The technology, artifact, or supernatural force that creates Kamen Rider MY-TH remains a major mystery. Who created it, and what was its original purpose? If it was designed specifically for combat, there could be an earlier war or experiment that explains why it exists.

There is also the possibility that the system was never intended to be used by humans. Its unusual abilities could suggest that its creators understood powers or forces that modern characters barely comprehend. Discovering its origin could completely change how the Riders understand their own powers.
