Long ago, people lived in a world that was full of magical energy called Growshu. Using the Growshu floating in the air, the people could cast magic spells, and they made their living. However, their sun was becoming a dying star and their land was doomed to decay. To save their world, the humans and Featherians had to cooperate and they were successful in superposing their world into another world. As a result of this, the magical energy Growshu was lost, and humans could only cast magic using the scarce Growshu leaking from the distortions between the two worlds. Only people called Growsians can potentially wield powerful magic like in ancient times. Winged people called Featherians also exist, though they live in seclusion from humans.
Eventually, on this continent there were three countries. Rolandia kingdom in the west and its neighboring country Burnschtein jointly created the Magic Academy to mutually gather knowledge and put magic to use.
Carmaine is a young man living in the capital of the kingdom of Rolandia. Rolandia's palace magician, Lady Sandra, had taken him in as a young orphan and raised him. He was prophesied to become a "threat to destroy the world" or the "light which saves the world" when he was found as a baby. Uneasy about his future, Sandra did not show him outside the capital or let him have contact with the outside world. She did all she could to show him the proper way to live. Then, on the morning he turned seventeen years old, she told him the day has come for him to set off and choose his own path. He goes off to explore the world and see it with his own eyes, accompanied by a fairy-like homunculus named Tippi which Sandra created.
In Carmaine's questing, he becomes an officer for the King. With this job he must carry out missions to help his country. There are mysteries surfacing and trouble brewing as various enemies seek to disturb the land and people.
