The End of Humanity

Its 2037, a new virus has become a major problem for the past 10 years. Most of the entire population of the world has died due to it. Most places where humans would have been are now surrounded and taken by nature and animals. There are few survivors left, but they would kill each other just to survive. This virus kills in 24 hours, will AI and the others be able to survive?

AI is a 15 year old white male, maybe about 5'11", who has dark brown hair with olive green eyes. Who lived in Italy when the outbreak had happened. AI has always been a loner and enjoyed weapons. AI is willing to kill anyone he meets just to survive. He decided to find a way to travel around the globe, maybe finding people to kill. (other characters will be introduced later into the story)
