Shizuka Sakaki decided to pursue a career in voice acting while still a student at Kaminoyama High School, even before joining the school’s animation club. Initially, she declined Aoi Miyamori’s invitation to join the club, doubting Aoi’s commitment. However, after seeing Ema Yasuhara’s artwork, Shizuka came to trust their shared passion and ultimately joined the group.

Following graduation, Shizuka began her journey as a professional voice actress. To support herself financially, she took on part-time work as a waitress at Matsutei, a traditional Japanese bar. Despite her determination, Shizuka’s career faced significant struggles, with long periods of inactivity and repeated failures to secure major roles.

During the production of Third Aerial Girls Squad, Shizuka auditioned for the role of Catherine but was not selected. The ongoing rejections began to weigh heavily on her, leading to moments of doubt and discouragement. However, her persistence paid off when she was later cast as Lucy, Catherine’s younger sister, a small but meaningful step in her career.

Shizuka is also friends with Mari Tateo, a fellow member of the talent agency Aka Oni Productions. Mari often serves as a confidante during Shizuka’s professional struggles.

In the SHIROBAKO movie timeline, Shizuka transitions into a new role as a reporter covering voice acting news. She resigns from her part-time job at Matsutei, but remains affiliated with Aka Oni Productions.

Shizuka Sakaki has long, wavy red hair that reaches her hips, typically styled into a loose, messy bun. She has bright sky blue eyes that complement her vibrant hair color.

Her usual outfit consists of a turquoise jacket worn over a white shirt, paired with a dark pink skirt that reaches her knees. She also wears brown heels along with white socks, completing her stylish yet casual look.

Shizuka Sakaki is characterized by her hardworking nature and steady attitude, even in the face of adversity. Though she often experiences rejection in her pursuit of a voice acting career, she strives to remain optimistic and continue moving forward. Despite her emotional strength, she has a notably low tolerance for alcohol.

Shizuka has dreamed of becoming a professional voice actress since high school and is affiliated with the talent agency Aka Oni Productions. Her commitment to voice acting was apparent even during her school years. In the manga adaptation, she initially declined to join Aoi Miyamori and Ema Yasuhara in the animation club, believing they lacked seriousness. However, after seeing Ema’s dedication through her artwork, Shizuka changed her mind and joined the club, ultimately staying for the sake of their shared dreams.

Shizuka’s surname, Sakaki (坂木), is composed of the kanji saka (坂), meaning “slope,” and ki (木), meaning “tree” or “wood.”
