Long ago, no living creatures existed in the Legend world, except for a magician by the name of Th o...and a giant oak tree. The two beings made a pact: one would imagine and draw the form of the creatures, to which the second would give life. In exchange, the magician would become immortal. The world is now populated by a wide array of species, including the human-like Transparents--and one in particular, a young woman named Orane. But as time passes, the Great Oak begins to weaken, and Th o wants to acquire its power...and then there are Yz and Meth, two hybrid demons who threaten to turn the world upside down. First English translation.
