Legend says that there once was a Mythical Dragon, said to be the ancestor of all Mages. A powerful yet benevolent creature who always assisted the humans with their daily hurdles. From a single sphere of mana, he shaped and formed the Promised Land. This world was a place full of miracles and the Dragon allowed the humans live there so long as they promised to repay him a favor one day. But living in this sanctuary allowed the humans to become greedy and lazy and as such never returned the favors to the Dragon. When he threatened to kick them out of the Promised Land, they revolted by impaling him with specially crafted poisonous swords and burying him deep in a magic forest.
Fifteen years ago, a Mage had the idea to hold an annual competition known as the Mage Wars. Every year sixteen powerful Mages were chosen to fight in a battle to the death in order to determine who gets to go to the Promised Land. One Mage named Yuuji Yuki dreams of ending this war, but will it be as easy as he thinks? Or will he find out that no matter how hard you try, some things you can never change.
