Akihiko Miyoshi, an easy-going college student, is called by a cute princess one day. He is called by the sword and magic fantasy world Arsphere. The princess says, "Pull out the sacred sword and subdue the Demon King."

There was an important secret hidden in the sword that would determine how the Arsphere should be. He would use the power of the sword, and if he wanted to, he would be able to rule the world. However, Akihiko is on a journey to cross the world with the mighty power he has been given, to defeat evil, and to improve himself. However, I am surprised that Princess Riomi, who loves himself, has come with him.
