Kẻ Thù Virus

"The Kẻ Thù Virus infects only grownups at the ages of sixteen and beyond if they don't comply to the rouge ducanger regime of the Republic of South Vietnam, if they don't vaccinate real soon, or if they don't keep their immune system high. Well, at least it's limited, and I hope I wasn't the last uninfected grownup in here."

--Su Ji-Hoon, My Enemy is Their Enemy
