A mysterious item is delivered to paranormal investigators SSP. SSP members Naomi, Jetta and Shin determine that it is a transformation device... the X Devizer that housed Ultraman X both during and after his merging with Xio agent Daichi Oozora (Kensuke Takahashi). Gai Kurenai (Hideo Ishiguro), the human form of Ultraman Orb returns from his wanderings to search for X ... unaware that this is just the first sign of a new threat to the Earth. The villainous space witch Murnau has allied with Ultraman Orb's arch enemy Jugglus Juggler to use the Dark Ring she now possesses.
