Ni no Kuni II: Revenant Kingdom is a role-playing game played from a third-person perspective. Players complete quests—linear scenarios with set objectives—to progress through the story. Outside of quests, players can freely roam the open world, where they explore towns, villages, dungeons, and other dangerous places scattered throughout the world. Upon leaving a location, players enter the World Map, which can be used to select a destination; the overworld represents a diarama, and the characters are portrayed with a chibi-like design.

When players encounter enemies, they enter a battle system. Battles take place on an open battlefield, allowing players to freely roam around the area. During battles, players command a single human ally; all characters are manually moved around the battlefield. To fight enemies, players use melee attacks, magical abilities and “Higgledies”. Higgledies are “spirits of hearts” which exist in several forms, and may represent elements. Players also use Higgledies to reach far areas and to clear and explore dungeons.

In Revenant Kingdom, players have the ability to build and manage the kingdom, focusing on the arrangement of work-forces within the town.

Set hundreds of years after the events of Wrath of the White Witch, Revenant Kingdom features the cat and mouse tribes, two warring factors in the town of Ding Dong Dell. During the events of the game, the mouse tribe performed a coup d’état, taking control of the kingdom. The story follows Evan Pettiwhisker Tildrum, a boy king of the cat tribe, who is usurped from his castle and sets out to reclaim his kingdom. He is aided by Roland, a visitor from another world, and Tani, the daughter of the boss of air pirates.
