Sunset Shimmer appeared on earth in a pocket dimension that was created by the Phantoms with no memory and the power to transform into Kamen Rider Symbol.

She meets another Kamen Rider called Dante but something is familiar about him. Like her, he has no memory of his past.

The two journey together to try and find out how and what they are.

This will be in the style of a Hack and Slash game with a lot of focus on fighting and not so much focus on the plot.
