Yoshino Himekawa (氷芽川 四糸乃, Himekawa Yoshino) is the second Spirit saved by Shido. She always carries a hand puppet named Yoshinon (よしのん, Yoshinon), which she values as her hero.
When Yoshino first appeared in the series, she encountered Shido. To him, Yoshino seemed to be a lost child wandering around in the rain. The next time they met, Yoshino fell under attack from the AST and ran away. During the third time, Shido made the decision to save Yoshino from herself and the AST. This decision was because he discovered that Yoshino was an incredibly kind child who didn’t want to hurt even the people who were attacking her.
