Elise Guttierez is a miserable woman in her 30s, who bore a son from a man who didn't even love her so she and her child are often the victims of abuse from her husband.
When her husband died and her son began to suffer leukemia, she suffered depression and chose to end her own life by falling off the building. But she was stopped by a strange child who took the form of her dead husband's childhood and offered her a chance...
"Poor girl, the sins you committed in your past hindered you from living a happy and successful life. Do you wish to be given a second chance and correct your mistakes?" the boy asked.
Elise only nodded at his question.
An evil grin began to plaster the boy's face and he gave her a mask. "From now on, in exchange for the power to reverse your time, your soul will be mine and you'll become my grim reaper."
Elise slowly fell into a state of unconsciousness. But before everything went black, she heard the last sentence the boy spoke.
"Don't worry, it seems that I already know who is going to be your familiar."
