The perfect symmetrical love (Death the kid love story)

This is a story about a Shinigami girl. Her father is Satan a god of death and her mother was his weapon. Her name was Angel and she is god's daughter and a god of life.
Anyway. That way she had the abilities of god of deaths and lives. The Shinigami teen was so bored down there so her father sent her to the 'real' world. Satan told her to go to Death city because it's a city of a friend of his'. So she went to go to Earth. She has (as you guessed) OCD which leads to her weapon choice. She has two boys,twin brothers, as her partners. These two were living on the street and she bumped into them when she was taking a walk.

Follow her through her adventures in the human world.
