(Kamen Rider Cross-Z X Kill la Kill)
After being defeated by Kamen Rider Cross-Z, Killbus managed to let a fragment of himself escape. He used that fragment to enter and begin reshaping another reality this time, the world of Kill la Kill. While traveling through that world, Kaito Daiki, a.k.a. Kamen Rider Diend, discovered Killbus's presence and the threat he posed. Realizing the danger, Kaito searched for someone capable of protecting the world.
Enter Y/n Banjo, the son of the original Kamen Rider Cross-Z. Kaito gave Y/n a mission: to serve as a Secondary Rider in this new world and stop Killbus before it's too late. With a Ridewatch in hand and the weight of his legacy on his shoulders, Y/n accepted the mission. From that day forward, his journey as the successor of Cross-Z began right in the heart of the Kill la Kill world.
