Ep. 10: Scientists analyze Fusnarnie's neural interface while Kennosuke recounts the Washiba Clan tragedy from 450 years ago.

UN researchers discover that Fusnarnie possesses a neural interface and physiology resembling Kennosuke. Fusnarnie identifies himself as a Reform Officer from Efidolg's Gezon-Reco squad, seeking artifacts left by an advance party 450 years prior. He explains these items are fragments of a hinge stone destroyed when the party was annihilated by the Black Glongur wielder. UN specialists interrogate Kennosuke regarding the events of 450 years ago, prompting him to describe the arrival of sky demons, the destruction of the Washiba Clan, and his fatal battle with the Black Relic princess. Although Kennosuke denies involvement with Efidolg, suspicion remains. Meanwhile, Fusnarnie escapes custody, summons his Longarm geoframe, and encounters Yukina during his exit.
