#BlackCat #vampire #deadly #sins Gwen is the sin of greed hence the tatoo on her hands, Miriam is the sin of jelousy hence tatoo of demon on one arm showing she's double sided. Nine is their cat- sewn together from a white and black cat, she's named nine becuase in chinese the word nine sounds similar to another word in their language meaning torture or suffering so 9 is bad luck.. like a black cat.
