Yuu, Haru and Kotona, inseparable friends, live a peaceful high‑school routine. One afternoon, an ominous stranger chases and slashes Kotona—a tragedy that Yuu and Haru cannot avert. While hurriedly hauling her toward the hospital, they narrowly escape a truck collision yet emerge unscathed. Suddenly, they are transported to an enchanted realm teeming with diverse peoples and marvelous beasts.
To their astonishment, Yuu—who has spent his life in a wheelchair—now strides freely! Yet there is no moment to reflect on this bewildering turn, for Kotona has vanished. Determined to find her, Yuu and Haru pause at a nearby tavern to seek information. There, upon glancing at an image of Asha, the kingdom"s princess, they uncover a startling truth. Their search becomes as rumors of Kotona's disappearance spread across the kingdom, and they must navigate customs to locate her.
Through this extraordinary journey in a wondrous world, Ni no Kuni illustrates the unique bond linking two distinct yet parallel realms and how it shapes human connections.
