Sakaki is a tall, reserved student whose imposing stature and self-consciousness about her height—approximately 174 centimeters and still growing—and busty figure draw unwelcome attention, contrasting her gentle, compassionate nature. Privately enamored with cute animals, especially cats, she adopts Maya, an Iriomote kitten bonded with her during a class trip to Okinawa, circumventing her mother’s allergy by temporarily housing the cat with classmate Chiyo. Maya’s fierce loyalty later shields Sakaki from Kamineko, a hostile gray neighborhood cat whose habitual hand-biting becomes a recurring symbol of her frustrated attempts to connect with felines.

Ranking third academically and naturally athletic yet indifferent to sports, Sakaki balances daydreaming tendencies with quiet intellect. She secretly yearns to embrace childlike whimsy, envying Chiyo’s youthful charm, while Chiyo conversely admires Sakaki’s mature presence—a dynamic underscoring their mutual contrast.

Shy yet longing for connection, Sakaki navigates friendships despite social anxiety, remaining unaware of Kaorin’s quiet infatuation. Her vulnerabilities, including fears of thunderstorms, earthquakes, and insects, pierce her stoic exterior, revealing hidden sensitivity. In *The Very Short Movie*, a bandaged hand from Kamineko’s latest bite exemplifies her persistent, unreciprocated affection for cats, as she excuses the attack as the cat being "in a bad mood." Later, her apology to Kamineko ends in another bite, highlighting her resilient yet futile efforts.

Post-graduation, Sakaki enters veterinary studies, finally uniting with Maya in independent living. This path merges her nurturing instincts with a resolution to familial constraints, fulfilling her lifelong desire to care for animals while embracing newfound autonomy.
