The manga revolves around Suuko, 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 Itrio and tries to make them sell more, but she is impeded by the charismatic otaku Ryu-san and the underground idol Mariko.
