The original manga revolves around Sūko, an idol-loving hikikomori (shut-in) who has one ability: To make any idol popular through the power of blogging. She puts her sights on the Fukuoka idol Itorio and tries to make her sell more, but she is impeded by the charismatic idol Ryūsan and the underground idol Mariko. The author of the manga is an idol otaku herself.
