Riko, a young Red Whistle trainee in Orth, searches the Abyss’s first layer for relics with Nat. When they become separated, Riko finds Nat threatened by a crimson splitjaw and draws the predator toward herself with her whistle. Cornered and unable to escape, she is saved when an unknown blast drives the creature away and melts nearby petrified trees. Tracing the attack, Riko discovers an unconscious boy whose body appears mechanical. She and Nat secretly carry him back to Belchero Orphanage, where Riko hides him from the adults and recruits Shiggy and Kiyui to help revive him. Their improvised electrical treatment causes a blackout but awakens the stranger, who can speak yet remembers neither his name nor his origin. Riko identifies his unusual body, extending arms, and resistance to heat as signs that he is a robot. She names him Reg after a dog she once owned. Escaping the orphanage’s scrutiny, Riko takes Reg outside at sunrise, shows him Orth and the enormous pit below, and proposes that he climbed from the still-unknown bottom of the Abyss.
