"Yet the Criminal Dances with the Dragons") is a Japanese light novel series, written by Labo Asai and illustrated by Miyagi, who was later replaced by Zain.

[2] A manga adaptation of the original series with art by Yaku Haibara was serialized in Kadokawa's Beans Ace magazine.

A long time ago, dragons were the only creatures capable of wielding magic, which they used to terrorize humanity, until humanity learned to channel magic through special formulas and spells called "jushiiki".

Those capable of using jushiiki became known as jushikiists, and became crucial in fighting dragons throughout the years, until a peace treaty was enforced to prevent both races from wiping each other out.

In the modern day, Gayus and Gigina are two jushikiists who take special jobs from a variety of clients in the city of Eridana.
