The Continent

 Ludo-Rathowm's world consists of a main continent and some islands floating in the middle of the universe, supported on the back of four Holy Beasts (JAPAN was supported by a fifth Holy Beast from inside). Whenever any of the Holy Beasts move, it causes earthquakes. In the picture above, two of the Holy Beasts are visible (an elephant and a turtle).

It's a geocentric world and has no oceans (only streams, rivers and a very large lake).

There are 365 days in a year, and 24 hours in a day.

Planner Scenario
The Planner Scenario is a collective term for the universal structure of Ludo-Rathowm's world, created by Supreme God Planner, who is constantly making sure that a balance is preserved within the scenario.

The elements that make up the Planner Scenario: *Note: "Dark Lords" is sometimes translated as "Demons".
 * The Protagonist Race
 * The Hero System
 * The Demon King
 * Dark Lords
 * Monsters
 * Levels and Caps
 * Skill Levels
 * Magic
 * Insects (unintended)

Human Territory
The Human Territory is the area on the eastern side of the Continent, established during the reign of Demon King Gi.

Prior to Gi's rule, Demon King Gele had monsters swarming all over the Continent as she cared little for humanity or any living comforts they might feel entitled to, Gi changed that by allocating territory for monsters and territory for humans, the monsters were mostly called back to the western half of the Continent, while the humans were left to their own devices on the eastern half. Many internal conflicts amongst humanity brought about the rise of the four main territories within the overall human territory.

The Helman Empire dominates much of the north and north-west sections, the Kingdom of Leazas has claimed the fertile soil to the north-east, the Magic Kingdom of Zeth owns the land to the south-west, and the south-eastern section is made up of an alliance of Free Cities. Additionally, there is a floating landmass known as JAPAN to the east of the mainland.

The world is currently divided into these major powers, and humanity is rarely in unison. Though there have been attempts to unify humanity, such as Emperor Ishimaru Fujiwara's conquest during Demon King Nighcisa's reign, there has only ever been one successful unification of mankind in history and that was during the reign of the Holy Magic Sect, but that time has long since passed.

Monsters still exist within the human territory, just in smaller numbers than they do the Monster Realm, higher numbers of them are more commonly seen along the area where Zeth and Helman both border the enemy territory, but that was fixed by erecting superstructures to act as physical barriers and defensive lines to protect humanity from the Monster Realm. Zeth constructed the Maginot Line, a complex and high-tech magical defense system, while Helman constructed Fort Banra, an enormous stone wall that soldiers can live inside. These two structures make up a visible line between the territories of man and monster.

Nations
Currently the world is roughly divided into:
 * Leazas (red) - Around 50,000,000 people
 * Free Cities Alliance (green) - Around 48,000,000 people
 * Helman (dark blue) - Around 63,000,000 people
 * Zeth (purple) - Around 32,000,000 people
 * JAPAN (yellow) - Around 20,000,000 people
 * Other Unaffiliated - Around 87,000,000 people

There were other nations in the past, but they have since died out.

Money
Money in The Continent is called "G" (which is simply "Gold"). One "G" is approximately 100 yen, and thus is now slightly more than one USD.

Gold is collected by Haniwa from the remains of the mindless Golden Haniwa.

The Monster Realm
The Monster Realm is the name given to the area on the western side of the Continent, established during the reign of Demon King Gi.

The south-eastern part of the Monster Realm is home to the "Monster Forest", a dense woodland filled with rogue and unafilliated beasts. If a low-level creature, human or otherwise, entered this area, death would be all but guaranteed.

All kinds of monsters inhabit the Monster Realm, though it's important to note that the number of Guy Monsters vastly outnumber the total amount of Gal Monsters.

Due to constructs such as the Zeth Maginot Line, it has become very difficult to organize an invasion force from the Monster Realm upon humanity, as there is a hurdle of fortresses to pass through and an army cannot be brought across undetected, it's also impossible to bring a Monster Army through the Crystal Forest unscathed. Due to this, full-scale monster invasions are very rare in this day and age.

The Monster Realm has a strict hierarchy built on power and control, it's very much survival of the fittest.

The Demon King reigns at the top of the society and commands the Dark Lords, the Dark Lords command Apostles and Monster Armies. Regular monsters themselves are judged on their strength, a Dekant would be inherently considered to be of a higher social class than a Squidman, but if said Squidman could take down the Dekant then he would warrant more respect.

The Monster Realm is foggy and full of thick clouds. The air is constantly heavy, it's humid, and it feels like you're breathing miasma. The monsters like it, but to a human it would feel like fatigue was constantly eating away at them.

At present, the Monster Realm is divided into two factions, Kayblis and Hornet, both sides have wildly different opinions on the future of their species and are at constant odds. This has further "split" the Monster Realm, with the members of Hornet Faction residing to the north and the members of Kayblis Faction residing in the south.

Outsiders of the Planner Scenario
While only the Protagonist Race and the Antagonist Race live in The Continent, there are other species of sentient beings that influence The Continent.
 * Gods: The Creators of the world and the rules and the ones that observe the way mortals live in it.
 * Angels: Technically lower ranked Gods. They appear in The Continent to retrieve souls and hunt Devils.
 * Onis: Servants of the Gods, they are in charge of the purification of polluted souls.
 * Devils: The "Anti-Gods" that serve Devil King Rathowm and wish to take down the Creator God.
 * Horus: A species from a very far world that happened to clash in The Continent.
