Shizuku has a kind and mature personality. She worries a lot about disappointing her fans, feeling she must maintain a "perfect" image, but after the event My Color! she begins to show her authentic self on livestreams. While she appears very calm and poised, she does have some quirks, such as putting miso soup in her thermos and being extremely bad with technology. As she grows as an idol, she becomes determined to stay true to herself, not the perfect image she had before.
