Eri Suzuki is a high school student distinguished by her brown hair and violet eyes. Her inconspicuous and unassuming nature causes her to initially escape Naoki Murakami's notice. Without any direct connection or interaction, she cultivates a secret infatuation with him and regularly observes him from afar. These feelings persist despite her awareness of his existing relationship with Haruka Mizuno, forming a defining aspect of her character. A figure based on the character was manufactured in 2004.
