Prologue.

The year is 2196. 

Humans are divided into two groups: the humans, and the beasts.

That's what they call those who were born with blue hair. After the virus breakout in the year 2000, 80% of the world's population died. However, there was a change. The virus brought a curse with it, The curse of the blue hairs. After the pandemic, an extraordinary human was born, Zaibo Arthur. The first person born with the 'special power' The curse. He brought the world together as one under his rule. He restarted the redevelopment of humankind and brought peace to the world.

"The great Zaibo empire"

Ruled by the one and only, King Zaibo. But the thing he is known for the most is his superpower. 

Once he was targeted by an assassin. He stabbed King Zaibo right through his heart. However, at that time, the real superpower of the blue hairs activated for the first time.

"The ultimate Berserk state"

The advanced form of "The Berserk State"

Once a person born with the curse is in critical danger, his berserk state will activate. After activating the berserk state, only one person out of three can regain consciousness again. Those who don't however, are treated as a threat against humanity and are neutralized. Killed, basically.

The ultimate berserk technique is different. It provides 100 times more power than a normal berserk state. If someone undergoes the ultimate berserk state, they never regain their consciousness. That is how it's supposed to be, however...

King Zaibi, the first to be born with the curse, was different from any other cursed human. At his time, the curse was known as a superpower. But... It changed quickly.

 A normal person born with the curse lives up to 25-30 years of age before he succumbs to the curse and finally loses his rationality, the reason they are called beasts. The dangerous thing is, that they are like a walking time bomb. A normal cursed human lives up to 25-30 years of age, but there's no guarantee that they won't become mad before that age and lose all rationality. Thus, being the reason they are treated as nothing but monsters. They don't have any human rights. And are treated worse than animals.

King Zaibo was different from others because after activating ultimate berserk state, he retained his consciousness. And lived up to 85 before dying from old age.

 The curse does not pass through genetics, since his sons and daughters did not have the curse. After his death, his sons disputed and scattered the great Zaibo empire creating different countries.

2nd son received North and South America. 

1st daughter received Australia.

2nd daughter received Africa.

But the biggest fight started when the eldest son obtained Europe and the youngest son obtained Asia. The Eldest son received Europe but wasn't satisfied and waged wars with one who received Asia. With his mastery of strategy and great leadership techniques, he managed to conquer some of Asia and created the country,

"Teikoku Seibu"

The youngest son also created his own country,

"Azuma Kabe"

Even though the brothers passed away, their legacy and dispute are still alive through their bloodlines.

Teikoku Seibu was able to obtain every single blue-haired human that was discovered while Azuma Kabe excelled in technology.

This is the story of "Azar Morn" who was born with the curse of the blue hairs, out to avenge his parents' death, and fighting for "justice".
