Shizuku has a kind and mature personality. She worries a lot about disappointing her fans, feeling she must maintain a "perfect" image, but she begins to show her authentic self on livestreams. As she grows as an idol, she becomes determined to stay true to herself, not the perfect image she had before. Shizuku can also be a bit air-headed, as according to her sister Shiho, she loves going on walks but can't remember any of the street names.
