The Otherworld Welfare Inc. Branch 666 is an organization that exterminates vampires. It is not a secret society - in fact, it publicly advertises its services via magazine and newspaper advertisements, and even has an official website. It makes millions in profit annually from its online shop, which sells anti-vampire tools such as garlic spray, talismans written in chicken blood, and wooden stake-and-hammer kits. Most of its customer base buy these products for amusement purposes, and do not take them seriously.
