Moon of Saturn: The Arcana System.

Kaito Hara never asked for anything more than an ordinary life. But when a robbery at a small grocery store changes in an impossible way before his eyes — and he realizes the change came from within him — an ordinary life is no longer an option. There’s a game unfolding in the shadows of the city, and the pieces are real Tarot cards with actual power. Someone is collecting all of them. Kaito doesn’t know who, doesn’t know how, and doesn’t know what will happen when the collection is complete. But one thing became clear that night: he is already in the game. He just doesn’t know what it is. What will you find in the story? Ascension and Evolution: Follow Kaito’s growth within a system. From a young man who only sought to escape routine to a player who must master the rules and become the strongest. Fate vs. Free Will: An exploration of how much control we truly have over our lives, or if we are merely pieces moved by greater forces and "cards" already dealt. Intellectual Duels: Brute force is nothing without strategy. Expect complex mind games and battles where cunning and the interpretation of rules are the greatest weapons. Unique Combat: When dialogue fails and the cards are revealed, realism gives way to intense, supernatural confrontations that alter the world around them. Connections and Romance: Amidst the chaos of the game, human bonds will be tested. The development of deep relationships and the emergence of romance in future chapters bring layers of vulnerability to the protagonist.
