楠木 秋桜香

The protagonist's younger sister, who will be entering a higher grade next year. She's quiet and shy around strangers. Since childhood, she's been completely devoted to her big brother, always trailing behind him, hiding in his shadow. She shows the protagonist how adorably she's grown, but both her heart and body are still too immature to be called a “woman.” Having always relied entirely on the protagonist and having few friends, she's also a bit more emotionally immature compared to other girls her age. She has waited endlessly for her brother, who vanished suddenly and inexplicably from her life. Her affection for him is blind; he has always been the most important person in the world to her. She carries a stuffed cat toy given to her by her brother long ago, never letting it out of her sight. Its name is “Chocolat-nya.” Her fee for giving her father a shoulder massage is 20 yen per session. [From Official website]
