One thousand years ago, dragons and Witches warred against God for the fate of the world. God's power was triumphant, but it was a difficult struggle, and the deity sent Himself into a deep sleep to recover from the terrible wounds he suffered in the battle. Ten years ago, the Church has proclaimed that a great event will soon occur: God will be reborn, and the world will be led into a new golden age under His guidance. However, the witches are also fated to return, and the world is doomed to conflict once again. Take control of the Garden Children, a group of fighters and mages trained since childhood and dedicated to eradicating the Witch threat, and discover the mysteries behind their return, their motives, and their history!

Luminous Arc splits its gameplay into adventure and strategy parts. During the adventure sequences, you converse with other characters and progress through the storyline. You can move between locations on a world map and purchase items and weapons from a shop. The game will feature voice acting, apparently from a famous voice cast. Strategy sequences take form in grid-based battles, with players placing their attack squad and then taking turns attacking with stylus-driven moves on the gridboard.
