The End of Evolto

is the forty-fourth episode of Kamen Rider Build. It features the debut of the Blizzard Knuckle.
==Synopsis==
Kazumi and Gentoku start to infiltrate Faust’s Hokuto headquarters with different intentions than Sento and the others have. It seems that they are following the path that leads straight to Evolto. However, MadRogue and his army quickly discovered their location and proceeded to surround them. Meanwhile, Shinobu once again transforms before Sento and the others after tracking them down as he intends to take them in for experimentation as well. “You were useless after all. It’s because of you humanity will be destroyed!” Sento refuses to acknowledge his father’s words as strong feelings of frustration begin to stir within him…

*As the title of the episode suggests, this episode features a supposedly final boss fight that seemingly ended too easily (with said boss returning later on), and involves the father of a character. A very similar setup happens just one series ago in Kamen Rider Ex-Aid, in the exact same abandoned field area.
