is a Japanese manga series by Auri Hirao. It has been serialized in Tokuma Shoten's seinen manga magazine Monthly Comic Ryū since the August 2015 issue. An anime television series adaptation by 8bit premiered on January 9, 2020.

Plot
"Eripiyo" is an extreme idol fan. She is wildly enthusiastic about Maina, the shy and lowest-ranking member of the minor underground idol group Cham Jam that performs in Okayama Prefecture. She gets so wrapped up in her love for Maina during a particular performance, that she has a major nosebleed. Eri will continue to give her complete devotion to Maina until the day she can perform at Budōkan (a major performing venue in Tokyo).
