with her is made of pure tenketsu, the blood of angels, the primary source of energy throughout Ai-Land. If humans touch it, it leads inevitably to death. If Dougen touch it, they eventually get a narcotic reaction. She remembers in chapter 12 that Queen Lilith isn't her real mother but she still has the royal birthmark of a red rose on her right thigh.
