Sento Kiryuu

Sento Kiryuu, also known as Kamen Rider Build, is the titular main protagonist from the Kamen Rider Build series.
== Charactah Account ==
Sento is a self-proclaimed handsome and brilliant theoretical physicist suffering from amnesia that made him forget the last 20 years of his life. He transforms into Kamen Rider Build in order to fight the Smash and learn the truth about himself. His genius mind enables him to create Build and Cross-Z's equipment.
Originally a man with no memories of his past, one of the greatest traits Sento has kept from the transition from Takumi is his genius-level intellect, which he has displayed numerous times with his advanced knowledge of science, mathematics, engineering, and cryptography. Sento is easily attracted to anything he deems mysterious or interesting, such as a new innovation or a lead towards uncovering his past, and will relentlessly pursue it. This will continue until either he reaches a conclusion or someone forcibly stops him during progress. When Sento gets excited (usually due to a discovery or breakthrough), he receives an ahoge, a single lock of hair that typically represents a person with a foolish and carefree personality, traits that are not entirely absent in Sento.
Another trait that is carried over from Takumi is his polymathism, which is accompanied by an inflated ego and sharp tongue: Sento likes to praise himself for his works, and often mocks Banjo for his comparatively lower intelligence. Sento often relies on his own skills to solve problems and never expects sudden assistance from others, so when it happens, he tends to either be surprised or turns them down. Also, Sento can be easily caught off guard when he accomplishes anything or witnesses something unexpected and new which excites him, because of his reliance on his intellect. In this state, he is vulnerable to any surprise attacks.

== Trivia ==
* In Toei's attempt to bring the franchise back to its roots, Sento's character history involving his imprisonment and experimentation on by Faust is a callback to the Shocker experimentation origins of the Showa Era Riders.
* As revealed by Atsuhiro Inukai, Sento's habit of playing Monster Hunter with friends at night caused him to appear worn and haggard when filming Kamen Rider Build, with it being used to portray Sento's gradual fatigue facing Faust.
* Despite Sento being a physicist, he is mostly seen doing chemistry in the show, such as when he created the RabbitTank Sparkling Fullbottle by extracting the Nebula gas from the Rabbit and Tank Fullbottles using a process similar to distillation. He has also displayed skills in engineering as seen with the creation of his many weapons created for his Best Match forms.
