TV Special
Description
Queen Sakura Aldia Vespaland is the queen of the Kingdom of Vespania, a fictional absolute monarchy in Turkey, and the character whose death sets the entire story of Lupin III vs. Detective Conan in motion. Although she appears only briefly at the beginning of the special and is otherwise remembered through the words of others, she is essential to the plot because the mystery surrounding her death is the central case that the story resolves.

Her background is that of a ruling monarch and mother. She is the mother of Princess Mira Julietta Vespaland and Prince Gill Cowell Vespaland, and the older sister of Duke Gerard Musca Vespaland, who serves as the Prime Minister of Vespania. The story opens during a hunting party in the royal family's private forest. The queen does not take part in the hunt because she dislikes hunting, which she considers a barbaric activity. Instead, she separates herself from the hunters and stands quietly near a cherry tree that she treasures. While she is there, she is shot and killed. The version of events accepted by the public is that her son Prince Gill accidentally shot her and then, overwhelmed by guilt, took his own life. Later in the story it is revealed that this account is false. Her brother Gerard murdered her, killed Prince Gill as well, and staged the scene to resemble an accidental shooting followed by suicide in order to clear his own path to power.

Her personality is portrayed as gentle and warm. She is described as a kind-hearted ruler who loves nature and is displeased by violence such as hunting. She is also a noted admirer of Japan, and she had personally planned a royal reception at a hotel in Tokyo, an event that her daughter attends after her death. Her devotion to the cherry tree she was watching when she died is one of her most significant character traits, and it becomes a key piece of evidence in the investigation. Because her son Gill knew how much she cherished that tree, the discovery that a bullet had damaged one of its branches proves that Gill could not have fired the shot, since he would never have harmed anything she loved.

Her motivations are not explored in depth because she dies before the main events of the story. What is shown of her actions suggests a queen who took her responsibilities seriously, engaged in international events, and cared for both her family and the natural world of her kingdom. Her death is the event around which everyone else's motivations form. It leaves her daughter Mira as the heir to the throne, creates a succession crisis that divides the kingdom, and draws the detective Conan and the thief Lupin into an investigation of what really happened in the forest.

Her key relationships define much of the story. With her daughter Mira, she is a mother whose sudden loss leaves Mira grieving and unwilling to accept the throne; Mira's eventual decision to embrace her duties is shaped by visiting the place where her mother and brother died. With her son Gill, her relationship is tragic because he is initially blamed for her death, and the eventual proof of his innocence is closely tied to the memory of her gentle character. With her brother Gerard, her relationship is the dark center of the plot, as he is the one who ends her life for his own ambition.

Because she is dead from the outset, her character does not undergo development in the usual sense. Instead, the story develops her posthumously. She first appears as the victim of a terrible accident, but by the end of the special the truth redefines her as the victim of a calculated political murder. In terms of notable abilities, she has no special powers, combat skills, or investigative talents. Her importance comes from her position as the absolute sovereign of Vespania and from the personal qualities she was remembered for, particularly her love of nature and her affection for the cherry tree, which ultimately serve as the clue that reveals the truth about her death.
