An ancient dragon attacks, leaving him alive with a mysterious scar, and unable to use magic the way everyone expected. With Princess Richeria at his side, Itsuki must learn how this new world really works, uncover what the dragon left inside him, and find his own way to save the kingdom that summoned him.
