Oshi ga Budoukan Ittekuretara Shinu

After seeing Maina Ichii, a member of the idol group ChamJam, perform at a nearby event and after receiving a flyer from her, Eripiyo falls in love with the shy and guarded rising star and resolves to dedicate her life to helping her. Eripiyo quickly gains fame as Maina's one and only unequaled admirer due to her magnetic personality and famous red tracksuit. Eripiyo is always there at every event Maina attends, whether it's a performance or a tiny fan event in the middle of nowhere. Eripiyo is determined to fulfill her ambition of attending her idol's performance at the renowned Budoukan stadium, despite suffering an injury or Maina's seeming lack of interest in her.
