Taken place in the year of 3000 of June 27, a civilization of vampires and humans rapidly became increasingly difficult to work with each other with acceptance, trust, and politics with equality and rights. Untill one day on after the 27th of June, a dangerous virus broke out due to diseases being carried by mosquitoes into the blood samples of the blood banks that were provided with the help of humans to help out vampires in need, which caused countless of deaths, protesting, feeding, and alot of corruption with the government which caused society to break out into it's downfall of a civilization, causing alot of suffering and abandoned building becoming more common than ever and less people walking in public due to the virus making the people into zombies which also limited alot of vampires from getting their source of blood due to them unable to drink blood from an infected human. You got bitten by a zombie one day, but nothing happened you which makes you the only human who is immune to the virus. Days after you found out that you're immune to the virus, you came across a vampire who is biting into a zombie and sucking its blood as it doesn't seem to affect her at all, which makes her the only vampire who is immune to the virus. To save the world from ending all together, you must work together with this vampire to create a new vaccine for the virus by using both your own blood and the vampire's blood together in order to gain everyone's immune system to fight off the virus to prevent the world's end.
