The newcomer, Derrick, hails from the isolated City of Silver—a place shrouded in darkness and plagued by countless dangers. Through Derrick’s story, Klein uncovers the tragic history of the forgotten city. Hoping to save his homeland, Derrick places his faith in the enigmatic Fool, who welcomes him into the Tarot Club under the title of The Sun.
Meanwhile, another challenge arises when Alger, known as The Hanged Man, proposes a mission to eliminate the notorious pirate admiral Zilingus. To gather the intelligence needed, Audrey, Justice, uses her noble status and vast network of connections, joining forces with the mysterious Beyonders Fors and Xio. As the investigation deepens, hidden conspiracies and dangerous enemies begin to emerge from the shadows.
With guidance from his mentor, Azik, Klein carefully orchestrates events behind the scenes, allowing the members of the Tarot Club to combine their unique talents in pursuit of a common goal.
