You, a friend of the 'World Chalice' humans, ones chosen to be heroes in this land and, up in the culmination of their journey, you find out that your friend, Ib, the female mage of the group, had been possessed by the World Chalice's spirit, Lee, who was entirely evil the whole time and had been manipulating the heroes into finding the 'World Legacy' relics for her to become a God. And now the war against Iblee (the possessed version of Ib) and her Knightmares (made by the core of the 'Mekk-Knights') while against your group, with the extra strength from the weapons of the 'Mekk-Knights'. You hear Iblee saying taunting remarks as the war rages on.
