¶ The Continent - Also known as the Rudrasaum Continent, this is a massive island the size of a continent. Carried by four beasts that move forward every once in a while. Atop of it lived two races and two realms where 5 countries existed.

¶ Protagonist Race - The race who suffers a lot. The current Protagonist Race are now humans, which our protagonist, Rance was part of. Dragons and Round Ones were the previous Protagonist Race respectively.

¶ Kalars - An all-female race.

¶ Antagonist Race - Monsters, collectively. In different shapes and sizes and personalities, yet all types look the same, really.

• Guy Monsters - The collective term for male types of monsters. Most of them have little to no morality, working under a set personality that separates them from the norms

• Gal Monsters - The collective term for female types of monsters. Most commonly seen are Can-Can Rabbits, green haired girls wearing a set of light pink underwear.

¶ Nations - Where the Humans live. Technically, there's the monster realm where most Monsters live, though other monsters prefer being around the Human Realm.

• Leazas - A country living in a very fertile land. 55 Million live here, whereas there are 22,000 (or more) that worked in the army of Leazas. Always on war with it's neighboring country, Helman who wanted to try to take back what was once theirs. Currently in the process of being liberated by the Leazas Liberation Force.

• Helman - A country that is mostly under cloudy skies and cold climate. Apparently a sexist country where women are discriminated. It's rare for them to become Soldiers, and it's even rarer for them to become Knights. The common food you can get in restaurants are only bread that is hard to eat (some have tasty bean paste inside) (also feels like you're eating rocks), boiled potato, and a bowl of boiled and salted meat soup. On another note, the nobles there were deliberately chosen to be quite incompetent, wonder who could be doing this....

• Zeth - The kingdom of Magic, that repels monsters coming from the Monster Realm at the west through the use of the powerful Maginot Line. Like Helman, it has a horrible social system that separates the magic users from the non-magic users, treating the former as nobility and the latter as weak commoners. Tribal cultures in that country are mostly extinct.

• Free Cities Alliance - It's actually just an alliance of several cities and towns at the south of Leazas, Rance and Sill live here (currently).

• JAPAN - Located at east of the Free Cities Alliance, a massive floating island similar to our world's Japan held stationarily by the Tenma Bridge that the 2nd Class Goddess, Amaterasu created, which connects the country to the continent.

Now, to the other stuff.

¶ Levels and Level Caps - Every single person in the Continent has levels and level caps, even their skills. It's common for people to be born with Level Caps 20 and below, and less common when their Level Caps at 30 and above. The strongest humans in the Continent have a Level Cap of at least 70 and above, while our protagonist (and certain people) has absolutely none. Also, apparently you can fight 1st Class Gods (strongest gods weaker than Eternity Gods, Supreme Gods, and Rudrasaum) when you're at least Level 800 or way above.

• How to Level Up - Simple, you kill anybody, go to a Level Shop or summon your contracted Level God, or in an alternative way, train really hard.

• Level Decay - Doing absolutely nothing and lazing around will slowly decrease your level. Though this doesn't affect people who are Level 1 or are Level 0, and even Rance, who cannot follow laws that doesn't even benefit him.

• Skill Levels - Everyone is born with a skill om them, if not, that certain person probably has several Level 0 Skills. By the way there are three Levels to Skills, and Level 4 doesn't exist. Level 1 is simply for professionals, Level 2 is beyond professionals, and Level 3 is for literal legends. Even so, when you have a high level in a skill, for example, Level 3, you still need to polish and train that skill to not let them rot down and make you weaker.

Alright, let's put another thing to the equation:

¶ Demon King - The Ultimate Lifeform, the strongest being in the Continent and the Leader of the Antagonist Race. The weakest Demon King is as strong as a 2nd Class God, and the strongest being equally strong as a 1st Class God. Usually being between 1st Class and 2nd Class in power, they are driven with intense bloodlust and drive to make the Protagonist Race suffer. The current Demon King is Little Princess, though you might meet her way later.

Demon Kings have an incredibly amount of strength and vitality, normal magic to them is equal to Level 3 mages, too. They could fight for years without end, stay awake for hundreds of years, and some other stuff normal humans could do.

However, as of the 3rd to the current Demon King, they only live for around 1000 years before their powers begin to wane. At this period, they must transfer their blood to a suitable host.

• Invincibility Field - A field that the Demon King and his/her subordinates have, which makes them impenetrable to any sort of damage. As long as anybody had the intent to hurt, it would react.

• Weaknesses - Even so, such a powerful barrier would need drawbacks, right? Let's just say that it only lets high-class gods, other Dark Lords, or the Demon King him/herself. One skilled warrior could use a Dark Lord/Demon King's own energies against them to effectively damage them. Certain weapons, such as the Escude, Chaos or Nikkou can bypass the Invincibility Field, too.

¶ Dark Lords - Subordinates of the Demon King. Has around 0.8% of the Demon King's power and only 24 are allowed to exist.

• List of Dark Lords known in the story so far:

• Ithere

• Satella

¶ Gods - Powerful beings that reside under the uppermost layer of the continent. Most of them are amused at the suffering that was above, and are pretty neutral to the world unless something were to happen.

• Ranks - Each gods have their own ranks, and they can rise up through completing several different tasks, or they are assigned to a specific rank for a job well done. The weakest gods are those of 11th rank, and the strongest are of the 1st Rank (with the exception of Supreme Gods and Creator God Rudrasaum itself.)

¶ Devils - Entities residing on the Devil Realm, has their own unique laws, customs and other stuff. Like gods, each of them have their own classes.

¶ Rance - An anomaly. Originally should have been a very perverted bastard that cares only about forcing women on "forced consensual sex", who either becomes the Brutal King or a Demon King through seven years of adventure. This anomaly (mostly) doesn't follow the rules set by the Supreme God Planner, choosing to go actively against it and him unknowingly.

Technically, the Supreme God hates him with utter spite, yet couldn't do anything to completely get rid of him because of the Creator God's intrigue, even with that immense, neverending growth his soul was having.

The anomaly could absorb souls within the vicinity of 300 meters around him, and to be honest, souls absorbed by him would no longer be Rudrasaum's, one of the causes why Planner hated him with pleasure.

Aside from that, with the astronomical amount of XP he has, he could become a threat to the gods soon enough.

¶ Sill Plain - A loyal servant of Rance. She will be loyal to him even if he is dead until she dies. The girl was rescued (read: bought) by Rance one year ago, and ever since then, she was enjoying her life as his slave.

The difference between her and her original counterpart is that the original is kinder.

This Sill has dark thoughts sometimes showing inside her, though wouldn't show that in front of Rance in fear of being left.

She barely hesitates following all of Rance's orders. Like the loyal slave she is.

Sill Plain is one of Rance's fated women, even if she didn't know that.
