**COMPLETED** In the land of Opuree, a vast, divisive community has been built across thousands of floating islands, with the infamous Soulbell Prison at the nation’s foot. Revered for its unbreakable confinement, Soulbell harbors the most dangerous criminals. After being imprisoned for a crime he didn't commit, a brash young man named Mateo finds himself trapped within the prison’s towering stone walls, but he quickly learns that there's far more going on behind closed doors than he could’ve ever imagined. In a rare turn of events, the prison has offered inmates a chance to earn their freedom back through “The Iris Games”— a series of intense, lethal one-on-one duels where each inmate is able to utilize a unique, powerful ability they’ve awakened within them. In the event where a prisoner collects ten duel victories, that inmate earns their freedom, a prize that these criminals are willing to do anything to obtain. In order to return home, Mateo must navigate the perilous Iris Games and unravel the truth behind the deaths of his loved ones. But along the way, Mateo faces many obstacles and hardships, and finds himself getting lost in his motivations.  Is he really fighting to see his family again? Or is there something else that's propelling Mateo’s desire to win?
