Myoudouin Itsuki (明堂院 いつき Myoudouin Itsuki?) is the student council president at the Myoudou Academy Junior High School. She is the granddaughter of Myoudouin Gentarou, the president of Myoudou Academy. Because she looks and dresses like a male, she is often mistaken as one by new students, and even people who know about her situation state that sometimes they forget that she is a girl. She cross-dresses because she chose to take the place of her older brother, Satsuki, who is too sick to act as the heir of the family dojo. Her Heart Flower is the peony, symbolizing her rebirth as a person and her noble background. Itsuki's Cure ego is Cure Sunshine (キュアサンシャイン Kyua Sanshain?) and her catchphrase is "I will heal the darkness in your heart with my light!" (その心の闇、私の光で照らしてみせる! Sono kokoro no yami, watashi no hikari de tera shitemiseru!?).



After school, Itsuki visits Tsubomi and Erika's classroom, wanting Erika's fashion club list of members and giving a warning of disbanding the club. When the girls go to give Itsuki the members list for the fashion club, they find her training with the other students at the family dojo. Itsuki takes a break to talk to Erika and Tsubomi, and tells them she will allow the fashion club to remain. Then a student comes with tea for Itsuki and calls her "Lady", much to Tsubomi's surprise. Erika and Itsuki then proceed to explain to Tsubomi that due to a certain situation, Itsuki has to dress and act as a male, which shatters Tsubomi's crush on her.

She later receives a plush bunny from an admirer. She walks off and hides the doll behind a bronze statue, as she does not want anybody to see her feminine side. Cobraja, however, sees her with her wilted Heart Flower, and approaches her. He damages the doll and steals Itsuki's Heart Flower, creating a Desertrian out of a bronze statue. The Desertrian turns people to stone with its eyes, but in the end starts admiring the female school uniform and Cure Marine's clothes, informing Cobraja, who thought she was a boy, that she is female, shocking him. When the Desert Messenger insults her gender, Itsuki's Desertrian kicks him away, and Cure Blossom appears, now understanding how Itsuki really feels about her situation. She then purifies Itsuki's Heart Flower and asks her to join the fashion club afterwards, as a way to feel more feminine. Itsuki says she will think about it, and walks off with the fixed bunny and some male friends of her's from the student council.HPC07

Acceptance of Martial Arts and Girl Things

Still thinking about Tsubomi's offer to join the fashion club, Itsuki walks past Fairy Drop and spots a cute dress. Erika and Tsubomi talk to her shortly about joining the club, but she is still unsure. They advise her to at least try to design something she would like to make. And so having this in mind before training, she draws a dress and gives it to the fashion club the day afterward. The members of the club are impressed by her design, and asks her to follow them to the shop to find fabric for it. Itsuki is still in a dilemma over whether to try do to girly things or to maintain an image as a boy, but Erika and Tsubomi encourage her to finish the dress the day afterward at her home. She tries it on, and Satsuki sees it and states that it looks cute on her, though she is embarrassed and states that she is just fooling around. After a boy named Hiroto is targeted by Kumojaki, she briefly admires Cure Blossom and Cure Marine, before realizing the more important matter at hand. As Itsuki fights Kumojaki, she realizes what judo really means: to protect others. Itsuki joins the fashion club afterwards.HPC15

Becoming Cure Sunshine

When Kumojacky strikes and steals Mizushima Aya's Heart Flower during a storm, Itsuki orders the students to protect the curtain. She is present for watching Pretty Cure battle against a Desertrian. After the battle, Itsuki goes up to Potpourri (who is posing as a stuffed toy) and hugs her, saying that the plushie is cute. Unknown to her, Potpourri feels a warmth come into her because of her touch, making she think that she is the third Cure.HPC22 She plays with Potpourri a little before Tsubomi and Erika close up to them, telling that it is their doll. When Itsuki asks where they bought it, however, Erika says that she made it, convincing Itsuki to give it back.

The next day, Satsuki learns of a surgery that can cure his illness, which makes everyone in the family happy, though Itsuki notes that something is wrong with her older brother.

Frustrated, Itsuki meets the girls again, not knowing that they had been stalking her the whole way because of Potpourri's claims that she is Pretty Cure. They reveal that they heard of the story from her mother, and she confesses her worry for Satsuki, making the girls forget to ask her if she has dreamed of the Tree of Hearts and Cure Moonlight.

Potpourri reveals to Itsuki that she is the third Cure that can transform and fight to protect the Tree of Hearts. However, despite liking the Pretty Cure clothes, Itsuki rejects Potpourri's offer, stating that she doubts she can protect anyone. Right then, Tsubomi and Erika arrive with a bunch of sunflowers, and Potpourri hides inside Itsuki's shirt, making her look pregnant. When they open Satsuki's door, they see that the window is broken, the bed is empty, and the other half of a Heart Flower falls on the floor, revealing Satsuki. They see a wheelchair-Desertrian cause havoc outside the hospital, and Itsuki witnesses Tsubomi and Erika transform into Pretty Cure, revealing their identities. She soon understands that the Desertrian is Satsuki when it starts talking about its fear for surgeries, but even when she tries to wake him up, it only makes the monster hit her.

She is stunned, but when Potpourri tells her to find a name, she sees the sun's shine and fights shortly with the Desertrian before claiming that her name is Cure Sunshine.HPC23 She fights off the Desertrian using Gold Forte Burst, and together with Tsubomi and Erika go to the Tree of Hearts to see it. There, she reveals her dream about the tree and Cure Moonlight, and meet Dark Cure in person for the first time. She manages to defend herself before finding a strategy to occupy Dark Cure long enough for her and Potpourri to recreate the barrier around the tree, making it disappear. They are transported back to Kibougahana, and after the surgery, she is with her mother and grandfather to greet Satsuki, relieved that he made it okay.HPC24

Itsuki in her civilian appearance has brown hair cut into a short boyish style with the tips fanning out a bit with straight bangs, and has brown eyes. In school she wears the boys uniform instead of the girls uniform in order to conceal her real gender. In later episodes she does wear the girls uniform and has allowed her hair to grow out. Her casual clothes consist of a yellow dress with orange trim and a pictures of an orange bow on it, dark blue leggings and white tennis shoes.

As Cure Sunshine, her hair turns yellow and changes length drastically and is pulled into two twin tails tied with orange ribbons and orange blossoms attached, and her eyes also changed to a yellow color.

Her boots reach up to under her knees and are trimmed in orange with ribbons lacing up in the front and forming bows in the back.

Itsuki is gentle, civilized, and very caring for her friends. She is also shown to be somewhat girly, as she finds many toys to be cute and has fashion desires, though she hid them at the beginning. Every time she see's Potpourri showing cuteness, she goes (insanely!) girly and forgets to be calm. Speaking of which, she is usually calmer than Tsubomi and Erika, but nevertheless dislikes seeing her friends suffering or in pain. Like Tsubomi, she has a more calm and caring personality; Erika's lively and care-free manner contrasts sharply with both of them. Itsuki appears to be a gentle, handsome, and athletic girl with a princely demeanor who attacked many subordinates and fans. At the beginning, Tsubomi developed a temporary admiration for Itsuki until discovering her female gender.

And when they were going to the Tree of Hearts by flying and Tsubomi was afraid of heights, Itsuki held her hand and gave her courage to not be afraid of flying. Later on they seem to become best friends.

Kurumi Erika - She respects Itsuki as the president of Student Council and good terms on each other. Itsuki is a kind person that she let Erika continue on the Fashion Club even though she was late and soon Erika recruited her to join the Fashion Club. Ever since Itsuki join the club and became the third Precure, they been good friends and great teamates.
