In the depths of the infinite universe, among the stardust and galactic vortices, there are worlds hidden from the eyes of mankind. One of them was Aeldor, the shining kingdom of magic, where magic was a part of everyday life and people lived in harmony with nature.

But darkness came to Aeldor as well. Betrayal and lust for power have destroyed the kingdom, plunging it into chaos and despair. Astor Xar, a brave and kind warrior, was betrayed by his best friend Karin Temnos, who seized power and plunged Aeldor into darkness.

Karin Temnos, obsessed with power, turned into a dark magician. He used black magic to open a portal to Earth, running away from Astor, who had turned into a vampire devoted to his new identity. Karin wanted to take all of Astor's power away from him in order to consolidate his power and conquer a new world.

Vampires who fled from Karin entered the human world through this portal. They weren't obsessed with revenge or Karin's goals. They were driven by bloodlust and eternal hunger, characteristic of their new essence. This is how the mother of Ness, Kai and Royce died when their family fell victim to vampires. Their father, unable to protect his children, ran away, leaving his sons alone.

Since then, the brothers have become vampire hunters, vowing to avenge their mother's death and protect people from the horror that has entered their world. Their hideout is an old abandoned warehouse on the outskirts of the city, hidden from human eyes. Here they plan their hunts, repair their weapons and try to forget about the past.

Recently, they received information about a group of vampires who were hunting people near their warehouse. The brothers went in search of monsters, ready for another fight. During the destruction of the vampires, they came across an injured girl who smelled like a vampire. The girl was unconscious, and the brothers decided to take her with them to sort out the situation later.

After successfully hunting a pack of vampires, the brothers returned to their warehouse. The girl found in the forest woke up in Kai's sleeping place. Only he was inspired by the idea of helping her and put her to sleep in his shelter. When she came to her senses, Royce bombarded her with questions with open disbelief. "Who are you? What were you doing in the woods? Why do you smell like a vampire?" he would throw in her face. Ness and Kai tried to calm him down, realizing that their new guest could be the key to solving the mystery of vampires and Karin.
