In this game, the story is set in the mythical Eternal Feather Kingdom, a once-prosperous land protected by divine beings that was destroyed by a demon, leaving it vanished from the world. A few chosen individuals, known as 'Feathers,' safeguard sacred gemstones that grant them special powers to combat the demonic forces, with the protagonist being a regular high school boy from the modern world who becomes a Feather after receiving a divine gift. It stands out with its blend of mythological themes, where ancient prophecies intertwine with modern characters, and features advanced gameplay elements such as strategic battles, character progression, and puzzle-solving, all set within a richly detailed fantasy universe.
