When Yu Narukami moves to rural Inaba, he expects more peace and quiet than he's used to in the big city. Instead, the peace is shattered as a rash of mysterious murders and kidnappings sweep the countryside. With the police stymied, Yu joins a group of eight other teenagers in a desperate bid to solve the mystery--a mystery that is somehow connected to both the local weather patterns and a strange "TV World" which Yu, his friends, and the enigmatic killer can all enter.

 

Many years ago the world was divided into two stars, the Eastern and the Western, that were connected by a bond known as the Dragon Pulse. On the Western Star, Jeanne D’Arc is shunned as a heretic for her visions of a champion who will save the planets that have become embroiled in war. Now the fate of two worlds hangs in the balance as, at the order of King Arthur, Jeanne travels from the West to the East with Leonardo Da’Vinci at her side, in search of their long awaited savior- Nobunaga!
