Cat-girl nun and serial killer who went mad, sided with a demon, and had to be put down.
Sister Ines was a nun who was, in Quasar's words, "actually like a serial killer lady" — and, delightfully for the retelling, a cat girl, which is exactly why Princess Donut could not stand her.
On the eighth floor she went insane, though Quasar notes there is "some question on how it happened" — the mechanism was never satisfactorily explained even to the viewing public. By the end she was working with Amayon, the Sheol demon who arrived in the world during a demon eviction event, and it fell to Louis to put her down. Killing her had consequences that outlived her: Louis was marked for death by the god Ysalte, sponsored by the Nebulars, for the deed.
A cat-girl nun — feline features on a woman in religious habit, a combination the recap treats as inherently funny.
The eighth floor's mad nun, whose death by Louis's hand triggered a god's death-mark on him.
