Finally: it's the moment we've all been waiting for. What's the deal with all the teeth?
"Brimstone was a resurrectionist" (49.7).
Huh?
We learn about Brimstone through the story of Madrigal's sister Chiro's death... and rebirth.
Somehow, dude is able to create a new body for a dead chimaera by making a necklace of teeth and gemstones. Madrigal was the lucky gal who got to make her sister's necklace.
The resurrected are called revenants, and they have hamsas—the eye tattoos on their palms, just like Karou has.
Oh.
That purity talk from before? It has nothing to do with virginity.
It means you haven't died and been resurrected. (Yet.)
Anyway, after all this backstory, we're back to Madrigal fretting about a dance.
She decides it's time to take a bath and think things over.
