Choujuu Densetsu Gestalt (Japanese)
When Father Olivier seemingly runs away from the order, Suzu the dark elf is sent to capture and return him to the order. Father Olivier has been having doubts about the legend of creation and decides to go to the forbidden island of G, named after the dark god who betrayed the council of gods and whose name is now forbidden from the lips of men. On his journey, a strange girl named Ouri is given to him as a slave. Fearing her fate should he refuse, Father Olivier soon learns that Ouri holds a few magical secrets of her own as she defends him from Suzu and all else that would impede his goals. It just might be true that Ouri really does come from the dark island of G.
