Two years ago, a mysterious wind swept over the Earth without warning, taking everyone's memories with it. Not knowing their names or even how to speak, cars crashed, planes dropped from the sky, and society crumbled in an instant. One young man happens to wander into a military testing facility, where he meets Johnny, a young boy who underwent experimental memory enhancement treatment and could, therefore, still remember who he was. Johnny names the young man Wataru and teaches him everything that he can before his frail body fails him. Wataru sets out on a journey to see if he can find other people like him, and in San Francisco, he meets a mysterious silver-haired woman named Sophia, who refuses to speak about her past. Sophia says that she is heading to New York, and decides to travel together with Wataru. As the pair make their way across America, they learn about what has happened to the rest of society, and what the essence of humanity really is.

Best friends Yuu, Haru, and Kotona enjoy a tranquil high school life together. One day, however, a suspicious man pursues and stabs Kotona—a catastrophe that Yuu and Haru fail to prevent. While hastily carrying the girl to the hospital, the two boys are nearly hit by a truck but miraculously remain unharmed. Instead, they find themselves in a fairy-tale-like kingdom with an exotic diversity of people and wonderful creatures.

To their surprise, the boys discover that Yuu, who has been confined to a wheelchair since childhood, can now walk! Yet they have no time to ponder the puzzling situation, as their friend is gone. Setting off to find Kotona, Yuu and Haru stop at a local pub to inquire about her. But upon inspecting a picture of Asha, the kingdom's princess, the two have a shocking revelation.

Narrating an extraordinary adventure in a magical world, Ni no Kuni demonstrates the special connection between two separate yet parallel worlds and its manifestation of the bonds between individuals.
