|Voice Actress||Aina Kusuda|
Eiko is one of the original characters of the series. She is a supporting character who can usually be seen in Laala's concerts and claims to be her biggest fan. Though it has yet to be confirmed, her candy hair accessory has led fans to assume that she is a Pop-type idol using Candy Alamode.
Eiko has short red hair that curls slightly at the shoulders. She has green eyes. She also wears a yellow and white striped candy barrette on the left side of her head. Like most of the cast, her PriPara appearance is identical to her normal appearance. Her school uniform consists of a pale blue shirt with a white collar, navy blue bow, and white skirt. When she plays tennis, her hair is up in a ponytail, and she wears an orange skirt and white top.
Eiko is a kind and slightly emotional girl who can become easily attached towards others and befriend them; even going as far as claiming herself to be Laala's number one fan shortly after her debut. She can be easily discouraged though, such as when she first played a tennis match against Love.
