All throughout history, there was always a fight between the Heavenly Yard and Hellish Yard.
The Master of the Heavenly Yard is the most holy of spirits, always thinking of others and protecting the peace and balence in the world.
While The Master of the Hellish Yard,
Wants only power and domination.
Constantly these two powers fight amongs each other in their world.
But each time they fought.
The Master of the Hellish Yard got stronger and stronger cause of these strifes.
Worring the Heavenly Master.
It made him result to something sinister that he wish he didn't have to do.
He invented Sin.
Using 7 different Sin from 7 Sinful people he sealed the Hellish Master, stablizing his murderous needs.
But it came with a price.
The seal only last for 700 years
For humans that seems really long
but for gods, angels, and demons, it only last 7 years.
So every 7 years
the Heavenly Master choose two individuals to venture to the human world to find Sin.
To make sure that the Hellish Master does not get stronger.
"Maaaaaaaan what a lame story!" Vrisko said, with his usual bored look. "You Angels tell the story of Sin wayyyyyyyy more 8oring than the one in the Hellish Yard."
"Can You At Least Be A Bit More Considerate" Kanayo said "I Was Raised Off This Little Story And I Still Wish To Be One Of The People Who Gets To Find Sin"
"What a crappy dream. So what? You get to find sin, kill off a few humans to keep the demon dum8ass at 8ay woopdeedoo." Vrisko said with a monotoned accent.
"Tell Me Why Are You My Moirail Again..."
"Caaaaaaaauuuuuuuuse you have a crush on me?"
"Dont Use Human Words"
