Battler is the eighteen years old son of Rudolf and an unnamed woman, though he grew up believing Rudolf's first wife Asumu was his birth mother. He is very stubborn and is afraid of "shaky" transportation, thinking he might fall off of a boat, or out of a plane. Due to his father's remarriage, he rebelled and lived with his maternal grandparents for six years. After his grandparents died, he returned to his old home. He insists that the Golden Witch does not exist, and his denial of her existence becomes the main theme of the game. Most of the situations are seen through his point of view, and he is generally considered the protagonist of the story.
