A huge space monster appeared in a city and began to destroy the city. People were escaping with screaming. Among them, there were five high school students, En, Kai, Shin, Yoku, and Ryu. However, they failed to escape, and they rushed into a patrol car parked nearby. The monster was approaching to them. When they began to accept their death, the patrol car glowed blue white and disappeared into a mysterious space carrying them. (myanimelist.net)
