The narrative is set in a future version of Akihabara. Once known as the "Holy land of otaku," it has since transformed into an office district. Otaku culture is in decline, people are forgetting anime and manga, and only a handful of specialty stores remain in business. The world of creative works relies on the "memories" of manga and anime held in people's minds. However, when a virus destroys a creative work's world, it vanishes from everyone's memory and is erased from the material world. Twelve girls employed at a small shop tucked away in a corner of Akihabara are battling the virus to safeguard everyone's cherished memories of their favorite manga and anime, aiming to restore Akihabara to its former state!
