Shizuku has light blue eyes with long eyelashes and short light blue hair, worn loose and wavy, which covers her left. She has a beauty mark near the right corner of her lip. Her voice is light and airy. Shizuki, initially calm and poised, has quirks like putting miso soup in her thermos and being tech-challenged. As she evolves as an idol, she prioritizes authenticity over a perfect image. Additionally, she's a bit air-headed, enjoying walks but struggling to recall street names.
