Dead Unicorn Trope: The myth that all Sentai Yellows love curry, lampshaded when Yumeria orders four bowls of curry, Hiroyo tells her not to overdo it, reminding her that only two (Daita Oiwa and Asao Hyo) had it as their Trademark Favorite Food.
Hand Signals: Used by the fake Deka Red to give his message to Nobuo, as he was actually a man in a suit hired by Hiroyo and as such couldn't speak, he eventually resorts to giving Nobuo the same drop kick Ban used to snap Hoji out of it in Dekaranger.
Heroic BSoD: Nobuo goes through one after finding out that the team's battle from the previous episode was just a delusion. He snaps out of it thanks to "Deka Red" (actually someone in a Deka Red suit).
New Powers as the Plot Demands: The Akibarangers are deluded enough to cause the Machine Itassher to transform (but not enough for a cool battle with it yet); Nobuo is deluded enough for Deka Red to appear to help fight and give them the penultimate power of the Dekarangers, the Deka Cuffs, wielded by Akiba Red.
10-Minute Retirement: Nobuo, after Hiroyo revealed to him that his adventures as an Akibaranger is merely a delusion, until he is snapped out of it by a drop kick from Deka Red (actually a man in a suit hired by Hiroyo). Nobuo notes that that was the same drop kick Ban used to snap Hoji out of it in Dekaranger.
Vocal Dissonance: Yumeria's "true" voice when she loses her cosplay ears.
