"Nice to meet you, Sage. Welcome to the broken world."
On a full moon night, with the wind howling and cats stirring, Akira Maki, who had been living an ordinary life, suddenly finds himself in a world where wizards and humans coexist.
This world, made up of five countries, is plagued by the Great Catastrophe—a massive moon that invades once a year.
The Sages of the Wizards, who have the mission of fighting and pushing back this moon, are led by an "Otherworldly Sage"—and it is as this very sage that Akira has been summoned to this world.
To fight the moon, to save the world, and above all, to become a bridge between humans and wizards.
Living through endless time and following his heart, Akira strives to connect with the wizards, who live by their own rules and magic, offering his support and effort to strengthen their bonds.
"I hope that one day, we can become friends."
In this beautiful yet terrifying, crumbling world, Akira’s unforgettable and mysterious days with the wizards begin.
