After his encounter with Faputa Reg is not only lost, but being tenaciously pursued by a turbinid-dragon, who is able to read his moves and even chip his metal arm. Reg is rescued by a fellow robot—AKA “Interference Unit”—who gives him a ride home.
The unit doesn’t know why Reg was built, only that it’s unheard of for units to ever cross layers, and that he’d prefer if Reg left as soon as possible, as he worries he could lead to the ruin of this delicate place. He honestly might not be wrong!
After briefly meeting Wazukyan, who seems friendly if a bit spacey, Riko takes the opportunity to learn the basics of the Hollow language from the bilingual proprietor of the canteen. Being a child, Riko picks it up pretty fast. She learns, for instance, that the name of the village, “Iruburu”, means 50% “village”, 40% “cradle”, and 10% “mother”.
Her language teacher also directs her to Doguupu, AKA “within the eye”, a place at the edge of the village where Hollows can’t go, but non-hollows like Reg and Nanachi might. Riko and Maaa head there, descend into a pit of sticky mud…and encounter Vueloeluko, AKA Vueko.
Riko is astonished to find another human, but Vueko is so out of it she’s initially not sure if she even is human. After all, can a human really live the 1,900 years since they found the island where Orth would one day be built? The fact she’s restrained by several tendrils also suggests to Riko she’s a “bad person”, and Vueko can’t really deny that.
She tells Riko a tale of how the origins of Iruburu “aren’t very nice”, and she was blinded by greed wanting to become somethng beyond human. So she leads her quiet dreary existence in this mud pit, naming the hollows who enact the “balancing”, singing, and basically just straight chillin’.
She also says that however awful its beginnings were, the village is now a relatively peaceful place full of children who lost their human bodies but whose souls remain carrying on. But bottom line, Riko wants to find her friends, so she frees Vueko, brings her up to the village, and gets her some clothes.
Vueko leads them to Belaf’s cave, but doesn’t go in there with them; clearly there was a falling-out between them and the present Belaf would probably prefer if Vueko stayed imprisoned in black goo forever. Belaf doesn’t threaten Riko—indeed, he’s in awe of a human child in this place—but he doesn’t spare her the weight of the present situation.
Nanachi is there, but they’re unconscious, put to sleep by “smoke”, as a distraught Majikaja puts it. He had no idea how important Mitty was to Nanachi, you see, so could not have predicted this would be the end of Nanachi’s journey. When Nanachi saw Belaf eating Mitty (who can be eaten infinitely and not die, but simply remains forevermore), they “sold” themself in exchange for Belaf giving him Mitty.
Riko recognizes Mitty and stares her in the eye like the time, and credits Mitty and her haunting eye in particular with saving her life when she was in a very bad way medically. Since this is a place of buying, selling, and negotiation, Riko asks Belaf what she’d have to offer in exchange for Nanachi and Mitty.
At first Belaf says he wants her entire body, but Riko reminds him how tremendously valuable she is in this place. Unfortunately, his final offer is for her to choose which of three things to give him that will satisfy him: both her eyes, both her legs, or half of her innards. Let’s just say I do not envy Riko’s predicament. I can’t help but think force (i.e. Reg) will be needed to free Nanachi…but then, do they even want to be “freed”, or are they free already?
