In the vast universe, humans have limited knowledge of dimensions. There are other advanced dimensional worlds outside the dimensions known to humans. In the material dimension, the dark dimension camp wants to occupy more dimensional space to expand its territory, while the light dimension protects other dimensions and fights with them. On Earth, their last battlefield, the light dimension reduced itself and the dark dimension to a plane. The dimensional spirits of the two camps also stayed on Earth. Only a few humans who have the power to unlock the dimension can transform the dimensional spirit from a plane back to a three-dimensional one. They are called "dimensional generals."
