"A Mistant," Tyki said, looking over his shoulder at Szayel, who had been the one to ask. "Where we're from, they wear identification tags, so that's what they're called."

They, he said. Before being taken into the Noah Clan, after spending enough years living rough on the streets of Undelwalt, that would have been 'we'. Fortunately for him, he made enough of a fuss out there to be picked up by those who shared his genetic mutation, and so he was raised in relative comfort, without the tags that had been hung on his neck from childhood.

It was pretty liberating, being able to walk around, looking like he did, without having to wear a tag. The Noah weren't the only ones who enjoyed the benefit of not needing to wear a tag when they looked or behaved very differently to the rest of the population. The von Überwalds, de Magpyrs and others also had the same freedom from limiting trinkets.
