A being known as Zaeranite fought against others in an attempt to rule the universe. They were able to thwart his plans for the time being but he would rise again. The battle had left our unknown saviours near death. Still, they were able to send what power they had left to Earth to help those who could stand up against his reign. Over the course of mankind, their powers took the form of gems that are able to increase their possers ki many times over. The keepers of the gems where able to search one another out. When the time came that the gems are needed, the past keepers started a dojo that prepared potential user to be ready.
In the distant future, Zaeranite threatens Earth with his minons that come from the darkness of space. The dojo you ask? Well, it's still in the very spot where it was founded, though it's a far cry from what it once was. Now, sitting on the corner of Destiny Ave and Hope St as a run down studio dojo with its name too worn and faded to be legible.
You just so happen upon this dojo.
