Data xx Transitory is the thirteenth and bonus episode of the DRAMAtical Murder animation. It features all of the bad endings from the original game.

Some time ago, the influential and powerful Toue Inc. bought the island of Midorijima, Japan, with the plans of building Platinum Jail—a luxurious utopian facility. Those who are lucky enough to call it home are the wealthiest citizens in the world. The original residents of the island, however, were forced to relocate to the Old Residential District; and after the completion of Platinum Jail, they were completely abandoned. "Rib" and "Rhyme" are the most common games played on the island. Rib is an old school game in which gangs engage in turf wars against each other, while Rhyme is a technologically advanced game wherein participants fight in a virtual reality. To be able to play Rhyme, you must have an "All-Mate" (an AI that typically looks like a pet), and the match must be mediated by an "Usui." Aoba Seragaki has no interest in playing either game; he prefers to live a peaceful life with his grandmother and All-Mate, Ren. However, after getting forcefully dragged into a dangerous Rhyme match and hearing rumors about disappearing Rib players, all of Aoba's hopes of living a normal life are completely abolished.

After reincarnating from her previous life as an office worker and avid gamer, Lilia Carol grew and gained friends in her new world. During her fifth birthday, she met the handsome Elk von Luxel, who left her entranced. She normally has no issue maintaining her composure, but his presence manages to distract Lilia from her usual magic practice. As their paths continue to cross, a friendship blooms between them.

Fable, an assassin who works in organized crime, has been raised to the legendary status of a ruthless killer capable of murdering any man within six seconds. Six years after his debut, his boss fears that Fable has started to attract too much attention from the legal authorities, and he orders him to hide in Osaka for a year. Accompanied by his driver who assumes the identity of his sister, Fable is bound by a special condition: he must act as a civilian and not murder anyone lest he and his partner lose their lives. However, the seemingly well-deserved holiday soon takes a grim turn. Takeshi Ebihara, the second-in-command of the Osaka mafia that officially protects the assassin, sees Fable's presence as a threat and wants to remove him. Constantly monitored by the yakuza and regularly put in life-or-death situations, Fable has no other choice but to outwit Takeshi's schemes if he wants to stay alive.
