Now Depart for the Front Line! Kachidoki Arms!

is the twenty-third episode of Kamen Rider Gaim. It features the debut of Gaim Kachidoki Arms, as well as the proper debut of Demushu, the first of the Over Lord Inves.
==Synopsis==
Now aware that he killed Yuya, Kouta loses all will to fight, and will not even seek to destroy the Scalar System. As he struggles with the thought of telling the truth to his friends, Kaito encounters the strange Inves in Helheim Forest, once more.
==Plot==
Devastated upon learning the truth about Yuya, Kouta loses all will to fight, and Mitsuzane suggests to him not to tell anything about it to their friends. Meanwhile, Ryoma discusses the mission he gave to Kaito with his allies, which is to get more information about the "Over Lords", which are human intelligence Inves who have managed to evolve and adapt to the Helheim Forest, claiming that it is the path mankind should follow to avoid extinction. As Kaito finally encounters and confronts the Over Lord Inves he has been looking for, who attempts to introduce himself to Kaito as Dēmushu, Kouta meets Mai in the place where they would have met with Yuya when he last contacted them, and he refrains from telling her the truth as Mitsuzane suggested.
Back at Drupers, Kouta has another vision of the mysterious girl who supports his decision to stop fighting. Soon after, DJ Sagara appears before him, claiming that instead of just sacrificing others, there are others who pursue their dreams by fighting their way without renouncing anything, just like Kaito, and he presents Kouta with the Kachidoki Lockseed and a Dandeliner Lockseed. With his will renewed, Kouta mounts the Dandeliner and launches an attack on the Yggdrasill Corporation headquarters. A team of Kurokage Troopers are dispatched to stop him, but there is little they can do to stop Armored Rider Gaim's new form, Kachidoki Arms, and are defeated by his varied attacks through the Hinawadaidai-DJ-Ju. Takatora appears to confront him as Zangetsu Shin, but fails to stop Gaim from destroying the Scalar System.
Gaim then flees, after declaring that with their contigency plan destroyed, the Yggdrasill Corporation has no option but to find a way to stop the Helheim Forest's invasion. The mysterious girl reprimands DJ Sagara for interfering with Kouta's decision, but he points out that she also did the same, as in the end, all that matters is who will be the one to be chosen by the Helheim Forest. Enraged with the recent developments, Ryoma contacts Mitsuzane and instructs him to investigate Kouta in order to find out who betrayed the Yggdrasill Corporation and is assisting him.
