Kouta and Kaito work together to try to find Yuya, but they instead face off against an even more terrible enemy.
- Comes Great Responsibility: Kouta learns this here.
- Curb-Stomp Battle: Gaim receives his first one of the series courtesy of Zangetsu.
- Deconstruction: Kouta loses a fight with Zangetsu, and nearly dies. While normal toku would vow to defeat Zangetsu, Kouta becomes petrified to the point of not even touching his belt.
- Family-Unfriendly Violence: Zangetsu's No-Holds-Barred Beatdown of Kouta.
- Mythology Gag: Kouta settles his transformation pose on something similar to Kamen Rider Fourze and Space Sheriff Gavan, while Ryugen is the one mimicking Kamen Rider Super-1.
- As if acknowledging his namesake, Kaito Kumon grabs a whole bunch of Lock Seeds before leaving the world of Helheim.
