Lotte Birenkofen

"“I love you, Eric, my master. We'll always be together forever.” —Lotte" Lotte Birenkofen (ロッテ・ビレンコーフェン) was the princess of the Grand Nation of Birenkofen and a feared fighter throughout the kingdom and across the Land of the Six Shields. She is the childhood friend and lover of Eric Aretoze who made her into a slave maid as a means to save her life. The two would soon become the new rulers of the Kingdom of Aretoze and establish the Six Shields Empire. She, along with Eric, became Grandwalkers after vanquishing Romanov I at the cost of their lives. They also have a son named Kunimi Birenkofen-Aretoze, though he would be named Hajime Hinobori six-thousand years later after being awakened and discovered in the present day.

Personality
As the princess of her kingdom and the most skilled warrior, Lotte would not underestimate her opponents but would not also be lenient towards them at all. In the battlefield, she would do her best to keep her mind in the battle no matter how desperate the situation was. Generally, Lotte is kind and charitable woman.

Background
She was the princess of Birenkofen and the most promising candidate for succession to the throne, since she had no siblings. From an early age, her father grew up in political affairs and war, and her mother was devoted to social circles and her affection was weak. Because of this, she often hungry for her affection and tantrums from an early age, annoying the caregivers around her. Her tantrums became increasingly more aggravating as her parents broke down and her family ties broke. She had the opportunity to heal her emotions after she met a foreign young prince named Eric Aretoze. Since then, she started to turn around and had become less likely to have a tantrum. While she was spending time with Eric, she fell in love with him, and although it was a twisted expression, they vowed to marry each other in the future. Because she was a princess of a powerful country, many outside princes proposed to become her groom because of her outstanding appearance, but she refused all of her because of her childhood promise to Eric. She also devoted herself to swordsmanship and martial arts after she was appointed as the commander of the Knight Division of the army at the age of twelve by the kingdom's custom, without being able to put up with her decorations. Blessed with abilities from many good teachers and talents blossomed, she became a warrior who could turn the battlefield into a pool of death, and even if she would be bathed in blood, she would stand coldly on the battlefield. She was feared in and out of the kingdom as the "Witch of Birenkofen".

Eric Aretoze
During Eric's childhood spent as a hostage in the Birenkofen country, he and Lotte first met each other and grew to become very fond with each other's company. After several months of knowing the other, the relationship of the two children blossomed and fell in love with each other. They promised to become proper suitors for and marry each other in the future. After Eric returned home to his country, they went their separate ways but continuing thinking about each other and the promise they made long ago. She believed that she was closer to her childhood lover Eric far more so than her family. However, as the two grew up, by the time they would reunite, their relationship would take an ambiguous and uncertain turn. She was at the edge of her inner despair, remembering her crazy shock that her beloved had attacked and destroyed her own kingdom. Her only hope now was that she would kill her betrayed childhood friend and let her know. She kept her cold, dark blade in her heart, contrary to Eric's thoughts.
