Yumeria moves so fast you don't have time to notice the plot barely exists. The comedy lands harder than it has any right to, the art pops in ways most 2004 shows don't even attempt, and Tomokazu actually feels like a person instead of a harem vacuum. It's a show that knows exactly what it is for exactly twelve episodes, then stops.
On his sixteenth birthday, Tomokazu Mikuri has a vivid dream of a girl fighting a huge floating monster. When he wakes, that same girl is asleep beside him. From then on, every time he sleeps he returns to the dream world, and more and more people he knows begin turning up there. A masked woman named Silk tells him they are fighting an adversary called Faydoom, and that he is the one who gives the girls the power to battle these monsters. The show mixes action with comedy and ecchi across twelve episodes.
