Hinata Sakurazaka is one half of the twin duo known as Team Sakura, alongside her younger identical sister, Manabi. Their act is built upon the extraordinary synchronization they achieve as twins, a skill that brings them to the attention of an underground dance competition called Dance Road. Hinata is the more reserved and feminine of the two sisters. Her personality is subtly defined by her unique verbal tic: she often describes her moods and situations using the English words happy and unhappy. When she declares things to be unhappy, she can become remarkably formidable, even surpassing her sister in intensity.

Hinata comes from an exceptionally wealthy family, a background that affords her and her sister a life of luxury that includes the services of a loyal butler. Despite their privileged lives, their primary passion is dancing, which has driven them to travel the world extensively to seek out and meet their favorite performers in person. Among all the talented dancers they have encountered, they become particularly captivated by Otosaki Kanon, a member of the series' central dance crew, Tribe Cool Crew. This keen interest in Kanon serves as a primary motivation, drawing Team Sakura into the story's orbit.

Her key relationship is, without a doubt, with her twin sister Manabi. Their bond as twins is the very foundation of their identity as dancers, and their telepathically synchronized movements are their greatest strength. Regarding her role in the story, Hinata, as part of Team Sakura, serves as a rival and later an ally to the main characters, her path crossing with theirs due to her admiration for Kanon and her participation in the Dance Road competition. There is no information available regarding her development throughout the series or any notable individual abilities beyond her synchronized dancing with her twin sister.
