As they rush the girl to the hospital, the two boys are almost struck by a truck but somehow emerge unscathed. Instead, they find themselves in a fairy-tale-like kingdom filled with a diverse array of people and wondrous creatures. To their astonishment, the boys realize that Yuu, who has been wheelchair-bound since childhood, can now walk! Yet there is no time to reflect on this baffling situation, as their friend has vanished. Determined to find Kotona, Yuu and Haru visit a local tavern to ask about her. But when they examine a portrait of Asha, the kingdom's princess, they make a startling discovery. Ni no Kuni tells the story of an extraordinary adventure in a magical world, highlighting the unique link between two distinct yet parallel realms and the bonds that connect individuals.
