Yumeria

On his 16th birthday, Tomokazu Mikuri has an unusually vivid dream: a girl is locked in combat with a massive, floating creature. When he wakes, the shock continues—she’s somehow asleep right beside him, turning a “dream” into something far harder to dismiss.

From then on, every time Tomokazu falls asleep, he’s pulled back into the same dream realm, and familiar faces begin appearing there as well. Guided by a masked woman named Silk, he learns they’re battling an enemy called Faydoom—and that Tomokazu plays a crucial role, supplying the power the girls need to fight the monsters that threaten that world.
