If My Favorite Pop Idol Made It to the Budokan, I Would Die, Volume 9

Forthright and impetuous Eripiyo is the number one stan for Maina, a sidelined member of the underground idol group Cham Jam, lining up for every event and spending a fortune on CDs and fan meetings to support her fave over the years. During a collectible card event, Eripiyo, Kumasa, and Motoi reminisce over how idol fandom has brought them together, even as Kumasa wonders if these halcyon days might be coming to an end. Still, these last few months have been good for Cham Jam— especially Maina, whose popularity has grown by leaps and bounds after going viral.
For Eripiyo, this should be a dream come true. Finally, the rest of the world is recognizing her beloved Maina in all her adorable glory! But fame has it price, and more fans means fewer chances to spend time with her favorite… a bittersweet blessing that Eripiyo accepts as her lot as a fan. But Maina finds that she dearly misses their usual interactions, clinging to things that remind her of Eripiyo even she feels more distant from her than ever. As her first-ever birthday event draws near, Maina wonders… is there anything she can do to bring them together once more?
