Movie
Description
Gruier Serenity is the seventh princess of the Serenity Planet Commonwealth royal family. She was born approximately thirteen years before the events of the main story, having been created from an artificial womb aboard the legendary Golden Ghost Ship, a vessel that also housed the bio-plant used to generate royal offspring. This unique origin ties her directly to the central political and familial conflicts of her star nation.
Standing 140 centimeters tall and weighing 34 kilograms during her first appearance, Gruier has blonde hair and blue eyes. Her hairstyle is variable, often styled in twin buns with braided tails for casual occasions or worn in loose locks for formal ceremonies. At Hakuoh Academy, where she enrolls as a student, she wears the standard middle school uniform, supplementing it with a black Yacht Club hoodie for club activities. For royal functions, she dons elaborate white gowns adorned with frills, ribbons, tiaras, and white roses.
Despite her high royal status, Gruier maintains a friendly and sociable demeanor, actively preventing her position from hindering personal interactions. She is not overly formal and can be approachable, though her sheltered upbringing within the palace initially leaves her naive about certain everyday matters. She tries to be helpful and dislikes being left out of important situations. At the outset of her journey, she has a tendency to withhold critical information from her allies, a habit born from her politically sensitive mission and one she later expresses genuine remorse over. As she adapts to her responsibilities and becomes more integrated with the Bentenmaru crew and her new friends, she grows more transparent and trusting.
Gruier’s primary motivation stems from a period of political unrest within the Serenity Commonwealth. Aligning herself with the reformist faction, she comes into conflict with her younger sister, Grunhilde Serenity, who holds opposing views on the monarchy's future. Tasked by the grand duke, Gruier seeks to find the legendary Golden Ghost Ship with the specific intention of destroying the bio-plant aboard, believing this act will help resolve the political conflicts within her family. To accomplish this, she seeks the assistance of the pirate ship Bentenmaru, using a special ID ring given to her years earlier by its former captain, Gonzaemon Kato, which grants full system access. Her initial boarding of the Bentenmaru is achieved by stowing away, a recurring behavior that earns her the nickname Stowaway Princess.
Within the narrative, Gruier serves as both a catalyst for the Golden Ghost Ship arc and a key supporting figure. Her role extends into the film Abyss of Hyperspace, set during the spring break before the next school year. During this time, she helps the Hakuoh Academy yacht club with preparations for their recruitment drive, using her artistic talent to paint an image for their promotional posters. She interacts with the new character Kanata Mugen, commenting on the legacy of Captain Gonzaemon. She also observes her sister Grunhilde's interest in Kanata and engages in private conversations with her, emphasizing the importance of personal encounters. Following the film's events, Gruier is featured in a magazine article concerning the Serenity Commonwealth's takeover of former Yggdrasil Group companies, and she also sends Kanata an official letter of congratulations.
Her key relationships are central to her character development. She shares a particularly strong bond with Marika Kato, the current captain of the Bentenmaru, whom she deeply admires for operating without the constraints of royalty. She respects Marika's judgment and supports her during crises, even assisting in operating the ship. She also develops a budding friendship with Chiaki Kurihara, bonding with her over their shared connection to Marika and enjoying more mature conversations. Her relationship with her sister Grunhilde is initially strained due to their ideological conflict, but they eventually reconcile. She also holds the memory of Gonzaemon Kato in high regard and is visibly distressed upon learning of his death.
Throughout the story, Gruier demonstrates significant development. She begins as a resourceful but secretive stowaway on a personal mission, but her experiences aboard the Bentenmaru and at Hakuoh Academy teach her the value of trust and friendship. She learns to be more open about her intentions and feelings, reconciling with her sister and becoming more comfortable in her dual role as a princess and an active, contributing member of the yacht club. She increasingly disregards strict royal protocols when necessary, showing adaptability and a willingness to employ creative or unconventional methods to achieve her goals.
Gruier possesses a number of notable abilities. Her royal education has honed her skills in diplomacy and the arts of statecraft, which includes a refined ability to detect falsehoods, effective unless the speaker fully believes their own lies. For space travel, she has theoretical piloting knowledge of dinghies learned from simulator training and gains operational familiarity with the systems aboard both the luxury yacht Odette II and the pirate ship Bentenmaru. She is a capable painter, a skill she puts to use for the yacht club's recruitment drive. Counterbalancing these skills is her notable inability to swim. However, her most famous talent is her remarkable and repeated ability to stow away on spacecraft, often bypassing advanced security systems, which cements her reputation as the Stowaway Princess.
