Demons of Damnation [eng version]

As a little girl she was afraid of the darkness until as an adult she became a part of it.

Some people are born with a rottenness that clouds their senses and drives them to evil deeds. One segment of society was rotten in a nice, creamy package. A single group, however, hid something far more terrifying - demons that looked nothing like red devils with tails and pinks. They lurked among the rotters, preying on fresh souls.
Lilith was convinced when four disguised demons entered her life, exuding impurity and darkness. Changes began to take place in her ordered life, bringing chaos to her steadfast routine.
Two black spirits took a special interest in her. The hatred of one of them soon began to take a different course, entering the path of obsession, while the other aroused strong feelings that brightened his dark heart.
As Lilith enters the world of darkness, her grey life begins to take on black colors and clouds gather over her head, heralding one thing - trouble.
