The Onii Kingdom is the first kingdom that Corobo explores, ruled by Onii King. It is located in the southeast of The World, and is inhabited by many Onii, most of which leave and join other kingdoms after the Onii King's defeat. Later, wild animals overrun the Dark Valley.

To the southwest is the Sunflower Plains, and to the north is Farmland, which was once Meadow over the Bridge, an area which previously belonged to the Onii Kingdom.
