Reserve

On the way to a date, Mio falls into a hole to another dimension. Eager to return before she misses her much-anticipated date, an elf fairy tells her the only way back is through the forest ahead, which crawls with monsters who have never seen a human before. Mio is given a set of powerful spheres to use as weapons and sets off to return to the real world, unaware of the monsters' true intentions.
