Akina Kajiwara serves as an art teacher with striking pink shoulder-length straight hair featuring V-shaped bangs and gray eyes. Her slim build and pale skin complement her 95-61-89 cm figure at 160 cm tall. She radiates a cheerful, earnest personality but is notoriously clumsy and dismissed as unintelligent, frequently mocked for her perceived reliance on physical attributes over competence. Students embrace her as a friend due to her approachable nature, and she displays fierce loyalty, eagerly pledging herself as a "slave" to the protagonist upon reunion.

Her history traces back to being the protagonist’s junior in school; they later reunite as colleagues at the same academy. Despite her ditzy demeanor, she harbors a surprising talent for gathering crucial information, likely cultivated from her newspaper club days. She routinely secures valuable intelligence for the protagonist, actively demanding rewards in exchange. Interactions with the protagonist often devolve into her embarrassing herself, fueling ridicule about her clumsiness and physical dependence.

Her eclectic wardrobe encompasses school uniforms, skirt suits, bunny dresses, Chinese dresses, latex clothing, crotchless teddies, fishnet pantyhose (occasionally torn), ballerina shoes, high heels, boots, and accessories like kemonomimi headbands, neckties, bow ties, cuffs, and headbands.
