Blue Dragon: RalΩGrado
BLUE DRAGON ラルΩグラド
In “Blue Dragon”, “shadows” can fuse with their "hosts". This is the history of the teenager, Ral, and his "shadow", the Blue Dragon "Grado", that his father, a king, imprisoned together in the dungeon of the castle when Ral was a young baby. One day, when the "shadows" besieges the castle, his personal educator, Mio, releases him to protect the castle and repel the “shadows”.
