OVA
Description
Kanata Futaki is a student at the same academy as the other characters, holding the powerful position of the Public Morals Committee chairperson and also serving as the head of the girls' dormitory. Her official character data lists her birthday as October 13, a height of 163 centimeters, and A blood type. She is a classmate of Haruka Saigusa and becomes the roommate of Kudryavka Noumi after the heroine Kud is assigned to her dormitory.

Kanata presents herself as a strict, cold, and unsociable individual who speaks in a sharp, unyielding manner. As the enforcer of school rules, she is openly hostile toward students she perceives as disruptors of public morals, which frequently puts her in direct opposition to the mischievous members of the Little Busters group, particularly her classmate Haruka. On the surface, she appears ruthless and devoid of emotion, but this demeanor is largely a facade that conceals a deeply caring and protective nature. Her personality is defined by this conflict between her genuine compassion and the cruel role she is forced to play.

The primary motivation behind her behavior lies in her secret family background. Kanata is the older twin sister of Haruka Saigusa, though this relationship is not initially apparent to others. The two sisters are caught in a complex and abusive family structure orchestrated by the Saigusa family and their uncle. To shield her younger sister from physical abuse and exploitation, Kanata willingly takes on the role of the family's heir and enforces a strict separation between them by appearing as Haruka's enemy. Her actions as discipline chair are a calculated strategy to keep Haruka at a distance, thereby protecting her from the family's manipulative grasp and a strategically arranged marriage. This heavy burden causes Kanata to suppress her own happiness for the sake of her sister's safety.

In the story, Kanata serves as the primary antagonist in Haruka's personal arc before the truth is revealed. She wields her authority over Haruka, reprimanding her for any infraction and even employing Kudryavka's dogs, Strelka and Belka, to help patrol the school and track down rule-breakers. Her role extends beyond mere disciplinarian; she is a tragic figure whose harsh exterior masks a desperate attempt to save her sister. Her own route in the narrative focuses on the protagonist discovering her secret and the subsequent effort to free both sisters from their family's control.

Her most significant relationship is with her twin sister, Haruka Saigusa. The two are physically very similar, with the primary differences being their eye color, hairstyle, and dominant hand. Kanata is skilled at cooking, unlike Haruka, and she can tolerate mint flavor which her sister dislikes; these small details sometimes help others tell them apart when Kanata impersonates Haruka using colored contact lenses. Another key relationship is with her roommate, Kudryavka, whose friendship provides a rare, neutral space where Kanata's strictly professional demeanor can soften slightly. She is also known to be one of the few people who can be intimidated by the formidable Yuiko Kurugaya. The former dormitory head, known as A-Chan, affectionately calls her Kana-chan, a nickname Kanata visibly dislikes.

Throughout her character arc, Kanata undergoes significant development. Initially believed to be a cold-hearted villain, her motivations are recontextualized when her past is revealed. She carries physical and emotional scars from her childhood, including marks on her arms from being hit with a belt, a testament to the abuse she endured to protect her sister. Her journey involves allowing others to see her vulnerability and finally accepting help. The narrative concludes with a reconciliation where she can be saved from her self-imposed isolation, leading to a more open and genuinely happy life. In the spin-off work Kud Wafter, she has matured fully into her role as the strict but fair leader of the girls' dormitory, demonstrating that she has retained her sisterly devotion while maintaining order.

Notable abilities include her effectiveness as an administrator, maintaining order through rigorous efficiency and the clever use of resources like tracking dogs. She is also a capable cook, which stands in stark contrast to her sister's lack of skill in the kitchen. In addition to her administrative duties, she serves as the captain of the girls' kendo club team, demonstrating physical prowess and discipline. She has specific physical sensitivities, including an allergy to citrus fruits and cat hair, while conversely enjoying the scent of mint.
