Description
Chisa Shiraishi, affiliated with Hoshimi Production, is the younger sister of Saki Shiraishi. While Saki belongs to Tsuki no Tempest, Chisa is part of the idol unit Sunny Peace. Her light pink image color (#e0a4d4) complements her sand brown hair and violet eyes. Standing 147 cm tall and weighing 39 kg with measurements of B76-W58-H78, she wears a navy blue and white dress featuring pink accents, laces, and a cloth attachment. Her ensemble includes a pink and white hair ornament, navy blue stockings with frills, pink high-heel shoes, and a star, sun, and moon anklet on her right leg.

Timid and introverted, Chisa frequently hides behind Saki due to a history of reliance stemming from their upbringing. With their parents working, Saki assumed caretaking responsibilities. Chisa auditioned for Hoshimi Production primarily to stay close to her sister, though an initial rejection caused disappointment. An unexpected acceptance call followed, which she initially suspected was a hoax. Her idol activities aim to overcome shyness and personal complexes.

Separation into different units challenges Chisa's dependence, compelling her to interact with other members. During rigorous training for the debut song "Shine Purity," she nearly quit, struggling with feelings of inadequacy and guilt over requiring extensive support. Encouragement from Saki and fellow idols—especially confidante Shizuku Hyodo, whose talks foster positivity—helped her persevere. Chisa views Hoshimi Production members as "family" and aspires to become a top idol to inspire others facing insecurities.

Her skills include knitting and clothing design; she often selects Saki's outfits to prevent repetitive choices like printed T-shirts. She frequents Hoshimi City handicraft stores for fabrics. On days off, she shops with Saki or watches horror films alone, relating to characters confronting adversity. She favors sweet foods such as milk crepes and pancakes prepared by unit-mate Haruko Saeki. At school, she prefers home economics for cooking and sewing but dislikes physical education, particularly ball games. Her mornings begin with Saki waking her, and during dorm cooking duties, she prepares salads, yogurt, bread, and fried eggs.

Saki remains foundational to Chisa's life; they spend roughly 90% of free time together cooking, watching movies, or shopping. A childhood memory of being lost and comforted by Saki's hug underscores their bond. Fan interactions evolved from fearing loud voices to appreciating kindness after direct conversations. Musically, Chisa values "Shine Purity" as an emblem of "trust" and unity, resonating with the lyric "Sometimes, the dream never ends. The one who taught me that, was you." She balances enjoyment and nervousness during live performances, seeing them as opportunities to uplift hesitant individuals like herself.
