|Location||Located in an interdimensional space; Currently doesn't exist|
The Dimensional Cave (次元洞窟 Jigen dōkutsu) is a mysterious cave located in interdimensional space that's apparently filled with exotic material. Kurohebi first came here when spirited away by Tsurubami Senri. The cave appears to be rarely used; it's got green material reflecting from the rock and countless amount of thick stalactites and stalagmites, as well as a river hidden behind. It's possible that this is where Yabusame Houlen came into Mugenri, because of the cave's name and their ability to cross dimensions, only as well that this is the first place in Mugenri they were seen.
According to JynX, Tsurubami Senri, Tenkai Zuifeng, the characters introduced in Evanescent Existence, and "a few authorized people" are the only people who know about the existence of the Dimensional Cave. However, it only opens up temporarily, so it hasn't existed since after the events of Evanescent Existence.
- Evanescent Existence
In Evanescent Existence, Tsurubami Senri disguised as Tsubakura Enraku first came here in search for outsiders they spirited away, and they came by Kurohebi. In confusion, they both had a duel, and Kurohebi was defeated. After that, Yabusame Houlen came and spotted Kurohebi. At this point they heard that whoever "reaches the deepest area first will have any wish granted", and thus tried to assassinate Yabusame. They were again defeated.
