This article is about a/an episode in Kamen Rider Build.
Red alert WARNING: This episode contains scenes of blood, murder and character deaths. Viewer discretion is advised!

Zero Degree Flames (ゼロ度の炎 Zero-do no Honō) is the forty-seventh episode of Kamen Rider Build. It features the return of the Engine Bro's and Remocon Bro's as imitations made by Evolto and the full debut of Grease Blizzard after its brief appearance at the end of the previous episode. It also features the deaths of Kazumi Sawatari and Nariaki Utsumi, the latter of whom was revealed to be a cyborg.


Grease has transformed into Grease Blizzard using the Blizzard Knuckle despite Sento warning him not to do so as it would mean the end of Kazumi’s life. Kazumi decides to burnout his soulfire with the remaining spirit of the Hokuto Trio within him for the last time. And the one person to witness his end… is Misora…
