Monster Soul  The tale of Monster Soul takes place in Elvenland, a fictional land that humans and monsters inhabit. The main characters are a group of monsters called the Black Airs. The Black Airs is recorded as the strongest group of the monster forces in the great war between the humans and monsters. The first three chapters consist of three stories that do not have a main plot, but the last chapter of the "first stage" reveals a bit of the past. In the "second stage" the Black Airs travel to Hell to help a human boy save his townspeople who are captured by the evil Tri Command.
