Have you heard of Jigoku Tsuushin (Hell Correspondence)? Those with a powerful grudge may only access this mysterious website at midnight, allowing them to enter anyone's name and have that person be ferried straight to hell. Ai Enma, the Hell Girl, will not judge whether or not the chosen target deserves punishment; she will merely exact revenge on them for you, provided your pain or suffering move her. Not much is known about this young girl other than that she swiftly carries out her tasks with the help of three straw dolls. There is just one catch, however—as payment for carrying out such a request, the user must condemn themselves to an afterlife in hell. [Written by MAL Rewrite]

After death, there is no heaven or hell, only a bar that stands between reincarnation and oblivion. There the attendant will, one after another, challenge pairs of the recently deceased to a random game in which their fate of either ascending into reincarnation or falling into the void will be wagered. Whether it's bowling, darts, air hockey, or anything in between, each person's true nature will be revealed in a ghastly parade of death and memories, dancing to the whims of the bar's master. Welcome to Quindecim, where Decim, arbiter of the afterlife, awaits! Death Parade expands upon the original one-shot intended to train young animators. It follows yet more people receiving judgment—until a strange, black-haired guest causes Decim to begin questioning his own rulings. (Source: MAL Rewrite)
