Description
Tsutsukakushi Tsukiko is a first-year high school student of slender build, below-average height, and fair skin. She possesses shoulder-length light grayish hair tied in a left side tail, featuring a small braid resembling a "cat tail" on the left side of her head, and warm grey-blue eyes. Her typical attire is the school uniform: a white shirt, red checkered skirt, and black knee-length socks, accessorized with a pale pink hairpin holding back her bangs and a bright pink bow. Her childlike appearance and petite stature create a cat-like impression noted by others.
Orphaned young after her parents' deaths, she lives with her older sister Tsutsukakushi Tsukushi. The sisters share an extremely close bond forged through early reliance, though their relationship strains when Tsukushi develops intense romantic feelings toward her. A childhood fight prompted Tsukushi to wish upon the Stony Cat statue for reconciliation, resulting in the shrine's creation central to the story.
Initially shy and emotionally expressive, Tsukiko wished upon the Stony Cat to become more mature and less transparent emotionally. This wish backfired, leaving her unable to display facial expressions or vocal inflections despite feeling emotions internally. Her underlying personality remains sensitive, insecure, and prone to loneliness, contrasting her outwardly stoic demeanor. She demonstrates strong will and bravery when protecting valued things, alongside traits like an exceptionally large appetite—particularly for meat buns—and skills in cooking, drawing, crane games, and card games like Old Maid.
Her relationship with Yokodera Youto defines much development. They first met years earlier when she volunteered masked at a nursery school; Youto guided her interactions with children. He later forgot this encounter due to sacrificing his memories in a childhood wish. They reunite at the Stony Cat shrine while discarding unwanted traits, triggering an alliance to reverse their wishes. Tsukiko develops deep romantic feelings for Youto, becoming possessive and jealous—especially toward Azuki Azusa. She creates a "point system" documented in notebooks, recording his interactions with other girls to demand compensation like holding hands. This system secretly stems from an unconscious wish to preserve Youto's memories after learning of his self-sacrificial nature.
Her character evolves through later events. After Youto sacrifices his lifespan to save Tsukushi from a family curse, Tsukiko falls into despair and becomes trapped in a time loop. Her wish to "remember everything in Youto's stead" allows her notebooks to persist across loops, enabling her to retain memories while desperately attempting to prevent his repeated deaths. The loops end when Youto realizes his mistakes with Emi's help, leading them to travel back and eliminate the curse's origin—a belief held by ancestor Tsukasa. This journey reveals Youto's past connection to the Tsutsukakushi family originated from Tsukasa's wish for companionship during loneliness.
In the new timeline negating past wishes, Youto grows distant. Tsukiko, retaining memories through her notebooks, confronts him at the Stony Cat shrine and forces him to read her records to rebuild their relationship. She initially obsesses over perfectly recreating the past but learns through Youto to embrace the present and allow relationships to form naturally. They ultimately burn the notebooks, symbolically accepting that essential memories endure without artificial preservation. By the light novel's conclusion, they establish an official romantic relationship and live together.
Her rivalry with Azuki Azusa begins contentiously; Tsukiko asserts superiority during a field trip under the guise of discussing a hypothetical love triangle. Azusa challenges Tsukiko's possessive approach, arguing love requires mutual acceptance rather than rankings and questioning the genuineness of Tsukiko's feelings. This confrontation leads Tsukiko to recognize her selfishness, reconciling with Azusa to form a friendship marked by affectionate nicknames.
