Lu Mingfei arrives at Cassell College convinced this is a scam, and the show spends no time convincing him otherwise, it just drops him into a world where dragons are real and he's catastrophically unprepared. Hiroyuki Sawano's soundtrack doesn't just accompany the action sequences; it transforms them into something that feels weightier than the animation budget alone could deliver. Every fight is animated with a kind of brutal precision that makes even his failures feel earned rather than pathetic.

Lu Mingfei is an average high school student about to graduate, satisfied with modest achievements and proud mainly of his skill at StarCraft. Everything changes when he receives a scholarship and an acceptance letter from Cassell College in Chicago, a school he never applied to. Convinced it must be a scam, he eventually accepts anyway. Once there, he learns the college exists to protect humanity from dragons. Drawn into this long-running conflict, Lu begins to uncover the grim truth behind humanity's war with the dragon race, and sets out on his own path toward becoming a king, finding friendship, love and growth along the way. Adapted from the novels by Jiang Nan, this ONA blends action, drama and fantasy.
