Kamen Rider Build: Build the Hero

Kamen Rider Build: Build the Hero is an upcoming fanfic remake of the 28th Kamen Rider installment, Kamen Rider Build.

Synopsis
Ten years ago, Japan launched Project Providence: the first successful expedition to Mars. To add to the success of the expedition, the astronauts brought back with them proof of extraterrestrial life on the red planet - a strange cube with unknown properties that had been found in ancient ruins. This artifact held the potential for a possible source of clean energy. With this incredible asset in their hands, all signs pointed to a possible technological revolution for Japan.

However, something went wrong when a mysterious man barged in and attempted to touch the box during the celebration of the expedition. Despite the best efforts of security, the man managed to reach out and touch the box, which triggered it's activation and caused a massive structure called the Skywall to rise, dividing Japan into three separate pieces. To compound matters even further, the people present at the event were warped by the energies of the cube itself, increasing their inherent aggression and splitting the already divided Japan into three states: Touto, Seito and Hokuto.

Each state has their own governments and doctrines, but all desire the massive power of the box - dubbed the "Pandora Box" - for themselves. As the Prime Minister of Touto was not present at the event, possession of the Pandora Box fell onto Touto itself.

Now, a new crisis has struck the region as human-like monsters known as the "Smash" attack innocent civilians at random. While the government is refusing to address the topic at hand, a hero has been hunting down the beasts. Unbeknownst to all, the identity of the hero is a young freeter known as Izuku Midoriya, who has taken up the role in hopes of finding clues regarding his father's disappearance. Now, as he searches for clues about his father, he uses the Build Driver to become Kamen Rider Build in order to do battle with the Smash and Faust, the organization behind these monsters.

But he is not alone in this fight, for he is supported by Reigen Arataka: a con-man who runs an odd jobs business, Senku Ishigami: an amnesiac genius physicist who seeks to reclaim his lost memories, and Mash Kyrielight: a teenage girl who possesses powers that let her purify the Smash essences into the Fullbottles, the very source of Build's powers.
