Mur Mur stops the apocalypse dead and just talks to you. The animation shifts into stop-motion and sketches and whatever else feels right for the joke, treating the goddess of time like a character instead of a narrative device. You get to watch her be genuinely funny and small and human in ways the main series never lets her, which means you walk back into the bloodshed with a different read on who she actually is.
Mirai Nikki: Ura Mirai Nikki gathers the short Mur Mur segments that were attached to the ends of the main Mirai Nikki episodes. These ten brief episodes went unaired and were released on the Mirai Nikki Blu-rays instead. They blend comedy and action with the mystery, psychological and supernatural elements of the franchise, and they serve as bonus material for viewers of the main series.
