Sicarius 13

Sicarius... a group of serial killers that existed in the society for years, but suddenly disappeared.

They are the vampires of the world that can linger through night and day, only asking for bloodshed.

The wolves, deceiving humans into cute house dogs only to be devoured by their greed after.

The snakes who only knew betrayals and poisons.

And the demons that can coexist with humans.

A group of wanted killers consisting of 12 members... or so they thought.
