Nanase Yui

Yui is recognizable by her long, dark blue-black hair usually worn in braids.

She always wears distinctive half-rim glasses.

In her daily clothes, she prefers outfits with yellow as the base color and a light blue outerwear.

She sometimes accessorizes with a yellow beret, especially seen in colder months.

When she removes her glasses, her eyes are humorously depicted as simple, rounded "threes," reminiscent of classic anime gags—a nod to her extremely poor eyesight.

Calm, kind, and somewhat reserved, Yui is never shy to help those around her.

She warmly accepts even Haruka's wildest dreams, always offering encouragement and sensible advice.

As Haruka’s roommate, Yui often acts as a gentle voice of reason, providing soft but necessary "reality checks" and support.

Despite having no magical powers, she never hesitates to stand up bravely, even against enemies like Close and the Zetsuborgs.

Yui is a first-year student at Noble Academy, living in the school dormitory.

She is Haruka’s roommate and quickly became her best friend after helping her adjust to school life.

Her dream is to become a picture book author.

She adores stories and illustrates daily events in her sketchbook.

Although an ordinary human without combat abilities, she plays a crucial supporting role for the Pretty Cures.

Yui has no magical combat abilities, but her belief in her dream is her greatest strength.

More than once, her pure determination has allowed her to resist and even break free from the despair traps set by enemies.

Her unwavering optimism generates subtle but vital energy; she even manifested a Dress-Up Key through the strength of her wish, aiding Cure Scarlet’s power-up.

She excels at supporting others, coordinating evacuations during monster attacks, and recording the Cures' secret struggles in her illustrated diary.

Her emotional resilience is remarkable—she is the only person in the series to be used as a Zetsuborg host multiple times, each time gaining strength to resist despair.

Haruno Haruka: Yui’s closest friend and roommate; she steadfastly supports Haruka’s “princess dream.”

Kirara Amanogawa, Kaido Minami, and Akagi Towa: Calls them with affectionate "chan" (for Haruka, Kirara, Towa, Pafu), "san" (for Minami, Prince Kanata), and "kun" (for Aroma, Kuroro).

Aroma and Pafu: Treats them as valued friends, addresses them warmly.

The Pretty Cures: She is the only human (non-magical) peer who knows their secret and actively chooses to support them.

Mochizuki Yume: Her favorite picture book author and a major inspiration.

Prince Kanata and the Fairy Companions: Recognizes them respectfully and is trusted with vital secrets.

Yui is unique in the series for being imprisoned by enemies four times and used as the host for despair monsters—an all-time record in Pretty Cure.

In early episodes, fans speculated she might become a Pretty Cure due to her prominent supporting role and magical happenings around her.

She refers to herself simply as “watashi” and is humble about her contributions, sometimes feeling left behind but ultimately finds her place.

Although her role seems "plain" compared to previous male supporting characters, her presence bridges the everyday world and magical conflicts.

Her love for storytelling translates into a dream to one day create and publish picture books, eventually chronicling the hidden heroics of the Pretty Cures.

“We can’t all be magical, but we can all have dreams.”

“I want to share everyone’s story, so nobody ever feels alone in their fight.”

“I’m happy just being here—watching over all your dreams.”

“No matter how many times I’m trapped, my dream gives me strength.”

“Even if I can't fight like a Pretty Cure, I can draw a story no one else can.”

Introduction & Early Friendship

Yui meets Haruka on their first day at Noble Academy.

She immediately becomes her roommate and helps her navigate the school's challenges, supporting Haruka’s “princess” ambitions.

Her own dream—to be a picture book author—is revealed and targeted by Close in the first episode, causing Yui to be turned into a Zetsuborg.

After being rescued by Haruka/Cure Flora, Yui regains her confidence and continues to support her friends.

Becoming an Ally

Yui gradually becomes aware of mysterious events surrounding her friends.

Unable to stand on the sidelines, and after witnessing Princess Pretty Cure transformations, she is swept into their world and resolves to be their supporter.

She participates by keeping their secret, helping ordinary students evacuate during monster attacks, and offering encouragement during tough battles.

The Weight of 'Ordinary'

Despite feeling somewhat left out when the magical girls go on missions she can't join, Yui grapples with her own limitations as a non-magical person.

She chafes at being excluded for her own safety, but never resents her friends.

Her biggest emotional trial comes when her artistic dream is manipulated to trap her in despair, but she always breaks free with her own resolve.

Ultimate Contribution

Yui’s sketches and witness of the Pretty Cure battles help create a vital Dress-Up Key, providing a power-up for Cure Scarlet.

When all of Noble Academy is entrapped during the final battle, Yui’s indomitable heart enables her not only to break her own despair prison but to inspire others to do the same—weakening the enemy and turning the tide.

Her encouragement creates “the key of hope,” which opens the way for the Pretty Cures to unlock their Grand Princess forms.

Fulfillment of Her Dream

As peace returns, Yui is seen determined to fulfill her dream and chronicle the Pretty Cure’s secret story for everyone.

The final episode flashes years into the future, where a young girl is inspired by Yui’s published picture book “Princess and the Key of Dreams,” showing that her dream has become reality.

Yui often serves as comic relief, especially with her three-eyed gag when removing her glasses.

Although not always invited to every adventure, her absence is regularly noticed, testifying to her importance.

She is voiced by Haruka Yoshimura, an avowed Pretty Cure fan, making the casting especially meaningful.

While she never becomes a magical girl herself, fan art and speculation about "Cure Diana" are widespread and beloved in the fandom.

Yui is considered the “princess of support” for the series, embodying the power of an ordinary person’s unwavering dream.
