Role in the Series
Miyuki is a bright and energetic girl who loves fairy tales. She is always happy and optimistic, making her seem very naive. Simple things such as eating cake can make her happy, and she is fond of using the phrase "Ultra happy!" to show her joy. In contrast, when things do not go her way, she shows her disappointment by saying "Ha~ppu~ppu". However, Miyuki stated she was a very timid and shy girl who is not good with others in the past until Tae, her grandmother gave her a mirror to tell her always put a smile on her face and an encounter with an mysterious girl will result in her becoming who she is now.
She is also extremely unreserved, openly asking Akane and Yayoi to become Pretty Cure with her, and hugging and jumping on Akane/Cure Sunny despite knowing her for only a day. She often openly proclaims her love for her friends, announcing that she really likes Reika in Episode 5 and Candy in Episode 6.
Miyuki likes to play-pretend and was thus extremely excited to become a Pretty Cure, proclaiming her Cure costume as "cute" and that being a Cure is like "being a superhero on TV". SmPC01 Despite this, she has little confidence in her own powers as Pretty Cure at first, calling the Akanbe monsters "frightening" and preferring to run away instead of fight. However, she gains confidence in her abilities over time, and though she does not come off as a very reliable leader, her enthusiasm often helps her to lead the other Cures in battle.
Miyuki often gets overexcited over small things and ends up hurting herself in the process. In one instance, she got so excited when she learnt that there were 5 Cures in total that she fell backwards and hit her head. SmPC02Another time, she was so amazed at all the fairy tales in the Magical Library that she tripped over a book and fell flat on her face. SmPC06 She is shown to be bad at sports, prone to catching balls with her face and falling flat on the ground. A running gag in the series is how Miyuki always gets hit in the face by random objects. Thus far, she has been hit by Candy, a volleyball, a soccer ball, Pop's storybook and the "turning ti~ny" mallet. This clumsiness extends to her Cure form as well, when she failed to aim her finishing attack at an Akanbe and hence missed it totally. SmPC02
As she loves fairy tales, Miyuki's favorite pastime is reading storybooks. During her self-introduction in class, she explained that she loves reading fairy tales because the happy endings always leave a warm and happy feeling inside her heart, which she summarizes as a feeling of being "ultra happy!". The most important thing to Miyuki is to be happy and to smile. She hates seeing others cry and does her best to cheer them up. In Episode 2, despite being defeated by an Akanbe, she insisted on smiling, saying that she won't cry or "happiness will be gone". SmPC02
Due to her love of reading picture books, she seems to know most of her fairy tales well. The first time she faced up against Wolfurun, she hid behind a brick wall, naively telling him that à la The Three Little Pigs story, he would not be able to get her. However, her strategy failed when Wolfurun created an Akanbe out of the brick house. SmPC01
