The Severing Best Match (離れ離れのベストマッチ Hanarebanare no Besuto Matchi) is the thirty-fourth episode of Kamen Rider Build. It features the debut of Evol Dragon Form. It also features the possession of Ryuga Banjo by Evolto and the truth behind the murder of Takumi Katsuragi.


Kamen Rider Evol was born, and the first victim of his power was Taizan Himuro, the prime minister of Touto! Evolto now engages a full-scale onslaught to complete the Pandora Box, and his next target is Sento. Evolto infects Sento with an alien poison that can only be cured by Evolto. Because of this, Sento’s life is on a deadline as he demands the remaining Fullbottles and the Pandora Box in exchange for Sento’s life. Just what will the remaining Riders do now?!

  • This episode reveals that there was a Gorilla Fullbottle prior the creation of the one seen in the series, explaining why Takumi Katsuragi was able to transform into Kamen Rider Build GorillaMond in Kamen Rider Ex-Aid: True Ending and Ex-Aid's 44th episode before the Gorilla Fullbottle was created by Sento.
    • This also reveals that a Fullbottle can be turned back into an Empty Bottle.
  • Sento Kiryu briefly dies in this episode before the removal of the poison revived him. As with the mid-30 episode-count of a typical Heisei Phase 2 series, the protagonist usually dies before coming back with their final form.
  • After Cross-Z and Evol's final attack before it resulted in an explosion, only Ryuga's body was seen intact on-screen with Evolto now in possession of his body, while the fate of Soichi Isurugi's body is later shown in the next episode.
  • This is the first episode since it's debut that Build does not assume his TankTank Form.
