Eriko Sakura is a student in Yandere School, and Meisa Ito's best friend.
Eriko is a teenage girl with an average height and build. She has straight, short, carrot-orange hair, only reaching down to her neck, with above the eyebrow bangs. She has a noticeably slim and womanly figure and dark blue eyes. Her face is also rather mature compared to her friend, and especially Akari, though she usually appears sleepy. She has a fair and light complexion that is prone to blushing.
Eriko wears her default school uniform with black stockings and deep brown dress shoes.
Eriko is, according to what is shown of her, a laidback, cheery, and joyful girl who is always seen smiling. Even when being approached by Akari, who she and Meisa appear to dislike, she continues smiling as it seems to be a default facial expression. However, the death of Meisa, most definitely, gave her deep suffering.
