Sakura-chan is a minor character from the series, best known for her cherry blossom theme. Her design leans pretty hard into the aesthetic—her hair mimics the tree's leaves, and she's got matching leaf motifs adorning her head and incorporated into her skirt. She rounds out the look with a white collar and a pair of fairy wings.
She first showed up in the episode "Anpanman and Sakura-chan" and has made scattered appearances since then. Fans mainly associate her with springtime, and she's remained a supporting character rather than a major player in the story.
