The Next Kamen Rider Ex-Aid [Male Reader and Original Character x Crossover]

Forty-five years ago, multiple different worlds combined and form a new version of Earth. This world is filled with humans, Faunus, Terrans with powers called Quirks, Semblances, and Arts. There are also cyborgs known as Constructs and Nikkes that are stronger and more powerful than normal people. Man made vampires known as revenants. Humans with Mana and magic known as Hunters.

There are also many threats, from super powered villains, a robotic alien race known as Raptures, Magic Beast that want to kill everything that isn't them, machines called Corrupted that attack anything near them, bloodthirsty mutated Revenants known as Lost, crystalized titans that kill anyone in the containment zones, and creatures of darkness called Grimm.

Y/N L/N is the next Kamen Rider Ex-Aid, after his grandfather, the original Ex-Aid, passed down his Kamen Rider Gashat and Driver to Y/N to fight the new age of monsters. Y/N is about to start his journey at the most prestigious school in the world, Union University. The same school his older half-brother Robert Shade went to and dropped out off. Robert has helped Y/N train for this event and still supports his younger brother to succeed where he failed years ago.

The next game is about to begin, one where Y/N will change the world and finish what started decades ago. One that involves his life as a Kamen Rider and the lives of the other Kamen Riders as well as the fate of the world.
