Also known as: 水谷絵理
One of the main characters of the Idolmaster series, introduced in the DS game The Idolm@ster: Dearly Stars.
A shy 15-year-old idol from 876 Production. Eri was a Hikikomori and net idol under the name "ELLIE", scouted by 876 and turned into an idol - a prospect the otherwise introverted Eri is not too thrilled about.
Eri's theme color is robin's egg blue, and is voiced by Hanazawa Kana. She tends to use '?' at the end of her words.
