Set in a futuristic Japan where anime and manga characters ("mangas") and people co-exist, Rakki Fukuda is an aspiring young manga girl who dreams of becoming a famous and heroic mech hero named Mechagirl to fight against villains just like what her father used to do. But upon arriving at the Sugoi Corporation in Manga City where mangas get approved for their talents, she nearly gets rejected by its dangerous CEO Akira Sugoi, who does not want to let juvenile wannabes become popular and thinks they are not good enough to become heroes. Rakki, along with her best friend Fumiko Suzuki, bands together a group of other mangas in Manga City by forming an alliance to help her achieve her goal.
