The story takes place in the future, the city of Akihabara. It was once called a “Holy land of otaku” but now has become an office town. Otaku culture has declined, people are losing memories of anime and manga, and only a few specialty shops remain open. What supports the world of creative works are “memories” of manga and anime in people’s minds, but when the world of the creative work is destroyed by a virus, it disappears from everyone’s memory and is erased from the material world. 12 girls working in a small shop in a corner of Akihabara are fighting the virus to protect everyone’s important memories about their favorite manga and anime, and return Akihabara to the way it was before!

As Tooru continues on her quest to become the greatest maid and Kanna Kamui fully immerses in her life as an elementary school student, there is not a dull day in the Kobayashi household with mischief being a daily staple. On one such day, however, a massive landslide is spotted on the hill where Kobayashi and Tooru first met—a clear display of a dragon’s might. When none of the dragons they know claim responsibility, the perpetrator herself descends from the skies: Ilulu, the radical Chaos Dragon with monstrous power rivaling that of Tooru. Sickened by Tooru’s involvement with humans, Ilulu resorts to the typical dragon method of resolving conflict—a battle to the death. Despite such behavior, she becomes intrigued by Kobayashi’s ability to befriend dragons and decides instead to observe just what makes Kobayashi so special. With a new troublesome dragon in town, Kobayashi’s eccentric life with a dragon maid is only getting merrier. [Written by MAL Rewrite]
