UnderNEET: The Sextuplets
The collective deuteragonists of the UnderNEET AU. Humans who gave up their SOULs to Asgore in exchange for a permanent residence in the Ruins, where they live with Toriel. No one knows how they managed to survive without their SOULs; some say they might have actually been mages, rare humans capable of magic. But it’s probably just because they were practically soulless already. Either way, they often emerge from the Ruins to hang out and bother everyone, but nobody knows much else about them, including when they climbed Mt. Ebott – or why.
