Description
Lisa Shirakaba is a Starlight School student and idol specializing in the sexy type, primarily affiliated with the Dolly Devil brand. Her surname, meaning "white birch," reflects her Hokkaido origins and the region's white birch forests. Her given name Risa (often localized as Lisa) carries Hebrew origins meaning "devoted to God."

She possesses long, straight black hair with slightly wavy-tipped bangs and lavender eyes, consistently wearing a purple ribbon or frilly headband. Her height is 160cm. Born on December 14th, she is a Sagittarius with blood type A.

Her personality is calm, rational, and level-headed, displaying maturity beyond her years and a tendency for deep analysis. Her mother and closest friend note she rarely exhibits intense passion for most subjects. However, genuine inspiration, particularly concerning idol activities, ignites visible determination and passion. Despite her composed and adult-like demeanor, she becomes easily embarrassed if perceived as childish, especially around new people.

Her background centers on a lifelong friendship with Nono Daichi. Lisa frequently assisted Nono's family with farm work and consistently watched over Nono. Her idol ambition sparked after attending a Luminas concert during their Hokkaido tour. Witnessing this passion inspired Nono to join her. Together, they passed Starlight School's entrance audition without wearing the standard uniform and performed a Special Appeal, becoming the second known idols to do so after Ichigo Hoshimiya.

Her relationship with Nono Daichi remains central. They share the Dolly Devil brand preference and embarked on their idol journeys simultaneously, supporting each other closely. Nono's family affectionately nicknames her "Lisappe" (リサっぺ). Her parents are Shizuo Shirakaba (father) and Reiko Shirakaba (mother), the latter a piano teacher.

Her favorite foods are potato salad and milk. She excels academically and is adept at knitting. Within the mobile game universe, she and Nono form the unit "Nori Nori Sisters."

She is the only known Sagittarius idol in the franchise not specializing in the pop type. She admires Mizuki Kanzaki and shares similarities with her. Her singing voice is shared with Rin Kurosawa, Tsubasa Kisaragi, Lily Shirogane, and Koharu Nanakura. She and Nono were the first idols to concurrently share a preferred brand with another main character.
