freezing king

shujin fukumuto is the reluctant future king of time he doesn't understand why this power was given to him and to make matters worse he is seen as the best weapon against the novas with no explanation as to why he doesn't even know how powerful he really is

disclaimer i will be using the ridewatches like how its done in the story 'ridewatch hero' but with my own twist the ridewatches activate the drivers that the MC uses for instance say he activates the kiva watch then kivat will appear and he will transform as if he was kamen rider kiva or if he activates the zi-o watch the ziku driver would appear on his waist and he would then transform think kamen rider ghost for the different drivers
