Matthias is a half-demon. He is a cursed child. Hundreds of years ago, Vienstorian was plagued by many problems after the world war. So many citizens were starving and dying from disease. The king at that time was named Matteo Frederick Wandervelt.
He was very stressed, almost going crazy because he didn't know how to solve the problems that kept coming to his country after the world war, plus the deadly virus that had infected his people. He had tried everything, but his country was on the verge of collapse at that time.
In the end, he tried the last resort, which was to make a pact with the demon lord. But in return, he had to sacrifice all his worthy descendants after the first one, which was the second. The first one would become a king, so the second descendant would be sacrificed.
Matthias was the second child of Heinrich and Cathrine, and he was the one who became the next victim. But Heinrich and Catherine didn't want Matthias to sacrifice his life, and they tried everything to keep Matthias from dying, even though he was supposed to die at the age of two, just like their previous descendants who became sacrifices and all died at the age of two.
One day, Heinrich came to the demon king and made a deal so that his son could live, and not die, but he had to live after leaving behind hundreds of people and some of the inhabitants of Lyxstein. One of them is River Wolfeinstein, Dieter's older brother, that is why he wants to destroy Matthias.
But Matthias should live as a human and half-demon. A Witch named Nephadena or Nephada helped him seal his demonic powers and prevent him from losing control, but they still had to sacrifice a human every week.
Alice is one of the most beautiful mystique beings, with long pink hair and amethyst eyes. She is incredibly beautiful and possesses a power, one of the powers is in her hair that can heal wounds, internal illnesses, and make people look younger. Alice also became one of Matthias's sources of strength. Alice and Matthias are soulmates.
Matthias didn't tell Alice who he really was or the fact that he was half-demon, he was scared if Alice would leave him.
Darcy Linton has been by Matthias's side since he was just 1 year old. Back then, Darcy was still a teenager and chose to work as a royal driver while also looking after Matthias at the manor.
