Nago offers his resignation to Shima, but Shima refuses, granting him access to IXA’s Rising upgrade as he feels Nago has accepted his own weaknesses. However, the celebration is short-lived when Megumi and Shima are arrested. Nago is informed by the senior officer responsible that his former dealings with the Blue Sky Group 22 years prior led him to be injured by IXA, and in order to save his colleagues, Jiro appears and grants Nago access to Castle Doran’s Time Door, sending him back to 1986 and bringing him face-to-face with Otoya!

Still in 1986, Nago tries to explain to Tanahashi that he’s from the future and trying to change history, but Tanahashi believes he’s lying. After Nago attempts to throw Otoya off by kidnapping Yuri, Maya saves him and asks about human love, and while Nago can’t explain it directly, he gives her the button from his first bounty, calling it a good luck charm. Later, when the events leading to Tanahashi’s injury begin to unfold, Nago changes the future and vanishes, but upon his return, after assisting Kiva, he discovers that Wataru holds the very button he gave Maya! But why does Wataru have it?
