An empty room, nothing but darkness from all directions. In the middle of the room, standing on a wooden podium, shows an open book as someone reads its contexts. ???-Kamen Riders... Heroes who fought against threats towards humanity. They become Beacons of Hope for those who can't fight and for those who are in need of a savior. However, there are worlds out there who don't have a Hero known as Kamen Rider. A world where a new threat towards Humanity has appeared in a world, similar to ours, this threat is known as Noise. Beings who cannot be harmed by normal means. All Humanity can do is run and hide from this unkillable threat. But Fear not! As witnessing such events and seeing what these monsters can do! Hearing the pleads of all, a new hero has been born! Iwae! The one who shall inherit the powers of all Riders! For the new King of Time and King of all Riders has been born!

In the world of Heroes meet 3 Quirk less individuals who have the power of the Kamen Riders and show them the means to be a hero that save the world from the darkness that is lurking under their feet. Who are these three and why do they fight? Is it because it's their goal/dream to become a hero or is it something more to them?
