Sakura Yamauchi やまうちさくら is the main deuteragonist in the I Want to Eat Your Pancreas series and the only friend of Haruki Shiga.
Sakura is a young girl with a thin build. She is considered pretty (at least by Haruki). Along with this, her hair color is a light brown with a long bang covering the center of her forehead in between her eyes, with long locks of hair on either side of her face that reaches until her shoulders and curls slightly upward at the ends, with the rest of her hair running down her back. Her eyes are small with her pupils being a light brown or possibly even a dark hazel.

She is often seen wearing her school uniform consisting of a pale beige blazer with dark brown details, a white shirt, a blue bow, and a pleated skirt of the same color paired with long, dark grey socks and brown loafers. At other times, she is seen wearing different plain clothing outside of school.
