In Okayama Prefecture, there is a minor underground idol group called ‘ChamJam’. Among them is the shy and introverted member, ‘Maina’, who is at the bottom of the popularity rankings. However, there is an enthusiastic fan who dedicates their entire life to supporting ‘Maina’. This fan, who devotes all their income to Maina, always wears the red gym uniform they used to wear in high school. So much in love that they famously burst a nosebleed during a live performance… the legendary lady ‘Eripiyo’! Until the day Maina stands on the Budokan stage… Eripiyo's idol otaku activities, fueled by all her strength and soul, will continue ♥♥♥ This is the highly anticipated latest work by Auri Hirao, the creator of ‘How to Draw Manga’!!!
