The Birth of a Demon

I am Oni Sanran. A demon. A devil. My twin brother and I where born on Earth from a corrupted couple. Both of them died right after. My name literately means "Demon Spawn" in Japanese and my my brother is Akuma Sanran. His name means "Devil Spawn" in Japanese. My hair is a dark red, I have dark gray colored eyes, pale skin, I am 4'11, I am a smart student, and I have medium sized breasts. My brother looks just like me, however his height is 6'4, and his eye color is a misty gray. And an obvious is he is a male. We where abandoned by everyone we knew because we have powers. I can kill anyone with black tentacles and hands from my back, I can bring back the dead, I can open portals, and I am able to travel from Hell and Earth. My brother can control people's minds, take over their body, create illusions, and hypnotize them. We live in a field quite a way from the city. Our house is a one-story, we have a lake behind our house, the water is mirky gray when we are in the house to open portals for Akuma. Satan is not our father and never will. My 'Best' friend is an angel named Tenshi no Tsubasa a young angelic girl with light blond hair, light blue eyes, clear peach skin, and never dresses in any dark colors. Her brother, Gadianu no Tsubasa, is her twin brother. They look just alike, however, Tenshi is a girl and is shorter and Gadianu has light green eyes. Gadianu is Akuma's 'best' friend and they too don't have parents and live alone. On the weekends all four of us would meet up and hang out around the city Tenshi and Gadianu would sometimes even have races with Akuma and me. I never had seen my mother and father, nor has Akuma. I hope we can figure it out though. As well as to figure out who's Tenshi and Gadianu's parents are.
