Kamen Rider Decade: Riding the winds of worlds

15 years have passed since Kadoya Tsukasa died at the hands of Ohma Zi-o, but what if... he didn't truly die? After awakening in a new world, Tsukasa found himself face to face with a boy, one who's expression he was all to familiar with.

Taking the boy with him due to his troubling circumstances, Tsukasa returned to his home at the Hikari Studio, taking the boy under his wing, guiding him so that he wouldn't go down the same dark road he went down years ago.

Present day, the boy, freshly graduated from high school, now works at the Hikari Studio, his way of repaying Tsukasa and his friends. But everything changes when monsters attack, and he learns the reason behind him being taken in by the destroyer of worlds.

Connect everything by destroying everything, as the new passing through destroyer.
