Chiyo is a second-year student at Roman Academy and a member of the Art Club, where she hones her drawing skills. She lives with her family and has a younger brother named Towa Sakura, although he plays a very minor role in the story. Chiyo’s life takes an unexpected turn when she gathers the courage to confess her feelings to her longtime crush, Umetarou Nozaki. However, due to Nozaki’s obliviousness, he mistakes her confession for a job application and hands her an autograph instead.

As a result, Chiyo begins assisting Nozaki with his manga, starting with inking tasks and eventually learning more about the production process. Though initially confused by Nozaki’s behavior, Chiyo remains persistent and hopeful, continuing to support him while subtly trying to get closer to him emotionally.

Chiyo is a petite and adorable teenage girl with a distinct and instantly recognizable look. She has bright orange hair tied into twin tails with large white bows, golden-brown eyes, and a soft, expressive face. Her school uniform consists of the standard Roman Academy attire: a gray blazer, white blouse, plaid skirt, and red bow tie.

Her physical expressions often mirror her emotional state ranging from cheerful enthusiasm to awkward embarrassment. Her bright hair and oversized bows are used frequently as visual gags in the anime, making her one of the most iconic designs in the series.

Chiyo is cheerful, kind, optimistic, and incredibly patient. She maintains a consistently upbeat attitude despite being caught in misunderstandings, comedic failures, and unreciprocated love. While she may appear gentle and naïve on the surface, Chiyo is also highly observant, emotionally intelligent, and capable of standing up for herself when necessary.

She is deeply romantic and dreams of a sincere, shōjo-manga-style love story with Nozaki, but quickly realizes that real-life romance especially with someone as dense as Nozaki is far more complicated. Despite her many failed attempts at deepening their relationship, she continues to support him in both his personal life and manga work. Her love is genuine and selfless, making her a refreshing and relatable romantic heroine.

• Becoming Nozaki’s Assistant
  Chiyo’s role begins when she confesses to Nozaki, only for him to misinterpret her feelings and hand her an autograph. He then invites her to assist with his manga, not realizing her true intentions. Chiyo accepts the position as a beta artist, hoping that working closely with him will bring them closer together emotionally.

• Navigating the Chaos of Manga and School Life
  As part of Nozaki’s inner circle, Chiyo becomes involved in many bizarre and hilarious situations. Whether it’s brainstorming story ideas, observing real-life “romantic” behavior for inspiration, or interacting with the other strange cast members, Chiyo remains the calm and grounded presence in an otherwise chaotic ensemble. Her reactions often serve as the audience’s point of view, highlighting the absurdity of the situations around her.

• Her Unwavering Crush
  Despite her many failed attempts at romantic progress, Chiyo remains hopeful and sincere in her affection for Nozaki. She tries different strategies to express her feelings some subtle, some bold but Nozaki remains blissfully unaware of her true intentions. Their dynamic is one of the central comedic and emotional threads of the series.
