"Hell" is the name given to one of the largest areas in the game, also known as 'The Red Maze'.
It is one of the most significant deeper locations in the dream world. Many routes from The Nexus will eventually lead here, allowing for many connections between remote areas. There are even some locations that are only reachable by finding its one entrance through this maze.
The navigational difficulties created by the intricacy of the maze are compounded by a number of lunatic Toriningen wandering the narrow passages. Many of the paths appear similar in shape to those elsewhere in the maze, which can be disorienting - even with the benefit of a map.
This is one of the few places you can get a "Heart" and links to many maps. Oftentimes maps leading here have Toriningen blocking the way. Madotsuki's ghost is located in another red maze area, but this area is not connected to the larger Hell.
- A red one-eyed monster can be found in the middle of the maze. If stabbed, there's a 1 in 256 chance that Madotsuki will be transported to the footprint path in Eyeball world.
Trivia
- In the beta version of Yume Nikki, something resembling a funhouse mirror could be found in one of the largest rooms of the maze. This item gave Madotsuki the Fat effect. It has since been removed, and the Fat effect is now found in The Docks.
- While hell is not technically the largest area in the game, its maze-like structure makes it slower to explore than any other place.
