Enredo

After death, humans go to either heaven or hell. But for some, at the instant of their death, they arrive at the Quindecim, a bar attended by the mysterious white-haired Decim.

After death, humans are either reincarnated or sent to the void. Before this happens, they arrive at the Quindecim, a bar attended by the mysterious white-haired Decim. In order to fairly judge them, he has them play a Game, wherein they reveal their true nature. Decim himself is the arbiter of who wins and who loses.—Shakti Prasanna Mishra

A happy married couple lands by two separate elevators in a bar where the bartender explain them that they have to play a game in order to keep their life. Later they discover the true horror of the meaning of their presence in this very place.—Pel Par

When humans die they go to either heaven or hell; but when two people die in the same instant a judgement must be made as to which soul goes on to be reincarnated and which goes to the void. When this happens, the humans arrive, with no memories of their death, at QuinDecim a bar attended by the white-haired bartender Decim (pronounced Dek-imm). They must then play a game in which their true natures are revealed so that Decim, an arbiter of souls, can make his judgement on where their souls are headed.—Kate Midgley

Humans who die are either sent to heaven or hell, but a select few are sent to a bar called the Quindecim, where they play twisted games to determine their fate, all the while recalling the pieces of their lives that contributed to where they ended up.
