The mission to enter the City to kill the Vampire Prince and all the other Vampires is not just from the Awakened Association but even the government and the World Awakened Organization.
After all, this is the very first outbreak in history and is being watched by every country. Some nations sent aid using their Artifacts, some sent monetary assistance, and some sent their country's S-Rank Awakened to help in this disaster.
This is why the president of the republic wanted this Outbreak to be settled as soon as possible. It is not a secret that the president will reward the people who would greatly contribute to saving the civilians and the elimination of the Vampires.
Aside from that, Vanessa also knows something that not even the S-Rank group she sent away is aware of… and that is the President's concern about this Outbreak.
Apparently, his daughter is still inside one of the shelters underground in the city.
