Kamen Rider: Humanity First, Starting with Kabuto

After putting an end to the ambitions of the Crisis Empire, Kotaro Minami sets out on a journey to protect the world on his own. By chance, he encounters a mysterious screen of light and transmigrates to the world of Kamen Rider Kabuto. Destroying every Another is how we protect humanity. An Another is an Another. Even if it takes human form, it will never become human. The meaning of being human isn't defined by memory. My body may be battered and broken, but my human will won't waver. I acknowledge your will, and so I acknowledge your right to die as a human. The Kabuto world, the Zecter world, the 555 world... Every world where Anothers exist welcomes their strictest father.
