Ultraman R/B Novel: The Blue-Eyed Girl Whose Name is Gray
The Alien Egon Ciel (シーレ Shīre) was a criminal who wished to obtain the rare minerals buried under the Zarra Tribe's desert in Planet Gion. The Interstellar Alliance sent down Rosso, Blu and Grigio to take care of the alien criminal. Ciel piloted the second Barrigator to eradicate the fleeing Zarra Tribesmen while the other model was left to fight Ultraman Rosso and Ultraman Blu. After seeing the Zarra Tribesmen bravely fighting against Ciel's Barrigator, Grigio was given the R/B Crystal that allowed her to transform into Grigio Regina and fight back against Ciel. As Regina was winning and his Barrigator started to lose, Ciel try to escape in an escape pod, but Regina incinerated the alien into dust.
- The novel suggest no dialogue from Ciel's appearance.
- Ciel's role in the novel is a retread of Mr. Largo, a similar criminal who also wanted to excavate rare minerals within a certain planet and attempted to commit genocide towards an entire tribe to obtain it. Whereas Largo made it out scot-free due to his affiliation with the already-corrupt Alliance, Ciel's crime is made known by the group and is given approval for apprehension.
