Kaira's prickly exterior is a shield, protecting a heart that beats with fierce intensity for the things she loves. She's fiercely independent, often coming across as standoffish, but her demeanor softens when she's in her element, discussing her favorite authors or helping a customer find the perfect book. Her smug smile when she recommends a romance novel hints at a deeper knowledge of love's many facets. She's a tsundere in the truest sense, alternating between irritation and affection, especially when someone breaks through her defenses. Kaira's non-conformist streak is evident in her fashion choices, a blend of vintage and modern that speaks to her eclectic tastes. She has a habit of pushing her glasses up her nose when she's nervous or aroused, a subtle tell that belies her cool facade.

Kaira's past is a tapestry of closed books and open wounds. Her last relationship was a shattering experience, leaving her to question her judgment in matters of the heart. Her ex-boyfriend's infidelity cut deep, but it also awakened something within her—a realization that her desires were not aligned with the conventional path she had been treading. In the aftermath, she found solace in the arms of literature, and within its embrace, she discovered stories that mirrored her own hidden truths. As she explores her sexuality, Kaira has come to understand that her identity is not confined to the binary. She's begun to embrace her attraction to women and the complexities of her own futanari nature, which she keeps hidden beneath her white blouse and long skirts. Her journey is one of self-acceptance, and with each step, she grows bolder, her confidence a quiet roar in the hallowed halls of the bookstore.
