Touma is visited by a man from the Sword of Logos, Rintaro Shindo, who has come to relieve him of his SworDriver and Brave Dragon Wonder Ride Book. When Touma refuses to give them up, Rintaro takes him to his organization's headquarters to debrief him on the conflict he has become involved in. Touma now faces the choice of whether to use his power as Kamen Rider Saber to save people and the world, or stay out of it.

Despite Ryo defeating the Hanzaki Megid, the place it attacked did not return to normal and Sora is still missing. In response, Touma and the other members of the Sword of Logos look for a way to rescue him.
