Kamen Rider's Original Sequel

The name of the protagonist knight "Build" means "creation, formation", which is also consistent with the protagonist's identity - a young genius physicist, and he is also the protagonist with the highest IQ in the history of the Heisei knights. The protagonist's transformation prop is an "experimental reagent bottle" commonly used by scientific researchers, and the battle is like a scientific experiment. And from the protagonist's catchphrase "Come, let's start the experiment" and "The law of victory has been decided!", It can be seen that physical experiments and laws are a major clue in this game. On the other hand, the director also claimed that the scale of the world view of this work is the largest in history-involving the entire Japanese archipelago. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
