Ichiko Rokujō teaches elementary school, specifically instructing Hime Gotō. Her initial appearance features tan skin, short brown hair held by a white hairclip on the left, and brown eyes. She consistently wears a red-and-white tracksuit, projecting a sporty, casual image. Years later, her appearance transforms dramatically; she grows her hair long and adopts conventional feminine attire like a blue dress. This shift starkly contrasts her earlier tomboyish style, making her nearly unrecognizable to past students.

Ichiko bubbles with high energy, enthusiasm, and determination. She tackles tasks with excitement and rarely abandons them easily, persistently striving to integrate into social circles and forge friendships. She demonstrates fierce loyalty, actively aiding Kakushi Gotō in concealing his profession as an erotic manga artist from his daughter, Hime. This role as a steadfast secret-keeper defines her across different periods.

She harbors unrequited romantic feelings for Kakushi, which she keeps discreetly hidden. These feelings sometimes surface as jealousy, particularly during events like the school sports festival when Kakushi interacts with other women. Despite her deep emotional investment, her reliability in protecting his secret remains unwavering, even without reciprocation.

In narrative segments set years after the main events, she reunites with Hime’s former classmates. Her evolved appearance and demeanor reveal her growth beyond her initial role, yet her core traits of supportiveness and dedication endure. She maintains connections with characters from Hime’s childhood, reflecting relationships forged during her time as their teacher.

Her surname, Rokujō (六條), derives from the Japanese words for "six" (六, roku) and "article" or "ray of light" (條, jō). Her given name, Ichiko (一子), translates to "child" or "the only child".
