Histoire
When two people die at the same time, they’re sent to a place that’s neither heaven nor hell—a lavish bar between worlds where the stakes are high and the rules are simple: if you win you live again, if you die… you’re gone for good. Decim is the bartender charged with serving the souls who enter Quindecim. He may make a mean cocktail, but his true profession is to play the role of arbiter—a judge who determines whether or not a soul is worthy of reincarnation.
