About chapter 45, the woman wasn't one of the 3 sages but still one of the people involved with the creation of the village, but apparently opposed it at the end and ended up in that prison-like place. So I wasn't too far off about her, she was
almost one of the sages.
Then the part with Nanachi. I had expected Maji Kajya to be evil, but he was very apologetic about leading Nanachi there. Still, never expected that this Mitty isn't a fake but the real one. And it's also confirmed Bondrewd visited the 6th layer several times. Interesting how the village can reproduce anything completely faithfully, even the soul. Isn't the village a god in a sense then?
Knowing how dark this series can get.. would Riko really give out both eyes, both legs or half of her internal organs? Would be a pretty awful sight to stomach...
It wouldn't kill her, but it's still really extreme. And I don't see her getting Nanachi back in any other way, unless they brute-force it with Reg. Out of these she may pick half her internal organs, since the other are invaluable for her to continue. Reg should be back in the village soon, maybe he arrives in time to stop her? Because I also don't see Riko just walking out on Nanachi and Mitty.
But, since the village is so almighty, even if Riko loses her eyes/legs she could get them back perfectly reproduced later.
