Noa Yuuki is a mysterious second-year student at Kugata Girls’ Academy, best known as the main heroine of Episode 4 "Snow-Colored, Sakura-Colored, After the Snow" in the 9-nine- visual novel series. With a petite frame, an intense sense of justice, and an unmistakable aura of chuunibyou, Noa stands out among her peers. She is known as the "Parfait Queen" at the café Nine Ball, though she’s completely unaware of the nickname. Noa is feared and admired for her unbreakable moral code, her fierce honesty, her rare moments of cuteness, and her crucial role in the battle against supernatural threats.

Noa is notably petite, standing at only 146cm tall. Her slender build is reflected in her delicate figure. Her fashion sense is described as unique, tending toward the eccentric. She often carries herself with a brisk, straightforward demeanor, and when in the presence of cats, her expressions soften dramatically.
Noa is defined by a powerful sense of justice—she adores righteousness and despises evil.
She is direct and blunt in conversation, often speaking without honorifics or hesitation.
Despite her tough exterior, she is able to admit her own faults without excuses, showing refreshing honesty.
Noa’s chuunibyou (delusions of grandeur with fantasy or hero tropes) is apparent in her dramatic speech and penchant for naming her own abilities.
She is a self-acknowledged introvert who jokingly refers to herself as a “creature of darkness.”
Noa has few friends, partly because she tends to put up her guard in social situations.
She enjoys anime, manga, parfaits, and, above all, cats—though felines rarely approach her.
Her strong spirit allows her to keep calm and composed, even when confronted by unsettling or tragic truths.
Noa attends Kugata Girls' Academy as a second-year student.
She is a regular at the café Nine Ball, where she often enjoys parfaits—gaining her the "Parfait Queen" moniker among friends.
She leads the "Valhalla Society," an organization she founded to pursue justice and fight supernatural foes.
Unlike the protagonists from other schools, she meets the main cast most often at Nine Ball.
Her chuunibyou tendencies and her passion for justice are largely influenced by her past, particularly the loss of her younger sister in a traffic accident.
Noa wields an artifact she named "The Order," a silver ring worn on her left eye.
The artifact’s true power is “judging sinners”—allowing Noa to punish any individual she deems guilty, according to her own sense of justice.
She must follow a three-step internal process before activating The Order, causing a slight delay that can be exploited by speedy foes.
If Noa considers someone innocent, the ability has no effect, but this is both a strength and a weakness: it prevents collateral damage during possession cases.
Her punishments manifest in various forms, such as chains of light or lightning strikes; she can even target and punish parallel versions of a guilty person across timelines.
She’s capable of extraordinary feats of willpower, remaining conscious under mental strain that incapacitates others.
Noa’s closest bonds are with the members of the Valhalla Society, including Kakeru Niimi, Sora Niimi, Miyako Kujou, Haruka Kousaka, and Renya Takamine.
She shares a special kinship with Haruka Kousaka; the two bond over anime, manga, and a mutual love of cats.
Though she is an outsider at first, her willingness to cooperate develops as mutual trust grows, especially after confirming shared goals.
Her past loss of her sister is a driving force in her interactions and her need to uphold justice.
She is unaware of her “Parfait Queen” nickname, but friends enjoy observing her sweet tooth.
Noa develops a deep relationship with Kakeru Niimi in her route, sharing trust and eventually romantic intimacy.
Noa is a cat fanatic, but ironically cats are not drawn to her; she is often seen trying (and failing) to pet strays.
She cannot keep animals at home, which only increases her obsession with cats.
She is highly sensitive to social situations involving parties or friends, often reacting with visible discomfort.
Her cooking and private fashion choices are considered "interesting" by those around her.
Noa dislikes raw tomatoes and sushi.
Her “activating phrase” for The Order is “The Order, Active!,” though this is mostly for style and self-encouragement.
She is known for her unwavering mental stamina in high-pressure situations.
"I’ll say it again...! If you cannot stand back up after seeing him like that, after hearing those words... then you are not worthy of him...!"
"Our memories may disappear... but it’s okay, because... Even if my memory is lost, as long as you are yourself... I will... fall in love with you, again and again."
