The Strongest Power! Kiwami Arms

The Strongest Power! Kiwami Arms! (最強の力！極アームズ) is the thirty-second episode of Kamen Rider Gaim. It is the debut appearance of Kamen Rider Gaim Kiwami Arms.

Synopsis
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.

Plot
Baron Lemon Energy Arms and Knuckle confront Demushu with Marika watching as Kurokage Troopers intervene. Eventually, Demushu tires of its opponents and leaves. In Helheim Forest, after gaining Rosyuo's permission to travel to Zawame with an army of Inves, Redyue informs Mitsuzane of Sid's death while revealing his own intention to conquer Earth and become its ruler. From there, Redyue reopens the Crack at the Yggdrasill Corporation headquarters to take over the building while its Inves army makes its way outside. Elsewhere, no longer able to conceal their activities from the public, the forces of the Yggdrasill Corporation make patrols around Zawame to find Demushu while incinerating any Inves that they encounter. Marika asks for backup from Ryoma, but he evacuates in a rocket from the headquarters as it is overrun by the Helheim vines, leaving her to rely on Zawame's remaining Beat Riders, Baron, Knuckle, Gridon, and Bravo, who join her in battle to drive off the Inves. Elsewhere, though in pain as he regains consciousness, Kouta is still horrified by Demushu's ideals as Sagara appears to him and Mai. Sagara heals his injuries and explains to the livid youth that he never said that the Over Lords would help them, and further explains that the only way to save his world is to become an Over Lord himself. Sagara adds that Kouta must be willing to kill off any rivals to obtain the Fruit of Knowledge. Against Mai's pleas, Kouta agrees and Sagara reveals the Lockseed he previously obtained from Rosyuo while freezing time. Sagara explains that he wants to ensure this power to a wild card, and Kouta fights against the frozen time to take the Kiwami Lockseed to show he wants the means to the end. Once he manages to move himself to grab the Kiwami Lockseed, Sagara disappears and Kouta and Mai are freed from his lock. Though the Beat Riders have had the advantage against the numerous Inves, they are defeated by Demushu after he surfaces from the sewers, having replenished itself on the Helheim fruits growing within them. Just as it is about to deliver a finishing blow on the group, Kouta arrives and becomes Gaim Kachidoki Arms to fight Demushu before using the Kiwami Lockseed to combine all of the other armors to transform into Armored Rider Gaim Kiwami Arms. Now able to use the weapons of all of the other Armored Riders, Gaim overpowers Demushu before destroying it with apparent ease.
