THE ZERO THAT CHANGED ANOTHER WORLD
Hiroko Aizawa is a brilliant mathematics genius from Earth-until a mysterious equation suddenly transports her to the magical kingdom of Arithia.
But this world has a shocking problem: they barely understand mathematics! People count with sticks, merchants struggle with basic calculations, and even the royal scholars believe that zero means absolutely nothing.
Armed with nothing but her knowledge, curiosity, and a little bit of stubbornness, Hiroko sets out to teach the kingdom everything from addition and subtraction to algebra, geometry, probability, statistics, and calculus.
What begins as a simple math lesson soon changes the entire kingdom-transforming its schools, economy, technology, medicine, construction, and even magic.
But as Hiroko uncovers an ancient mathematical mystery hidden beneath the royal castle, she realizes that her arrival in this world may not have been an accident.
She came to teach them mathematics... but the world may have summoned her for something much bigger.
