Protagonist Leonardo Watch is a young photographer who travels to Hellsalem’s Lot to help his ailing sister before being given the “All-Seeing Eyes of God” by a mysterious entity, an incredibly powerful prime artifact which gives him the power to see the past and future, see through others’ eyes, and more. His powers catch the attention of Libra, and he joins the group to keep the city safe together with its members which include Klaus Von Reinherz, the leader of Libra and master of the Brain Grid blood fighting style which he uses to create large weaponry and seal away enemies; Zapp Renfro, Leanardo’s partner in Libra and Master of the Big Dipper blood fighting style which allows him to manipulate his blood into weapons and explosives; Chain Sumeragi, A suit-clad werewolf who has the power of invisibility and can move at high speed, making her best suited for most of Libra’s reconnaissance work; Steven Starphase, Libra’s second-in-command and master of the Esmerelda Blood Freeze fighting style that freezes enemies on contact; K.K., a lively member who fights with high-powered guns that electrocute enemies; Deldro Brody & Dog Hummer, two men sharing one body who are only called upon by Libra in dire situations and are kept sealed away in the most secure part of Hellsalem’s Lot’s largest prison; Zed O'Brien, a merman who uses the Shinatobe branch of the Big Dipper blood fighting style to generate tridents and threads from his blood; Gilbert Altstein, Klaus’ brother and the main intelligence gatherer for Libra who looks like a mummy due to his face being covered with bandages and has the power of regeneration; and Blitz Abrams aka “Lucky Abrams,” Klaus’ mentor and a famous vampire hunter who has somehow never been harmed by the curses placed on him by enemies over the years.
