Original title: 超獣伝説ゲシュタルト

Oliver is a young priest of that Vasaria order, and a devout servant of his church. He has grown up with legends of a god who dwells on G, a distant island so forbidden that even speaking its name brings certain damnation! When Oliver saves the mute girl Ohiri from slavery, their destinies become intertwined and they set out on a perilous journey to G. Actually a silenced sorceress from the forbidden island, Ohiri is involved in a deadly game of survival that brings her and Oliver face to face with treacherous dark elves, powerful elementals, and a quest filled with plot twists, magic, and wonder.
