This series tells the story of a team of ancient heroes protecting the world from ominous forces. Throughout history, the unicorn symbolized virtue and seemed to ensure the rule of goodness. When our heroes wake up too early, they find themselves in the bodies of teenagers. As a result, their memories of themselves and the history of unicorns over the centuries have been destroyed, and some of their magical powers have been weakened and fragmented. They should not only protect the world from widespread darkness, but also do so in the face of unexpected laughter and humor brought about by teenagers' anxieties and emotions.
