Choujuu Densetsu Gestalt

A priest named Father Oliver abandons his religious order to investigate a dangerous island known as "G," where a deity named Gestalt was exiled long ago. The island's name is taboo due to the god's feared power. On the island, Oliver meets a young girl named Ohri, who possesses considerable magical ability. The religious order's leader sends a dark elf named Suzu to retrieve Oliver, but she is quickly overpowered by Ohri. Despite this, the island presents numerous challenges, including hostile creatures and other magic practitioners who hinder their journey.
