The Hiiragi Sisters, also known as Green Grass, are both skilled artists and authors who specialize in creating picture books. They are reserved and sweet-natured individuals with a passion for painting. However, they struggle with writing letters and have opted to create Premium Rare Cards for Sakura instead of responding to messages. After meeting Sakura, the sisters gave her a warm embrace.
