Ushio Noa生塩ノア

Secretary of Seminar, Millennium Science School’s student council

Ushio Noa is a supporting character in the game Blue Archive and the secretary of Seminar, the student council of Millennium Science School. A second-year student, she handles meeting records as well as administrative work concerning the school’s inventions and patent applications. Her nearly flawless recall makes her especially suited to the job.

Noa speaks with composed courtesy, notices details that others miss, and can turn a mild smile into a surprisingly pointed question. Alongside fellow Seminar member Hayase Yuuka, she helps keep Millennium functioning amid its ambitious projects and frequent disruptions.

Biography

The Secretary of Seminar

At Millennium Science School, Noa serves as secretary to Seminar. Her duties extend beyond writing minutes: she maintains records of decisions and meetings and takes part in the school’s administrative review of student-made products and patent matters. With her unusually reliable memory, she can retain information from a single hearing or reading and retrieve details that other people would overlook.

Working Beside Yuuka

Noa works closely with Seminar treasurer Hayase Yuuka. Where Yuuka is direct and often visibly exasperated by Millennium’s chaos, Noa is generally measured and lightly teasing. Their contrasting approaches become useful in situations requiring both detailed records and immediate practical decisions.

The Halo Festival Preparations

When Millennium prepares to host the Kivotos Halo Festival, Noa and Yuuka face an enormous coordination job. Yuuka is so overworked that, after drinking the herbal tea Noa offers her, she promptly falls asleep. Noa asks Sensei to help oversee the preparations while Yuuka rests, then visits other departments to deal with outstanding tasks. A damaged cheer robot becomes a larger problem when its replacement is hijacked; Noa helps trace the interference and bring the preparations back under control. Her calmness here has a practical purpose: she wants the festival to succeed without leaving Yuuka too exhausted to enjoy it.

Beyond the Council Office

Noa's work brings her into contact with the Game Development Department and other Millennium groups, particularly when their projects involve Seminar's resources or authority. Her value is not confined to taking minutes: she can compare conflicting accounts, uncover overlooked discrepancies, and help determine what her fellow council members need to address.

Personality and Motivations

Noa is outwardly calm, attentive, and polite, with a mischievous sense of humor that often appears in the form of gentle teasing. Rather than competing with Yuuka’s intensity, she tends to let a carefully chosen observation do the work. She can appear almost impossible to rattle, although serious threats to students can prompt an unmistakably earnest response.

Her extraordinary recall is more than a convenient trick. Noa takes wording, accountability, and the difference between what someone intended and what was actually decided seriously. In tense situations she can be tactful without being permissive: her measured questioning of Koyuki demonstrates how effectively she can press for responsibility without raising her voice.

Noa also has a creative side. Reading and recitation are among her stated interests, and a poem she authored won the Millennium Prize despite being teased for its densely metaphysical wording. Her literary interests sit neatly alongside her command of records and language.

Appearance

Noa has long, silvery white hair, straight bangs, and pale violet eyes. A blue-accented double-ring halo floats above her head, while angular white-and-blue ornaments frame the sides of her hair. These features are visible in her official character design.

Her standard Millennium uniform combines a white jacket, navy trim, bright blue tie, and short pleated white skirt with dark tights. She wears a loose white-and-blue outer layer, and an ID badge hangs near her waist.

Abilities

Exceptional recall

Noa can remember almost everything she has seen or heard after a single encounter, making her an invaluable recorder of decisions and small discrepancies.

Recordkeeping and administrative review

She maintains Seminar’s proceedings and takes part in patent-related and product-assessment duties tied to Millennium students’ inventions.

Careful investigation and coordination

Noa helps follow suspicious discrepancies in records and organizes or requests assistance from other Millennium departments during demanding situations.

Relationships

Hayase Yuuka

Fellow Seminar member, treasurer, and close colleague

Yuuka manages Millennium's finances while Noa maintains Seminar's records. They trust each other in difficult situations, and Noa gently teases Yuuka's earnest reactions. During Halo Festival preparations, Noa is also attentive to how thoroughly Yuuka has overworked herself.

Tsukatsuki Rio

Seminar president and senior student

Rio leads the council in the earlier Millennium story. Noa knows her as a decisive, sometimes difficult-to-understand superior; the consequences of Rio’s choices are explored in later spoiler material.

Kurosaki Koyuki

Younger Seminar member

Koyuki’s tendency to make excuses clashes with Noa’s accurate recollection. Noa can secure a more serious response from the junior student simply by asking carefully phrased questions.

Sensei

Adult adviser and occasional collaborator

Noa works with Sensei during Millennium’s Halo Festival preparations and later responds to requests for information and help. The game gives this relationship a warm, respectful, occasionally playful tone.

Interesting facts

Noa's poem 'The Meter of Memory' won the previous Millennium Prize. The presenter jokes that its long metaphysical terms made it an effective cure for insomnia.

It is a rare glimpse of her creative work—and a dry joke at the expense of a secretary known for precise language.

Her original design credits Hwansang and illustrator DoReMi; the separate Pajamas version lists Owa and dydldidl instead.

The credit change distinguishes Noa's original character design from the artists responsible for a later outfit variant.

Major story spoilers below.

Rio’s Hidden Project

In Volume 2, Chapter 2 of the main story, Rio takes Aris away. Noa and Yuuka investigate on Sensei’s request, notice irregularities in Seminar’s spending, and recover concealed information about Eridu, an enormous fortress city Rio built in secret. Noa is shocked by the scale of what her president has done. Although the pair initially offer information rather than direct intervention, Noa’s insight into Rio’s uncompromising decision-making helps explain how the situation arose.

Intervening at Eridu

When the crisis escalates inside Eridu, Yuuka and Noa go further than merely supplying coordinates. As the city’s systems are taken over and the hostile protocol approaches completion, Yuuka calls for a power shutdown and Noa acts immediately. The interruption stops the resource-acquisition process long enough to give Aris and her allies another chance. Noa later confirms that Yuuka insisted they see their assistance through to the end.

The Final Volume Emergency

During the Final Volume’s response to the false sanctums, Noa coordinates with Millennium teams trying to access Eridu and counter Hod. Rio’s password protection creates a serious obstacle. At Yuuka’s suggestion, Noa helps bring Koyuki out of the Self-Reflection Room so her unusual aptitude can be put to use. The scene emphasizes Noa’s mixture of practical judgment and formidable personal authority: Koyuki abandons her excuses under Noa’s pointed questioning.

Spoiler questions

How does Noa help reveal Eridu?

She and Yuuka examine altered or concealed Seminar records, uncover discrepancies in financial information, and identify the secret fortress city where Rio has taken Aris.

Does Noa help stop the crisis at Eridu?

Yes. After Yuuka orders the city’s power shut off, Noa takes action; the interrupted system is unable to finish acquiring the resources needed for its hostile protocol.

Why does Noa bring Koyuki back during the Final Volume?

Millennium needs someone able to tackle security imposed by Rio. Noa and Yuuka recruit Koyuki from the Self-Reflection Room to support the operation against Hod.
