Kae Yukiwari

is an exchange student and the princess of the Land of Bamboo.

Background
As the heir to the crown, Kae had been required to act in a manner that befitted her status. Due to that, she did not get a chance to make friends and spend time with them and her younger brother during her childhood. Kae was very close to her late mother. She would often attend parties hosted and prepared by the queen. As Kae voiced her admiration of her mother, she encouraged Kae to make sure she does things her own way, and looked forward to attending a party hosted by Kae.

Personality
Kae is a very cheerful and kind girl. While proper and dignified, she secretly prefers the more carefree life of the commoners, disliking having to meet the expectations people have for royalty. She enjoys reading romance novels and meeting new people. She idolised her mother, hoping to grow up to be like her.

Because of her royalty lifestyle, Kae pushed herself to remain graceful and elegant in front of her classmates, but after Kawaki convinced her to act as herself to not only make herself happier, but also allow her classmates to know the real her, Kae allowed herself to loosen up and become more relaxed around her friends. Because of this stifling, Kae felt a need to reclaim lost experiences, such as playing with friends her own age.

Appearance
Kae is a fair-skinned girl of average height who is considered very pretty. She has blue eyes and grey-blond hair tied in a left-side ponytail with upward curves strands framing the sides of her face and short bangs splitting in the centre of the forehead. She wears white clothing lined with blue on the collars with grey pants and white sandles.

While appearing formally as a princess, she wears a blue, long-sleeved qípáo-like garment with dark blue and light blue linings, two grey necklaces, one of which has a pendant, and a simple necklace-like accessory across her forehead with a small pendant hanging over it.

Abilities
In her efforts to emulate her late-mother, Kae is a talented party planner and host, including personally making tea and cake.

Kawaki & Himawari Academy Arc
Giving her a chance to experience some freedom from her duties as a princess, Kae was sent to Konohagakure, attending their Ninja Academy. Without her knowledge, this was also done to ensure her safety while a threat of assassination was investigated back in the Land of Bamboo. There, she quickly became popular for her beauty and the revelation of her nobility. She found Kawaki interesting, despite him being older than other students and more standoffish. When he tried to befriend her, many confused it with him trying to woo her. Kawaki later caught her acting naturally, and she told him about how people expected her to act. Eiki Fūma, who did have a crush on her and found Kawaki suspicious, attacked him with a summoning scroll, but was knocked out by the summon. Kawaki protected Kae from the summon. Kae asked him who he was, but he brushed it off, just saying he wanted to befriend her, and offered her a romance novel. She later told Batora Kuromori how she was enjoying her time in the Academy.

Later, eager to make friends, Kae invited her class to a tea party. Determined to succeed, Kae even baked a cake herself, trying to live up to her mother's memory. During the party, she and Himawari bonded over having leaders for fathers. When her cake was served, Kawaki caused a commotion by rushing to stop from eating it, believing it to be poisoned. She stopped him and Eiki from fighting and asked whey Kawaki did it. Unable to reveal his mission, he merely excused himself. Osuka teased her for her failed party, but Kawaki and Himawari exposed her as the culprit, having discovered she forced Neon into injecting mustard into the cake as a prank with her drone. When Osuka denied any involvement and tried to pin everything on Neon, Kae lost her composure and scolded her for abusing her friend. She tried to recompose herself, but her friends enjoyed her genuine attitude. At Kawaki's suggestion, she continued the party, and enjoyed the taiyaki he brought.

When Team 7 taught her class as special instructors, an exercise divided most of the class. Kae took neither side, and through the conflict attempted to help reconcile both sides. When their teacher was successful, Kae took part in the picnic and cherry blossom viewing party. Days later, when her class-mates decided to investigate the Academy's Seven Mysteries at night, Kae joined them, but secretly had Batora fake them mysteries so as to maintain her friends' sense of wonder, and convinced Kawaki to help Batora. When one of the mysteries was seemingly real, she felt guilty over faking them, but later discovered it was just Shino's insects cleaning the Academy. She was delighted that her involvement cemented a new story as part of the Seven Mysteries.
