- Anyone Can Die: Solidified when Ryoji is killed and it's revealed that Yuya was the Byakko Inves that was destroyed back in #1.
- Bad Guys Do the Dirty Work: When Kouta begins to sweat over killing Hase and trying in vain to get him to become a human again, the New Generation Riders come in to finish off Hase and spare Kouta the turmoil and instead give him a person to hate.
- Big "NO!": Kouta, when Sid kills Hase in his monster form.
- Deconstruction: A villainous Kamen Rider unsympathetically kills a person who has transformed into a monster. Revealing himself to be Sid, he mockingly answers to the shocked and outraged protagonist:"'Why?' Seems fairly obvious to me. I destroyed a monster that was attacking our citizens. I'd say that's pretty heroic."
- Four Is Death: The four New Generation Riders.
- Funny Background Event: Slacker waitress, Iyo, draws and brandishes a broom when Ryoji turns Inves and attacks the fruit bar.
- Ironic Echo Cut: Kouta screams "I can't kill a human!" when he's confronting with an Inves-transformed Ryoji Hase. Cut to the next scene where Micchy notes, "Yuya (who was the Byakko Inves from episode 1)...was killed by Kouta."
- Missed the Call: Confirms one fans had long suspected: Yuya was Sid's original choice for Team Gaim's Sengoku Driver, but ended up eating a Lock Fruit and changing into an Inves. His abandoned Driver was the one Kouta and Mai found in #1.
- Mythology Gag: When Sigurd detransforms after killing a monster, he held his hat in a similar manner to how Shotaro holds his hat, further illustrating that what he did was no different to what Kamen Riders do.
- Psycho Rangers: This episode establishes the New Generation Riders as this..
- Wham Episode: Urobuchi, who wasn't kidding about what he said, seriously warned that this episode would put kids off orange juice. He was right. In the previous episode, Hase had turned into an Inves, and unlike humans-turned-monsters from other Rider series, he isn't saved: the New Generation Riders debut and Hase is killed by Kamen Rider Sigurd, who is revealed to be Sid. Worse, we find out that the Inves from back in #1 was in fact Team Gaim's missing leader Yuya, meaning that Kouta had unknowingly killed one of his close friends.
- Wham Shot: Yuya in the Helheim Forest, eating the Lockseed that would make him the Byakko Inves.
- Wham Line See Deconstruction
- What Measure Is a Non-Human?: Deconstructed by Sigurd, who was asked why he killed an Inves that used to be human, claiming that what he did was justice.
