If My Favorite Pop Idol Made It To The Budokan I Would Die Vol. 4

Eripiyo is a hardcore idol otaku who is a passionate, diehard fan of the underground idol group ChamJam and is a total stan for idol girl Maina Ichii, even though Maina is the least popular member of the group. After seeing Maina perform, she becomes obsessed with supporting her favorite idol in any way she possibly can, often resulting in her spending all of her money on merchandise and singles. Together with her friends and fellow ChamJam fans Kumasa, who supports Reo Igarashi, and Motoi, who supports Sorane Matsuyama, she attends as many of their concerts as she can while working several part-time jobs in the hopes that one day her support will take Maina and the girls of ChamJam all the way to idol stardom and the big stage at the Budokan!
In Vol. 4, ChamJam are performing at the “Okayama Idol Festival” along with idol groups from Hiroshima and Kagawa prefectures, and you can be sure Eripiyo will be cheering on Maina from the crowd! Is this their first step toward the Budokan?
