Shore Of The Beginning

Meanwhile, in a place few would wish to enter willingly, a beautiful black-haired, golden-eared, golden-tailed woman dressed in a classical European maid outfit appeared on a black shore.

Above the beautiful woman was nothing but an empty black sky.

Only in front of her, there was something - an endless seven-colored sea— The Sea of Sin.

Each color in the Sea of Sin represented one of the Seven Deadly Sins: 

Pride - Violet

Envy - Green

Greed - Gold

Lust - Pink

Gluttony - Orange

Wrath - Red

Sloth - Blue

The Sea of Sin was the beginning and the end for every Soul, who was judged evil. It marked the beginning of a new life and the end of their past life. 

In other words, once one began their journey on the Sea of Sin, their past life's sins would be left behind.
