Eric Aretoze is a primary character from the adult anime OVA series Dorei Maid Princess, which is itself based on a visual novel. Physically, Eric is depicted as a young adult male with short blue hair that reaches approximately to his ears and possesses blue or turquoise-colored eyes.

Eric’s background is deeply intertwined with political intrigue. He is introduced as a foreign prince who was held as a political hostage in the Grand Nation of Birenkofen. It was during this period of captivity that his relationship with Princess Lotte Birenkofen began. Despite the circumstances of his presence in the kingdom, he and Lotte developed a close bond, which provided her with emotional stability and eventually blossomed into mutual affection. The two exchanged promises of future marriage, a vow Lotte would honor even as she rejected numerous other suitors.

However, Eric’s true nature and motivations prove to be far more complex and ruthless than his role as a hostage prince would suggest. His primary motivation shifts from romance to conquest, as he ultimately betrays Lotte and her kingdom entirely. He leads an attack that destroys the Grand Nation of Birenkofen, capturing Princess Lotte in the process. His actions are driven by a desire for power and control, demonstrating a capacity for extreme cruelty and manipulation.

In the story, Eric serves as both the antagonist and the master to whom the protagonist, Lotte, is subjugated. Following her capture, he does not execute her but instead forces her into a new role to prolong her life. He subjects her to degrading training to become a slave maid, a position that combines sexual servitude with the high-risk duties of a bodyguard. This process is designed to break down her will and repurpose her formidable combat abilities for his own protection and pleasure. His role is defined by this dynamic of captor and master, driving the central conflict of the series.

The key relationship in Eric’s life is, without question, his relationship with Lotte Birenkofen. This relationship undergoes a dramatic transformation, evolving from that of fellow hostages and romantic partners to enemies, then to master and slave, and finally, to something more reconciled. Though Lotte initially contemplates killing him for the destruction of her homeland, their dynamic eventually changes. Despite his initial brutality, Eric and Lotte ultimately reconcile and become co-rulers of the Kingdom of Aretoze, later founding the Six Shields Empire. Their union produces a son, showing a complete reversal from their initial captor-captive dynamic. Their story ends when they sacrifice their lives together to defeat a powerful foe named Romanov I.

Eric’s personal development is marked by this radical shift from a seemingly romantic figure to a conquering tyrant and finally to a co-ruling partner. While the narrative provides little information on specific abilities, his most notable traits are his political cunning and strategic military leadership, which allowed him to destroy an entire nation from within, and his psychological manipulation skills, evident in his calculated training and conditioning of Lotte. He does not possess any bestial or non-human physical traits.
