A century have passed and darkness is gradually eating away the light energy of the Planet Teriandhol. A war has taken place in order to fight to restore its balance. Claude who wants to stop the suffering and loss that is caused by this war, decided to step up. Possesing both dark and light energy, he set out on a journey.   He has the ability to harness dark energy by transforming into a demon or summoning one. But at the same time, he is also blessed with the Divine energy which one of its powers grow stronger through connections. Because of this, he has the ability to call forth heroes of the past who once served the first God, Jei-Sih and link with them during battle.
