A certain college girl who's loved books ever since she was a little girl dies in an accident and is reborn in another world she knows nothing about. She is now Myne, the sickly five-year-old daughter of a poor soldier. To make things worse, the world she's been reborn in has a very low literacy rate and books mostly don't exist. She'd have to pay an enormous amount of money to buy one.

Naofumi Iwatani, an uncharismatic Otaku who spends his days on games and manga, suddenly finds himself summoned to a parallel universe! He discovers he is one of four heroes equipped with legendary weapons and tasked with saving the world from its prophesied destruction. As the Shield Hero, the weakest of the heroes, all is not as it seems. Naofumi is soon alone, penniless, and betrayed. With no one to turn to, and nowhere to run, he is left with only his shield. Now, Naofumi must rise to become the legendary Shield Hero and save the world!

Seventeen-year-old Hajime Nagumo is your average, everyday otaku. However, his simple life of pulling all-nighters and sleeping in school is suddenly turned upside down when he, along with the rest of his class, is summoned to a fantasy world! They're treated like heroes and tasked with the duty of saving the human race from utter extinction. But what should have been any otaku's wet dream quickly turns into Hajime's nightmare. While the rest of his class are blessed with godlike powers, Hajime's job, Synergist, only has a single transmutation skill.

Twenty-year-old Violet Sorrengail was supposed to enter the Scribe Quadrant, living a quiet life among books and history. Now, the commanding general—also known as her tough-as-talons mother—has ordered Violet to join the hundreds of candidates striving to become the elite of Navarre: dragon riders. But when you’re smaller than everyone else and your body is brittle, death is only a heartbeat away...because dragons don’t bond to “fragile” humans. They incinerate them. With fewer dragons willing to bond than cadets, most would kill Violet to better their own chances of success.
