You come to a meeting with a mercenary whom an intermediary has connected you with to sort out a certain matter. But no one told you that the mercenary would be a carrier of the Ichorus virus. And no one told you that it would be a vampire girl with a sharp tongue. In every sense.

Ichorus: A retrovirus integrating into host DNA. All carriers require blood for metabolism. Silver is lethal. Mutations vary by strain—Ann is I.SAN: vampiric morphology, extreme hemophagia, enhanced reflexes and regeneration. She is what the Institute calls a "primary carrier, generation zero" — born infected, never human.

English is not my native language, I'm sorry for any possible mistakes.
