The start of Hanae Ashiya's high school career has not been easy—he has spent all of the first week in the infirmary, and his inexplicable condition is only getting worse. The cause of his torment is the mysterious fuzzy creature that has attached itself to him ever since he stumbled upon it the day before school began. As his health continues to decline and the creature grows in size, Hanae comes across a flyer advertising an exorcist who expels youkai. Desperate and with nothing left to lose, he calls the number and is led to the Mononokean, a tea room which suddenly appears next to the infirmary. A morose-sounding man, Haruitsuki Abeno, reluctantly helps Hanae but demands payment afterward. Much to Hanae's dismay, he cannot afford the fee and must become an employee at the Mononokean to work off his debt. And to make things worse, his new boss is actually one of his classmates. If Hanae ever hopes to settle his debt, he must work together with Abeno to guide a variety of dangerous, strange, and interesting youkai back to the Underworld. [Written by MAL Rewrite]

Said to be humanity's natural enemy, formidable dragons that belong to an ancient bloodline roam the world. Only two ways prove effective to kill a dragon: freezing their blood with silverine—an aura that comes from silver weapons—or letting their bodies be incinerated by sunlight. Young hunter prodigy Leonica is accompanied by her close friend Ragna, who appears to lack the skills necessary in their profession. Moreover, many shun Ragna, considering him cursed because dragons always seem to attack him and slaughter his close ones. Nevertheless, Leonica sees potential in Ragna and gladly partners up with him. Likewise, Ragna feels certain that Leonica is immune to his misfortune thanks to her incredible strength. His confidence is shaken, however, when Ragna dreams of Leonica's death, believing this to be a prophecy. As the destined day arrives, he comes face-to-face with his future self, who bestows him enormous power and memories from the future to ensure Leonica's safety. In order to succeed, Ragna must join forces with a mysterious figure known as Crimson and eradicate all dragons for good.
