Shizuku Hyodo is a 16-year-old student at Hikarigasaki Public High School and a member of the idol group Sunny Peace under Hoshimi Production, represented by the pastel green color #99C89A. She stands 150 cm tall, weighs 40 kg, with measurements of B77-W57-H79, featuring mint-colored hair typically styled in twin bun ponytails and red eyes.

Quiet and preferring the background, Shizuku is often described as a "gloomy idol fan who lurks in the shadows." Yet she transforms into a highly talkative, deeply knowledgeable figure when discussing idols, earning recognition even among seasoned fans and achieving celebrity status within idol communities.

Her reserved nature and low physical stamina initially challenge her idol career. She struggles with dancing, basic training, and expressing emotions like smiling. Difficulties with conversation and emotional expression cause wavering confidence and significant uncertainty early on.

A key support is her bond with fellow Sunny Peace member Chisa Shiraishi, who faces similar struggles. Their mutual encouragement helps Shizuku gradually gain confidence. She diligently works to improve her skills, leveraging her extensive idol knowledge as a strength while acknowledging both singing and dancing remain works in progress.

Her interests include idol-related "wota activities" and the quiet solitude of sea fishing, which she sometimes shares with Chisa. Shizuku deeply values fan interactions, citing her first fan letter as her happiest memory due to her own history as a fan. She aspires to be an idol who encourages others, aiming to give people energy and dreams through her performances.

Her name "Shizuku" (雫) means "drip" or "droplet," while "Hyodo" (兵藤) combines "soldier/warrior" (兵) and "wisteria" (藤).
