Honōnowa (ホノの和) also known as Honō no ji (炎ランド) and Mount Kasai (マウントファイア, Mauntofaia). Hononowa is a group of mountainous islands in the Land of Demons. There are over 400 islands in the chain. It is known to be the place where Yanikosa Shanto was born. The route to the islands is long forgotten by humans and is where all oni live. It is extremely hard to navigate through the Lava Reefs that surround the islands. The islands are created of hardened lava and it is not rare to see lava rivers flowing into the ocean, or volcanos erupting in the distance.
