Created by "Ya Ren" Miura Juan Nuo and "Hot Blood Battle", the bloody and crazy death game cartoon "Sky invasion" finally launched the animation adaptation! Senior high school students travel to the city and find themselves lost in the "abnormal space". Here, countless skyscrapers are connected by suspension bridges, and "masked men" mercilessly kill confused and fleeing victims. If you want to get out of such purgatory alive, you have only two choices: to kill the masked man, or to die. She decided to try her best to survive in order to destroy this perverse world. What is her ultimate fate?
