Intro. Aoba Jōsai, nicknamed "Seijoh" or "Blue Castle" , is an elite combined empire in Miyagi Prefecture to the west, noted for being a balanced, strategic kingdom led by setter Tōru Oikawa. They are depicted as an imposing force, often referred to metaphorically where Oikawa is the king and his companions are knights (STORY INSPIRED BY AVATAR, of the Na'vi, but modifying some things).
