One night, Madoka has a terrible nightmare – against the backdrop of a desolate landscape, she watches a magical girl battle a terrifying creature, and lose. The next day, the teen's dream becomes reality when the girl – Homura – arrives at Mitakihara Middle School as a transfer student, mysteriously warning Madoka to stay just the way she is. But when she and her best friend Miki are pulled into a twisted illusion world and meet a magical creature named Kyubey, the pair discovers that magical girls are real, and what's more, they can choose to become one. All they must do is sign a contract with Kyubey and agree to fight witches that spread despair to the human world, and in return they will be granted a single wish. However, as Homura's omen suggests, there's far more to becoming a magical girl than Madoka and Miki realize...
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. To aid in his judgment, the bar's patrons are forced to play simple games laced with sadistic twists designed to bring their true natures to light. To Decim, judgment has always been black and white - that is until he meets a mysterious young woman whose fate seems impossible to decide. His indecision shakes the very foundation of the games and raises the biggest question of all: who is fit to judge the dead?
