In the mobile fortress St. Al's Magic Academy far away from the land, an anonymous invitation draws 13 participants with secrets into a game of life and death. "Answer the true name of the Lord, and any wish will come true." Behind the seemingly tempting promise is endless suspicion and bloody game.
The down-and-out nobleman Feld, the mysterious Japanese girl Izanako, the cold and angry Cain, the cowardly saint Daphne... Everyone searched for the truth in six ancient magic towers, but encountered strange secret room murders one after another. The crazy experiments of the Gnosis School, the forbidden rituals of the Secret Moon Magic Tower, and the eternal puzzles of the alchemy labyrinth push the participants step by step into the abyss.
The exchange of information at the daily tea party hides murderous intent, and the metaphors of fate revealed in tarot divination are difficult to distinguish between true and false. The mysterious control of the Chant Club, the shadow of the werewolf legend, and the ultimate answer to the "True Name of the Lord" become increasingly confusing as the number of victims increases. When magic and reason collide, faith and betrayal intertwine, is this feast with life a test of the gods or a game of the devil?
Concept: In the triple spiral intertwining of magic, religion and science, a glimpse into the puzzle of faith and human nature
