Ep. 17: Imusa seeks Hinge Stones while Yoruba attacks GAUS crew and Mirasa lies about Muetta
Efy Dolgh soldier Imusa returns to Earth to locate the three remaining Hinge Stones, including the Keystone. Meanwhile, the GAUS crew awaits replacement parts and debates whether Muetta is Princess Yukihime. Kennosuke employs the Black Relic to search for Muetta. Efy Dolgh soldier Yoruba travels to Japan in the Bluebird geoframe to check on comrades and shoots down the transport plane carrying the GAUS parts. The crew offloads the cargo before crash-landing into a dam, where Kennosuke uses the Black Relic to save the plane and passengers. Yoruba finds Mirasa, who lies about Muetta’s fate, prompting him to search for her. He encounters the Black Relic and attacks, but the Demon attaches his flying geoframe to the relic to aid Kennosuke. Due to Kennosuke’s mistrust, the Demon departs but promises future assistance if needed.
