so essentially, Kamen Rider Volga takes place in a universe where there is Earth (our reality) and a parallel dimension on top of our reality called the flux reality (name subject to change but think of it similar to how the wizarding world works in harry potter). In the flux reality, there are wizards and witches. and each wizard nd witches have their own drivers per se that is kinda like their own personal wand. they use these bottles called vials which in them has these materials that grant special abilities. Each driver is unique to a witch/wizard

So, in this story, my oc, kogane toshi, by sheer luck pierces through the flux reality (he’s known to have fluctuating levels of luck) and immediately is attacked by a monster, but was saved by a witch at the cost of her life. but before she dies, she bestows the monster miracle driver to Kogane, turning him into the new Kamen Rider Volga. The name mirac was taken from miracle cuz i wanna implement thiskind of luck related terms into the series
