When the Weird invades Blue Star, people are constantly being transported to other parallel weird worlds to challenge the Weird. It is said that as long as seven strange sources are collected, there is a way to eliminate the strange invasion of Blue Star. Blue Star countries urgently launched defense plans and selected talented young people from various countries for training to become "war guardians" against the strange. But unfortunately, no one has been able to pass the level and obtain the source of weirdness so far.
