A world where mages have gained great power in place of swordsmen due to the "magical revolution" that occurred about 10 years ago.
Glenn, a skilled swordsman who was even hailed as a "sword master," was affected by this, and was now barely able to make ends meet through his hired work.
One day, as Glenn heads home after finishing his work, he comes across a group of young magician apprentices bullying an ugly lizard-like spirit.
Glenn, who saved the spirit with his once proud sword skills, names the lizard "Juju" and begins living with it.
Then, Glenn's life begins to change...
This is the story of Glenn, the former strongest swordsman, Juju, a spirit with the power of the highest class "Sacred Dragon," and his friends.
