Hell of Blazing Fires as seen in Subterranean Animism.

The Hell of Blazing Fires', or more accurately, the Remains of the Blazing Hell (Shakunetsu Jigoku Ato, 灼熱地獄跡) is located below the Palace of the Earth Spirits. It is where Stage 6 of Subterranean Animism occurs. Formerly a part of the underground Hell where criminals were banished, it has recently been re-ignited by Utsuho Reiuji and is now being utilized by the Kappa of Youkai Mountain as part of their Mountain Industrial Revolution project.
