Heilei

The Heilei (黒雷 Heirei) is a assassin guild with ties to the Shinoyama Group.

Background
The guild is made up of members of the Lei Family (雷家 Rei-ke) who are an old family of contract killers mostly based out in cities such as Shanghai, Hong Kong and Yokohama. They were a prominent guild of assassins that specialized in poisons. Though they were forced to adapt and move away from their old ways of primitive poisons and adopt new technology for their work. The latest technology they receive is supplied by the Shinoyama Group which created a unique and strong partnership.

In the Heilei the members of the guild do not consider themselves "human", be they a child or parent, all regard themselves as objects, tools that can be replaced. They do not mourn for crippled members of their kin, instead seek to utilize them to further arts as showing pity or mercy towards them would be neglecting their trade.

Despite progressing towards the use of modern methods, the Heilei still practice their traditional arts albeit their more ethically questionable ones. One being the T'ing-Fu (庭壺 Tinfū) which means "Garden Pot" which basically is a vessel that the clan uses to cultivate bacteria to make poison. The vessel in question that is used normally is a young child, which they could designate to be a family if they have no use for.

Trivia
