Description
Satō Matsuzaka is a 15-16-year-old high school freshman born on December 31st. Orphaned young in an unspecified accident, she endured physical and sexual abuse under her aunt's custody, warping her understanding of love into accepting mistreatment as affection. This left her emotionally scarred and incapable of recognizing genuine love, leading to numerous bitter, transient relationships.
Physically, Satō possesses fair skin, thigh-length light bubblegum pink hair often tied in small side buns, and dark-crimson eyes. She typically wears her Makisuhara High uniform: a brown vest, navy blue blazer, green skirt, black knee-high socks, and brown shoes. She carries a blue bag holding defensive tools, including a taser and knife, used for protection or violence.
Externally, Satō projects a kind, polished persona, excelling academically and maintaining popularity. She works part-time at places like Cure á Cute or the Princess Imperial restaurant to fund her hidden life. This affable façade masks a deeply manipulative and obsessive nature. Her personality shifts drastically when her "Happy Sugar Life" with Shio Kōbe—a young girl she found abandoned—is threatened. For Shio, her sole source of "sweet" love, Satō justifies extreme actions like deception, blackmail, and murder, dismissing others' love as "bitter" or corrupt.
Her relationship with Shio defines her. She kidnaps Shio, confines her to their apartment ("castle"), and isolates her, claiming protection. Satō financially sustains them through part-time work and household management, expressing affection with gifts like cakes. Her devotion escalates to buying wedding rings and performing a pseudo-marriage ceremony, symbolizing an eternal bond. Despite controlling behavior, she avoids sexualizing the relationship and prioritizes Shio's well-being, culminating in self-sacrifice.
Her other relationships are transactional or hostile. She manipulates her abusive aunt into aiding cover-ups, leveraging their history while harboring deep resentment. She murders her only friend, Shōko Hida, after Shōko discovers Shio. She exploits coworkers like Taiyō Mitsuboshi and her teacher Daichi Kitaumekawa—using blackmail (e.g., threatening Daichi with exposure) to remove obstacles. She kills individuals endangering Shio, like an artist boyfriend who tried to strangle Shio, and later dismembers an ex-boyfriend attempting blackmail.
Her criminal actions intensify as her life unravels. After murdering Shōko, Satō stages an elaborate plan to fake her death: dressing Shōko's corpse in her clothes and coercing her aunt into burning down their apartment to destroy evidence. The plan falters when she returns for her forgotten wedding ring, leading to a rooftop confrontation with Shio's brother, Asahi. Cornered and refusing to surrender Shio, Satō jumps with her. During the fall, she prioritizes Shio's survival over shared death, positioning herself to absorb the impact. She dies instantly; Shio sustains non-fatal injuries.
In the aftermath, Shio keeps Satō's ring and hair ribbon, internalizing their bond by claiming to have "become" Satō, leaving Asahi devastated and underscoring the irreversible impact of Satō's actions.
