World Description:
This world is still referred to as Earth, however, it's around 10x the size of the Earth that we know. Although this should effect the day/night cycle, for some reason, it doesn't (plot twist, hint hint). The world is infested with large bug-like creatures called "The Unseen", they're called that due to their speed, agility, and general ghost-like existence. They aren't ever seen when they kill, the only people who can kill them are called Transcendents. People who's power has eclipsed that of the Unseen. Unfortunately, the most powerful Transendent disappeared 15 years back, and since then humanity has been fighting a losing battle.
Transcendents:
Transcendents are people who can do the impossible, superhumans beyond the word superhuman. They are typically righteous individuals, people who fight for the sake of humanity at the center of cities. However, there are those who seek to end humanity, and give in to the Unseen. There are only about 50 million people left on the planet, spread across all the continents in large cities with about 7 million people per city, and one city per continent. These cities are connected with wormhole devices that allow rapid transportation between cities. There is one final city that connects to them all called "The Academy". This city's sole purpose of existence is to train new Transcendents how to fight the Unseen.
Power Levels:
Unknown: No-one has ever reached this stage before.
Godlike: There has only ever been one, the founder of the Transcendents, who vanished mysteriously 15 years ago. She was 1500 years old by the way.
Demigod: There are approximately 2 across the entire world. They exist in the highest class cities and fight the most powerful unseen. Someone who can destroy entire continents with one punch and traverse the starry skies without danger.
X: There are far more X-Class than there are Demigods, from this, one can see the difficulty in progressing to the demigod level. Someone who is able to destroy a small country with one attack.
SSS: Someone so incredibly powerful that they can destroy an entire city with a single attack.
SS: Someone who can destroy an entire block with one attack.
S: Someone who can destroy a building with one attack.
A: Someone capable of fighting a normal unseen general one on one and winning.
B: Someone who can clear a C ranked nest by themselves.
C: Inconsequential… weak.
D: Weaker than C. Can attack a C rank, it's not guaranteed that the C rank will feel anything.
E: Can attack a D rank, will likely get blown to mist with a single punch.
F: Can lift an office chair with one hand without feeling strain. May attack an E rank, but it's easier trying to outrun a nuclear bomb than it is to outrun an E rank.
Normie: Someone who is so weak they can't even look at Transcendents without feeling strain. Most of the world are Normies (about 95% of the population). If a Transcendent walks into a restaurant that a Normie is already eating at, the Normie will do everything in their power to leave the restaurant, because the longer they're in there with the Transcendent, the more suffocating it becomes. Normies have been known to die outright if a powerful Transcendent enters someplace without restricting their power.

Unknown: No one has ever witnessed an Unseen that has greater power than a Godlike stage.
Godlike: More powerful than a Godlike Transcendent by an order of magnitude of 1.2. Can easily overpower a Transcendent at the level of a God. It is unknown how much power a single punch of a Godlike carries.

Normie: This rank of monster won't ever be seen. Monsters/Unseen are powered by an energy core constructed of complex mana structures and filled to the brim with qi. Monsters can wield both. Most Transcendents can only wield one. Only the First Transcendent and her descendants are known to be able to wield both. It is unknown why.
Monster talent levels are the same as Transcendents.
