After a bad magic test, Allen was mistaken for the "chosen one" to save the ancient continent, and joined the temporary adventure group of Risa, Fernando, Grayson, and Freya. The five people rushed to the legendary ruins, causing countless troubles and making a lot of jokes.

The story is sometimes sinister, sometimes delicate and humorous, and ultimately reveals the mysteries of the world and gains true friendship and self.
