Trajectories: The Royal Family Blacklisted by the World

Other people transmigrate and get a System from the start. He transmigrates and blows things up. Bad news: He arrived too late, and the story's already over. Worse news: This world seems to hate him. His orbment breaks down every few days, his luck is awful, and even monsters chase him down to bite him. Worst of all, the Empire's Crown Prince comes knocking: "You, go be a babysitter for a class." Kai: ??? But I'm royalty too! After Kai starts school, Kai: ? You didn't say this was a class full of problem children! But then he watches these problem children start showing off divine powers. Kai: ????? Wait, what? Who's the one with the problem here? Tch! I never should have listened to that guy and gotten on that train! (This is the story of someone rejected by the world, who ultimately gets the world to entrust its future to him.)
