DEMON LEVIATHAN( THE BANISHED SON OF LUCIFER

In Ancient times, killing and sin were prohibited.
Angels roamed the face of the waters freely all free of sin and so pure.
After so many years an angel broke the law out of envy and destroyed an angel which led to his banishment.
The angel he destroyed survived and was among the league that sent him away.
He was sent to earth where he stayed for a long time alone but then he was wise and he made a few of his brothers above fall and join him.
He destroyed, killed, and did so many evil things he was known for but still, he felt lonely.
The Supreme being seeing that the punishment wasn't enough created a fire-burning kingdom he called "Hell" and sent the fallen Angel with his demons into and sealed it.

For years the Angel known as Lucifer and his demons but somehow they unsealed the kingdom having freedom again.

Roaming through the earth once more as he always did he caught a glimpse of a gorgeous hot damsel and against her wish slept with her and made her his.
At the birth of his son, his wife died which made him banish his son from his presence at a very tender age and drop him in an orphanage home.
The boy knew who he was and in the orphanage carried out so many evil acts for his father even without being told to.
His name is Demon Leviathan.
Half-human, half-demon.
Fury is his second name.
He is a man of horror and terror.
What is his mission?
Will the orphanage get to know who he is?
Is there a lady meant for him?
Will he get to meet his demon father?
Will he fight against his father or join him to fight against humans.

This story will start from the very beginning not halfway.
