Description
Itsuki Myōdōin, known as Cure Sunshine, is a 14-year-old student at the private Myōdōin Academy and serves as the student council president. At first glance, she appears to be a handsome and princely young man, admired by her female classmates for her athleticism, sharp intellect, and composed demeanor. However, this masculine presentation is a role she has chosen to adopt. Itsuki is actually a girl who has been cross-dressing to fulfill the duties of the heir to the Myōdōin family and its martial arts dojo, a responsibility originally meant for her older brother, Satsuki, who has been bedridden due to a long illness. This family obligation forced her to suppress her personal desires for an extended period.

Despite her cool and capable exterior, Itsuki has a deep love for cute and feminine things, including dresses and stuffed animals. She begins to reconnect with this part of herself after being invited to join the school's fashion club, where she gradually feels more comfortable expressing her true likes and feelings. Her internal conflict is central to her character; she is torn between her sense of duty as the family heir and her own identity as a girl who enjoys traditionally cute things. Her primary motivation for becoming a Pretty Cure is a powerful desire to protect her beloved older brother, Satsuki. When his heart flower wilts due to fear and anxiety, Itsuki resolves to fight, channeling her light to dispel the darkness from his heart.

In the story, Itsuki is the third member to join the team of Pretty Cures, making her debut as Cure Sunshine in episode 23. Her partner is the fairy Potpourri, a newborn精灵 who sought out a suitable companion. Within the group, Itsuki serves as a unique blend of defender and close-range combatant. Unlike many previous yellow Cures who relied heavily on their powers, she is recognized as the only member with genuine martial arts training, allowing her to balance powerful defensive abilities with aggressive physical combat experience. Her key relationships include her brother, Satsuki, who she feels a strong need to protect, and her fellow Cures: the shy Tsubomi (Cure Blossom), the energetic Erika (Cure Marine), and the experienced Yuri (Cure Moonlight). Tsubomi initially develops a crush on the boyish Itsuki before learning she is a girl.

Throughout the series, Itsuki undergoes significant personal development. She starts as someone who feels she must sacrifice her own identity for her family's sake but gradually learns to accept herself. By the end, she successfully reconciles her strength as a martial artist with her love for cute things, becoming a girl who can express both without shame. Her character arc culminates in self-acceptance and the realization that she does not need to hide who she truly is to be a reliable and powerful individual.

As Cure Sunshine, her theme is the sun and her symbol is the sunflower. Her abilities are primarily defensive but versatile. Her signature defensive move is the Sunflower Aegis, a large, sunflower-shaped shield that can block and even deflect enemy attacks. She can also create a spherical barrier around herself called Sunflower Protection. For offensive maneuvers, she possesses Sunshine Flash, which fires countless light bullets, and Sunshine Dynamite, which releases explosive energy from her body. Her primary finishing attack, used with her transformation item, the Shiny Tambourine, is Pretty Cure Gold Forte Burst. This technique involves gathering power, causing flowers of light to swarm and bind the enemy before a massive sunflower appears to purify them.
