Baron Lemon Energy Arms and Knuckle cannot hold off Demushu forever, and he escapes them. With Sid murdered at the hands of Rosyuo, he instructs Redyue to continue the invasion of Zawame much to Takatora's shock and terror, while Mitsuzane seeks out the Fruit of Wisdom still. Elsewhere, Kouta wakes up, and DJ Sagara presents him with something that will help him out.
- Fake Shemp: Due to Ryoma Sengoku's actor, Tsunenori Aoki, taking some time off of filming Gaim to act in a musical, Ryoma only appears transformed in this episode and the previous one with Aoki merely providing Kamen Rider Duke's voice.
- Mythology Gag:
- In order to use the Kiwami Arms, Kouta must first transform into Kachidoki Arms. This is just like Agito, who needs to transform into Burning Form first before into Shining Form. In addition, the transformation involves Kouta's armor ejecting parts off of itself, just like Kabuto's Cast Off.
- After receiving the Kiwami Lockseed, Kouta falls against a cabinet which bears images of playing cards (in particular a Joker card). Given that the conversation proceeding this has DJ Sagara saying Kouta must become an Overlord, this is a fairly obvious nod to Blade, the climax of which had its hero becoming a Joker Undead.
- Wham Episode: Gaim gets Kiwami Arms, Redyue launches a full-scale invasion, turning Zawame into a war zone cut off from the outside world.
- Wham Line To save the world, Sagara gives us this:DJ Sagara: So really, there's only one solution. You have to become an Overlord yourself.
