Shake the Hands

Nagaoka reveals that he had planned their battle by sending the Houjo siblings and Kodama to fight him, trying to intimidate Tazuna and Koyori. Undeterred, Tazuna summons their gears and Koyori turns into a fairy; Nagaoka changes into a flowery coat along with Mayumi. The battle ensues, and Mayumi conjures brightly-coloured cocoons that rebound around physical objects, turning anything it touches into a flowery patch of ground. Nagaoka then causes the area to explode. At first, Koyori and Tazuna try to fall back, but are caught in the explosions as many cocoons rush after them. As they flee, Tazuna asks Koyori if she feels alright fighting her older sister, to which Koyori explains that she is able to connect to everyone she comes into contact with, which means she can also do the same with Mayumi. Emotionless like the old Koyori, Mayumi attacks everything in sight as they face off with Nagaoka. A formidable opponent, he can destroy their gears and Tazuna and Koyori are at a losing end. Tazuna then realises that Mayumi cannot fight without destroying her Nimrod, and if she pushes herself too much she will disappear and die. Nagaoka does not relent, and they use Mayumi's exhaustion as an opening to attack him repeatedly. Luring him up to a skyscraper unwisely, Mayumi places all her cocoons under it and set off dozens of explosions. In a desperate attempt, Tazuna and Koyori link hands and fight as one, defeating Nagaoka. The battle is not over yet as Mayumi persists, and is revealed to be able to speak, her first words being that she will protect Nagaoka even is it means her disappearance. At that, Koyori connects with Mayumi, her former partner, and stops the disappearance. Returning to the real world, Nagaoka makes amends with Makihara. Mayumi explains her emotions occurred when she bonded with Nagaoka and like Koyori, she can connect with the people she comes into contact with. Complimenting Tazuna, Nagaoka leaves with Mayumi, who wants to eat a parfait with him. K
