At the school's coming-of-age summoning, Fred Carter unexpectedly calls two beasts: an A-rank Blazing Dragon and an F-rank Shadow Cat. Classmates and Rhea, a top student who had been close to Fred, accuse him of tampering and claim the dragon as theirs. Teachers expel Fred for seizing another's beast, and Rhea publicly dumps him — 'You're beneath me now.' Amid humiliation, his God-tier Beast Master System detects his mood swings, activates, and issues the beginner mission Break up with Rhea, promising a millionfold upgrade to the Shadow Cat. Fred is expelled and must face that sudden mission.
