A student who failed the college entrance examination was admitted to a somewhat strange university; a young lady from a mysterious family came to this university because of certain responsibilities; a girl who hid a secret was recommended to study at the university; a wandering orphan came here voluntarily after being adopted; a boy who survived a disaster accidentally awakened and found his kind here. As time passes, weirdness gradually arises. Strange changes have occurred all over the world. Where did these changes come from? How should they, who are just starting out, deal with this huge conspiracy that is gradually emerging? Although their original intentions were different, they all came together in the end and became companions along the way. They faced these difficulties together and let's see if they can penetrate these fogs and protect everything they care about.
