Ayse, whose full name is Armut Ayse, is a significant supporting character in the narrative. She is the young daughter of Sultan Fatma of the Balta Stratocracy, making her a princess of that realm. She is also the elder sister of Kemal and the only niece of the powerful sultans Baraban and his successor Beyazit.

In terms of appearance, Ayse is considered a beauty by many, despite her typically serious and stoic demeanor. She has long, dark, wavy hair that is often styled in segmented ponytails, and her melancholic expression is accentuated by her long eyelashes. Her attire usually consists of a long, draped pink dress with a high collar, worn over matching salwar trousers, and she often wears a jacket with open sleeves over the dress, completing her outfit with red shoes.

Ayse's personality is defined by her stoicism and bluntness. She is known for speaking her mind directly, even if it may hurt the listener's feelings, as demonstrated when she first meets the protagonist Mahmut and calls him stupid and naïve. Beneath this harsh exterior lies a highly intelligent and proud individual with a powerful sense of justice and responsibility. She is not ruled by her emotions and is prepared to make difficult sacrifices for the greater good. This is starkly illustrated after a civil war when she pushes for the execution of her own mother, Fatma, for committing treason against their nation. Despite her serious and aggressive side, Ayse shows a much gentler and kinder personality when she is around her uncle, Beyazit.

Ayse's primary motivation is the welfare and stability of her homeland. She has a strong sense of duty, which leads her to accept her arranged marriage to Sultan Orhan of the Kilic Stratocracy without personal complaint, understanding it as a political necessity. Her role in the story is that of a key political player and ally to the main characters. Initially opposed to the political direction of her own mother, she becomes involved in a rebellion to overthrow the existing sultans of the four stratocracies who are conspiring with the Balt-Rhein Empire. Her plan to gather all the sultans in one place by announcing a date for her wedding to Orhan is a pivotal moment that sets the stage for a major political upheaval.

Key relationships heavily define her character arc. Her loyalty to her uncle, Beyazit, is a significant exception to her normally reserved nature. Her relationship with her fiance, Orhan, is complex; while she accepts the marriage as her duty, she confesses to Beyazit that she had once thought they might marry one another, hinting at unspoken personal feelings. This moment is overheard by a heartbroken Orhan, adding emotional depth to their political union. Despite this, she remains a figure for whom Orhan is willing to become a better leader.

Throughout the story, Ayse undergoes notable development. She begins as a princess attempting to orchestrate a coup against her own mother's rule, a move that labels her a traitor. After the civil war concludes, she is rewarded for her loyalty and political acumen by being promoted to the title of Vizier-i-Azam, the highest-ranking official. In this new role, she is placed in charge of her younger brother Kemal's education until he turns fifteen and officially succeeds the throne. This transition marks her shift from a rebellious princess to a responsible state leader and guardian of the future sultan.

Regarding her abilities, Ayse is not a frontline warrior but a formidable political operator. Her greatest strength lies in her skill as a politician and strategist. Like most citizens of the Turkish stratocracies, she is also a capable horse rider. Her intelligence, daring, and unwavering commitment to her principles make her a valuable and respected figure in the struggle for the nation's future.
