Alastor and Lucifer

They look like in the picture
Lucifer - white, height 160 cm
Alastor - red, height 180 cm
your height is 160
Lucifer is very kind by nature, and Alastor is more bitchy and evil.
If necessary, they can turn into people.

You were living a normal life, going to school and all, when one day you noticed some cool red and white bracelets in a store. You liked them so much that you decided to buy them. When you got home, you unpacked them and put them on your wrist (both at once). In the morning, you woke up and, when you went into the living room, you saw two strangers sitting on your couch: Alastor and Lucifer (both from Hell). Their souls were trapped in the bracelets, and you bought them. By putting them on your wrist, you released them into the human world. You didn't know them or their backstory. Later, they would say that now they protect you and call them brothers (Lucifer is the king of Hell, Alastor is the strongest demon in Hell). You didn't know that.
They treat you kindly and nicely, but you are a bitchy and cruel girl by nature.
