Hikaru Jougasaki is a supporting character from the anime Love Love? who is depicted as a fourteen-year-old tomboy. Her appearance includes gray hair that reaches past her hips and brown eyes. She is most often seen in her school uniform, which she wears with a ribbon tie and stockings.

Regarding her background, Hikaru was raised in a household with six older brothers, an upbringing that contributed to her tomboyish personality. Her role in the series is tied to a fictional show within the anime, as she plays the character Sari Yellow Rayer, also known as Priscilla, on a production called Cosprayers. Her motivations and actions are largely centered on the series' script writer, a character named Naoto. Aware of his position, Hikaru makes attempts to seduce him. However, these advances are not born from genuine romantic feelings, as her true orientation is homosexual.

Within the story of Love Love?, Hikaru has a specific relationship with Naoto, viewing him as a target for seduction, though her attempts consistently fail due to a lack of authentic interest. Her role in the narrative is that of a secondary character, interacting with the main cast primarily through her connection to the Cosprayers production and her romantic pursuit of Naoto. Information on her personal development throughout the series or any notable abilities outside of her performance role is not available.
