“Harvey wasn’t interested in the clothes, it was the masks that mesmerized him. They were like snowflakes: no two alike. Some were made of wood and of plastic; some of straw and cloth and papier-mâché. Some were as bright as parrots, others as pale as parchment. Some were so grotesque he was certain they’d been carved by crazy people; others so perfect they looked like the death masks of angels. There were masks of clowns and foxes, masks like skulls decorated with real teeth, and one with carved flames instead of hair.”
― Clive Barker, The Thief of Always
(I love that in Latin larva can mean either mask or the wandering spirits of the dead. There’s just something so right about that.)

Puts a new explaination of a character from Vampire Princess Miyu. There is a character called “Larva” who wears a mask and wears long dark robes.

How interesting! I would imagine that’s intentional.
Relatedly, I saw a manga series called Alichino that sounded rather interesting, though not interesting enough for me to pick up.
