Kamen Rider Build

is a Japanese tokusatsu drama and the 28th entry of Toei Company's ''Kamen Rider'' metaseries. It is the nineteenth series to debut during the Heisei era. The show premiered on September 3, 2017, following the finale of ''Kamen Rider Ex-Aid'', joining ''Uchu Sentai Kyuranger'' and later, ''Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger'' in the Super Hero Time line-up.

Summary

A cataclysmic event involving an artifact of an ancient Martian civilization has created a supernatural barrier called the ''Skywall'' which separates Japan into three territories, Touto, Hokuto, and Seito. Along with creating a complex power dynamic between the three regions, the event brings waves of monsters called ''Smash'' down on the country, who terrorize and attack the citizens.

The protagonist, Sento Kiryu, is an amnesiac taken in by a mysterious cafe owner named Soichi Isurugi who provides him with a belt called the ''Build Driver'' that allows him to turn into Kamen Rider Build, which he uses to fight the Smash on his own. Build has different powers determined by the combination of a pair of ''Fullbottles'' inserted into the belt, each containing the essences of organic and inorganic matters. Full bottles are obtained by defeating the Smash and absorbing their essence into a Fullbottle and then purifying it.

Throughout the story, Sento learns that his forgotten past is connected to the events of the Skywall Catastrophe, that the Smash is the work of a larger organization attempting to rule the world, and that his allies are not what they seem. In his search for the truth about his past and a solution to the crisis, Sento makes several allies who also gain the ability to transform and fight with him, encounters several nemeses who brutally push back at his attempts to save humanity, and is forced to question who is on what side, and what the sides even are.

Production

The Kamen Rider Build trademark was registered by Toei on May 18, 2017. A press conference was later held on August 1, 2017 to reveal the cast and crew, plot details, the suit and bike of Kamen Rider Build. A trailer was also shown and later released on Youtube later that same day.

Suit design

The motif of Kamen Rider Build's main form was "rabbit" and "tank". The motif of the form was suggested by Takahito Omori, who found the combination interesting.

One of the villains, Night Rogue, has their suit recolored for Kamen Rider MadRogue, which appeared from episode 38 onwards.

The monsters of the series is called "Smash". They were designed in a way so that their motif are not immediately obvious in order to surprise the audiences when their essence was captured by the main characters after their defeat.

Episodes

Similar to the previous series, half of each episode's title is an English word, though spelled in katakana instead of English letters, and the other is written in kanji. Also, each episode briefly shows mathematics and/or physics formulas, which forms the episode number.

Every episode of the series were written by Shogo Muto.
