In the year 4071, the world completely changed, and humans evolved into new species, which we called the demihumans.

Demi-humans are also called demi-beast they have tails and ears like animals, which make them a new gender which we called the second gender, rather than knowing that you're a male or female, the second gender will tell your rank in society.

Alpha is the top among the others, they had the power to rule and have different intelligent given, unlike the others. Their body also build differently, they have big bodies that help them be more dominant.

Beta is the most common species, 50℅ of the society is beta, they don't have the intelligence like alphas, and they don't also have the body. To be specific they like normal people, the most common people.

Omega, the third species, are like alphas, the only difference is that they will never win in strength. Omega bodies are built with small, smooth skin, and curvy bodies, which is the opposite of alphas' build.

Some people are gifted to have abilities, to help them in many ways, like quirks.

And because human has the characteristics of animals, which means that they also got heat and rut.

Being on heat and rut is a very dangerous and important day for every alpha and omega.

Being in a heat/ rut is dangerous, especially when they don't have a spouse or whom we normally know as a mate. It's very painful to be alone when you're in heat and a rut.

The rut is what we call heat to alphas, it can last a week or month, and it depends on the alpha and how dominant he is. Alphas who have no mate are very dangerous, they might kill, rape, or get pregnant. Those who were victims can be very traumatized because of what happened to them.

While heat is for omega, unlike alpha who got in a rut can make the omega traumatized because of their rut, omega is more became traumatized by their heat. Because when they are in heat they became completely different. They have the look of a vampish if they had or had not a mate. They also become more submissive to their mate or the one they choose to mate with, or the one they have sex with.

The one who was the blood of god or the devil receives special gifts, which are their special quirks or power.

Liora is an omega, but people who are not close to her won't know it because as long as she can remember is that she got a power that can change her appearance, which we know as a shapeshifter.

Many theories about Liora are that she is a beast, a man, a girl, and many more because outsiders would never get the chance to see her real appearance. The one who only knows her real look are her mother, father, and her three best friends, rose, enni, and soinna.

In this world, with the help of knowledge of people and mystified that we can't explain had developed the world into a different one.
