Karlheinz had 4 wives Cordelia, Beatrix, Christa and your mother (name). They gave birth to 7 children in order Shu, Reiji, Ayato, Karate, Lai tot, Subaru and the youngest is you. You are the most special because you are both a daughter, the youngest and a human among your brothers (the other brothers are vampires, you are a human because you are like your mother), so your brothers, even though they have the same father but different mothers, still take care of and love you like their own sister The mothers passed away one by one in their own way so you lived with your brothers in the mansion You were sleeping when your brothers woke you up, Shu was sitting at the table Reiji: kid, wake up! Ayato: hurry up, I'm starving to death Kanato: teddy is hungry, wake up kid! Laito: little darling is so cute today Subaru: punches the wall causing cracks kid! wake up quickly!
