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 goes off to explore the world, accompanied by a fairy-like homunculus named Tippi. In this world, magical energy called Growshu fills the air, and people called Growsians can potentially wield powerful magic like in ancient times. Carmaine's younger sister Louise is one such Growsian. Winged people called Featherians also exist, though they live in seclusion from humans. Long ago though, humans and Featherians had to cooperate to save their world. 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.

Four countries are getting involved in a war, and people have forgotten that they were on the verge of destruction by the hands of malevolent angels two thousand years before. They are now again descending upon the world to punish humanity. In the middle of this, a young man named Crevaniel, who was raised as a mercenary, witnesses a dark-hearted seraphim flying through the sky. Knowing that it is a sign that the angels are returning to oppress humanity, he sets out to battle the angels for the sake of the world.
