slept with Wend, their daughter Rosina, and her descendants are able to.
 * She agreed to be Wend's sex teacher for the sake of her children, as she didn't believe that she could have that kind of luck with Wend giving a peerage and land to her children. She believed things like that didn't happen.
 * The rumor about her and Wend: "She has offered herself as atonement for her husband, who tried to assassinate his younger brother”
