Description
Saaya Yamabuki, a third-year student at Hanasakigawa Girls' High School, drums for Poppin'Party. She formed a close bond with Kasumi Toyama during their entrance ceremony, sparking a daily lunch tradition. Her family operates Yamabuki Bakery, where she actively assists while juggling school and band duties. As the eldest of three siblings—younger brother Jun and younger sister Sana—she once played in the middle school band CHiSPA but withdrew before a key performance. In the main storyline, this departure stemmed from worries over burdening others during her mother's health crisis; an alternate storyline cites her father's illness as the catalyst. Kasumi's unwavering encouragement and her mother's backing later rekindled Saaya's musical drive, making her Poppin'Party's final recruit.

Kind, empathetic, and diligent, Saaya embodies an "older sister" role in the band through her maturity and calm demeanor. She finds it hard to refuse friends, like when tutoring Hagumi Kitazawa. Her appearance features slanted royal blue eyes, long curly dusty brown hair tied in a high ponytail with a ribbon, spread-out bangs, and shoulder-length curled forelocks. She initially wears pale yellow flowing pants and a frilly white off-the-shoulder top.

Beyond Poppin'Party, Saaya bonds with Tomoe Udagawa over shared sisterly and drummer roles, and with frequent bakery visitor Moca Aoba. She works part-time at live venue RiNG alongside Kasumi and Shūichi Taki.

Saaya collects hair scrunchies as a hobby though she doesn’t wear all. She dislikes raw seafood but savors spaghetti aglio olio e peperoncino and cheese. Her interests include karaoke, watching baseball, romance films, and Cinderella tales. Animals typically avoid, scratch, or bite her during interactions. After the My Design, My Texture event, she embraced photography, often carrying a camera and capturing Poppin'Party's promotional shots.

Her drumming practice incorporates three drumsticks, a technique noted in both main and original narratives. She plays a Pearl Drums 4-Piece Reference Pure set in Antique Gold.
