80's: Angry Rising Blue

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!
