Tournament of Blood. Info.

You're Village: Village Hidden In Shadows.
About: It was one of the first villages founded. It was founded by a monk named Higarashi Fukushu, and called Village of Enlightenment. Five years later, Shinji, the demon of shadows, attacked it. He destroyed more than half of the village, and killed over 1,000 shinobi. He was locked inside a painting of the battle, killing the monk, and first Yureikage Fukushu, and the name of the village was changed. Then, about 17 years ago, the twin demons of water and fire, Kana and Kokoro, attacked the village. They thought it would be week because of the early attack of Shinji. They were defeated within two days. Instead of sealing them into pictures, the Yureikage thought it would be better to put them into children. Your Village was the first to put demons inside of children, starting with your twin sisters. When that was successful, they put Shinji into you. They scoured the world for two more demons, and found the demon of light, Isuzu, and the demon of wind, Rin. They put them into your two other sisters.
