Reg is attacked by a Turbinid-Dragon. Gaburoon rescues him and escorts him back to the village. During the journey Reg learns that Gaburoon is a “Interference Unit,” a “robots capable of independent thought and actions.” These units seek to observe and gather knowledge. There was one unit placed in each layer and they cannot cross layers, however, they can share information with each other. According to Gaburoon they haven’t shared information in a long time, meaning the other units are either broken or taken. Reg isn’t one of these units, but Gaburoon wonders if they share a creator. That said, Gaburoon doesn’t know who his creator is and ask Reg to find out who created them.
Moogie officially introduces Riko to one of the Three Sages, Wazukyan. Riko becomes embarrassed at not properly introducing herself to such an important being. Wazukyan doesn’t seem phased and gives her a “high five” and leaves. The Narehate teaches Riko some basic Narehate language. Moogie explains that their language has “lots of words in which many actions and names are stuck together.” For example, Iruburu, the name of the village, means 50% “village,” 40% “cradle,” and 10% “mother.” Riko quickly learns the basics.
Later Riko heads to a cave in the village called Dogupu (Within the Eye). While there she encounters an imprisoned woman, Vuelo Eluko. She was an opponent of establishing the village which she claims had terrible “origins.” She was imprisoned. However, her opinion apparently has changed after observing the village. Riko frees her without hesitation, claiming she doesn’t care if she’s a “bad person,” or not she just wants to see her friends. In the village, Vuelo (in disguise) and Riko head to Belaf. Riko sees Nanachi laying next to “Mitty.” After meeting Belaf, it is revealed that Mitty is a clone that Belaf got it by sacrificing “half its body, 724 limbs, and a portion of its sensory organs” from Bondrewd.
Finally, Belaf reveals that Nanachi sold themself to buy Mitty and if Riko wants them back she’ll have to sell parts of her body. The Narehate in the village have made it clear that they convent the body of a human child. I speculated that the “perverse obsession with Riko’s body” would result in a sacrifice. Belaf asks for Riko’s eyes, legs, or “half her innards.” As dark as Made in Abyss can get, I don’t think it will have Riko sacrifice that much. Faputa, Gaburoon, and Vuelo all have some opposition to the village, so Reg, Riko, and Nanachi might join forces to escape, especially if the Narehate can’t leave the village.
