Cure Happy has the power of Holy Light, which enables her to fire beams, create bursts of light around herself, and enhances her leaping capabilities.

Hoshizora Miyuki (星空 みゆき, Hoshizora Miyuki) is one of the five main Cures in Smile Pretty Cure! and she's the group leader. She attends Nanairogaoka Middle School in Nanairogaoka Class 2-2 along with the other Cures.

Miyuki's alter ego is Cure Happy (キュアハッピー, Cure Happy)? She controls the power of Holy Light.

Miyuki has light skin and magenta hair styled in cone-shaped buns tied with yellow bows. Her bangs and forelocks frame her face, and she has a curled cowlick. Miyuki's eyes are magenta. She wears a pale pink long-sleeved shirt beneath a pale yellow and fuchsia vest, a layered pale pink and magenta mini skirt, white tights with pink stripes, and pink sneakers with white accents. During summer, she switches to a ruffled short-sleeved pink shirt with a magenta ribbon on the chest, pale blue denim capris, and fuchsia sandals with ankle straps.

As Cure Happy, her eyes become lighter with hair reaching knee tied in low pigtails with a large curled strand of hair on each side of the head. She gains a white tiara with a dark pink gem and chibi wings to match her earrings. She wears a dark pink choker. Her short, light pink dress has dark pink detail and pearl pink ruffled trim. The sleeves have a feathered white layer with two, dark pink spheres on top, and on the chest is a magenta bow with a gold medallion in the middle. A pair of short tails hang from the back of the skirt. She also gets white and light pink boots, fuchsia shorts, as well as white and magenta wrist pieces.

Miyuki is a bright, kind-hearted, and energetic girl who loves fairytales. She is always happy and optimistic but seems occasionally naive. Miyuki is also really clumsy to the point where she sometimes ends up hurting herself when she gets overly excited, such as hitting her head after falling back. Multiple running gags in the series include Miyuki falling flat on her face after she randomly trips and her always getting hit in the face by random objects such as Candy and Pop's storybook.

During her childhood, Miyuki was a quiet and timid girl who was too afraid to interact with others. She would often read storybooks to console herself until Tae, her grandmother, gave her a mirror necklace and told her to always put a smile on her face in front of it. An encounter with a mysterious girl results in her becoming who she is now. Despite being normally cheerful, she still shows notable signs of nervousness such as her class introduction, being on stage for the fashion concert, and finding the Akanbe frightening in her first battle. However, Miyuki gains confidence in her abilities and develops courage over time. Her enthusiasm, motivation, and determination often help her to lead the other Cures in battle.

As she loves fairytales, her favorite childhood is reading storybooks. Miyuki loves them because the happy endings to these stories always leave a warm and happy feeling inside her heart, which she summarizes as a feeling of being "ultra happy!", making her cherish happiness and smiles in high regard. She hates seeing others being sad or crying and does her best to cheer them up when they do. Miyuki eventually realizes what her own happiness is and wishes to share that kindness and feeling with others.
