Quinn crosses into a strange world with wraiths. He enters SS-Rank Anomaly Instances like Blood Moon High School and the Time Train. With intellect and skills, he sees through rules and dodges traps. He befriends Ethan Chan, tames Heidi, and fights villain wraiths from the Sakura Dominion, Vengeful Wraiths, and instance bosses. Quinn overcomes trials, clears the instance, averts disaster for the Cathay Republic, and brings Susan back for a peaceful, happy conclusion.
