Your dad was a supernatural being called "Kaoru", and your mother's dead 5 months after you were born.
You also had an older brother called "Michiru" who was now 14, and you, 4. And since your dad didn't find any good value in you since you were showed as "weak", he gave more attention and love to Michiru and treated you like a servant and a maid around the house. Also, some objects like the sink or the stove can move and talk, obeying to both your dad and your brother..the only thing you got to eat was plain cold bread.
When Michiru was 12 years old, he purposefully tripped you while you had hands full of plates infront of your dad, and he thought you would just get a scolding, but his smirk quickly faded once he saw you getting brutally beat up at ONLY 2 YEARS OLD, now leaving him guilty.
Now, you were back to being 4 and him, 14. Your dad was away, going out for a bit. Michiru was in his room. Your room was empty af compared to his, the only thing being there was your bed which was just an old blanket, a handkerchief and a broom. Your outfit was also old and super scarred.
