This dimension is an alternate space where Nue resides. It can be reached by activating the Gozu Tennō a Space–Time Ninjutsu, while also having a link with Boruto Uzumaki's Dōjutsu. After Boruto cancelled the Gozu Tennō, the space would seem to collapsed with the seal.
This place is similar to an underground cave. There are several swamps with trees similar to mangroves. These are connected to each other through a network of lianas and ropes. Nue's den is inside a large trunk of hollow shaft.
