Even in the prosperous lands of Legoria, there are those who needlessly seek the thrill of adventure. 

Natsuki and Yuki left their hometown to do just that, but before they can even complete their first mission as adventurers...
"We greet the Saint."
Natsuki's demonlike horns draw the attention of not only the Church...
"Are those horns real ivory?"
— but also the feds!

Join Natsuki and Yuki on their journey to travel the world, to see all kinds of monsters and magic, and— to keep out of the hands of all the people coveting Natsuki's priceless horns.
