Kurokawa Izana ( children)

Living in solitude, abandoned by her family and unrelated to the Sano clan, Izana, a mixed-race child, faced discrimination, grew up in an orphanage, yearned for family affection, but developed a distorted psyche, becoming the cold-hearted leader of Tenjiku before dying at the young age of 18.But before Izana was abandoned, she also had an older sister who always protected her, but who, while trying to save Izana when she was a child, lost her life in a huge fire in the very house that held so much happiness, all because a drunk man threw a burning cigarette butt at the door.
