Auxiliary

First thing to know is that this is the first time that I'm creating a story so its bound to have some bad thing but whatever. 

World Building:

In this world humanity has evolved to make it that they are capable of doing miraculous things such as flying, super strength, and super speed etc. 

This is all thanks to the energy they have access to which is called Evolution Force also know as Evo Force which comes from a mysterious entity called Darwinism. 

The Evo Force in humans are measured in tiers starting at the lowest, tier 0, this tier is for regular humans before having started evolving their Evo Force which is evolved through killing other enemies. The tiers 1-3 are the Auxiliary tiers where they are introduced to the powers that they could wield in the future. Tiers 4-6 are the average for adults people don't go past this due to the enormous talent and resources needed to evolve past this state. Finally tiers 7-∞ are the stages after and nobody knows where it truly ends the highest recorded is tier 10 that the former monarch Arthur Von Der Leyen achieved.

In this day and age the human race has been united under one banner and fight against sexism racism and other problems like that, however no matter much they improve in things like that people like Alexander are victims to all types of discrimination.

The human race is ruled by a monarch and three main noble houses, The monarchy is called Von Der Leyen The first house which you already know is called Von Kregg, The second house is Von Der Brüggen, Von De Romanov. 

The house of Von Kregg with is rules by Victor Von Kregg, their house is known for their strong fighters who have lots of potential, however they are mostly fighters and are rarely academics which causes them to not be able to do business and other things which require such talents. 

The house of Von Der Brüggen, is ruled by Alfons Der Brüggen, their house is essentially a business empire with them owning 90% of businesses all over mankind's reach , their monopoly over the business empire leads them to mostly grow fat and weak in the comfort of their own homes leading their house as a whole except for a few individuals to be weak.

The house Von de Romanov is ruled by Maqsum Von De Romanov, their house is devoted to improving science and understanding of the Darwinism, their devotion has lead them to make many discoveries in the field of Evo Force and other things. However due to them being mostly researchers they are not known to be able to fight and only due to the benevolence of the monarch they are able to survive the ruthless world that wouldn't hesitate to kill them for their knowledge.

In this world humans aren't the only things to get the Evo Force and animals have also gotten them causing them to evolve to a superior version of themselves that isn't controlled but more so tailored on a path.

The house of Von De Romanov have been able to imbue Evo Force into weapons and other things causing them to be called evo weapons E.g. Evo gun , Evo sword etc.... .

Mc:

Heir to house Von Kregg, Alexander Von Kregg an 18 year old man aspires to become an Evo Soldier and fight for humanity against various alien races but has not the power to do so leading him down to a different path than most in search for power.
