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.

Odd Jobs Arataka
A freelancer business run by Reigen Arataka based out of a former cafe. It also serves as the base and hideout for Kamen Rider Build, housing a basement laboratory that focuses on Fullbottle purification and the development of gear and gadgetry that uses the Fullbottles.

Izuku Midoriya
The main protagonist, a 18-year old freeter who found a job at Odd Jobs Arataka upon being able to become Kamen Rider Build. While he initially became Build in order to fulfill a childhood dream of becoming a hero, numerous revelations regarding his allies lead him to expanding his focus on learning the truth behind his father's disappearance.

Senku Ishigami
The deuteragonist, a 25-year old genius theoretical physicist suffering from amnesia that made him forget the last 25 years of his life, the only remaining link being his experimentation at the hands of Faust. He works with Izuku in order to fight the Smash and figure out the truth behind himself, with his genius allowing him to produce equipment for Build to use in combat against the Smash.

Reigen Arataka
Izuku's boss, a 28-year old con-man who excels in persuasion, speech and perception, as well as boasting a surprising amount of knowledge regarding physics and science. He also seems to know more about the Smash and Faust than he lets on.

Mash Kyrielight
A 16-year old teenage girl who yields mysterious powers that allow her to purify Smash essences into Fullbottles. She almost never leaves the lab in Odd Jobs' basement, but in her spare time she makes web videos under the guise of an Internet idol, calling in her viewers to send in tips to aid Build.

Mayumi Saegusa
A 25-year old investigative reporter who seeks to uncover the mysteries behind the Smash and Kamen Rider Build. While she may act professional during her job, she has a habit of teasing people.

Katsuki Bakugou
An 18-year old criminal who was once a promising prize fighter before accusations of cheating led to his disqualification. He was convicted of having murdered Tatsuya Shiba, a scientist who had been doing research on the Pandora Box. Like Senku, he was experimented on before he managed to escape captivity and found refuge with his old childhood friend Izuku. He accompanies Senku and Izuku to investigate the mystery behind Tatsuya's murder, arguing all the way.

He eventually obtains the ability to become Kamen Rider Cross-Z, using the Cross-Z Dragon as an add-on for the Build Driver in order to do so.
