* DramaticUnmask: After Sento and Gentoku defeat Utsumi, the second Build appears before them and dismisses his transformation, revealing himself to be [[spoiler: Shinobu Katsuragi, Sento's father.]]

* WhamShot: [[spoiler: Not only is there another Kamen Rider Build, but his identity is Shinobu Katsuragi!]]

->'''Sento''': In order to take over the nation, the extraterrestrial entity Evolt has begun gathering 10 Lost Bottles, extracted from ten powerful monsters, the Lost Smashes.
-->Kamen Rider Build AKA Kiryuu Sento is searching for his father, Shinobu, creator of the bottles...

->'''Sento''': And that's enough of that.
-->Look, things have been going crazy while you guys were occupied.
-->So pay attention, before we get into Episode 42.

Sento’s father, Shinobu Katsuragi, is alive and is working alongside Evolto! This information is starting to greatly worry the Build team, as it seems that Shinobu’s mission is to collect all of the Lost Bottles and add them to the black Pandora Panel and there is the possibility that Shinobu could be the one who is pulling the strings. Sento believes in the righteous purpose of the system that his father developed, but in midst of the action, another Build appears.

** Ryuga doles one out to Utsumi after witnessing Evolt's Black Hole Finish from the bridge, moving faster and hitting hard than he has ever done before as Cross-Z Magma.

** The second Build causes a SmokeOut with [=NinninComic=] and ambushes Ryuga and Kazumi, disappearing after the smoke fades away with Ryuga, as his only target, falling over in pain.
