Meet Kantarou, a folklore scholar living in the Taisho period. Ever since he was a child, he has been able to see and talk to various spirits. But now that Kantarou's all grown up, he moonlights as an exorcist solving the problems of ghosts and demons... with the help of Haruka, the legendary demon-eating tengu!

Haruka fails at eating a demon boy - even though that's his purpose in life. In confusion, Haruka questions his relationship with Kantarou. Haruka and Kantarou are befriended by a priest in need of assistance. Can the priest can make Haruka see the light in his dark past?

Kantarou is sent to a village to ensure the safe execution of its annual fortune-telling festival. Run by a family of women who have had all the men in their lives meet with strange and eerie misfortunes, the festival seems cursed. Will Kantarou and Haruko break the curse before they become its first out-of-town victims?

Kantarou and company are duped into exterminating youkai for a woman who turns out to be a key player in a big smuggling ring! Although they manage to escape, the main woman is still at large... and affiliated with Raikou, a fellow youkai exterminator - who is determined to kill the legendary Demon-Eating Tengu!

Kantarou's struggle against the mysterious Raikou Minamoto and his strange band continues as the even more mysterious Father Edwards returns to the fray! Facing off against possessed actresses and demons from the great beyond, Haruka and Kantarou are up to their necks in trouble, especially when Minamoto's true motives are finally revealed...

Three stories, three sundry adventures! First, there's the day in the life of Watanabe as he serves Minamoto in his estate. Then there's Kantatou stealing himself to finally ask Haruka about his past... but getting so distracted by the many familiar faces he runs into that he forgets what it was he was going to ask! And finally, a lazy kid runs away from his mountain home to accompany Sugino on his search for the lost Muu-chan.

Kantarou takes on a case of finding a missing person that leads him to an ironworking village affiliated with a mysterious organization called the Toratsugumi Society - a group that is reviving the dead...

The last part of the Chimera arc comes to a close as Kantarou and Haruka battle Minamoto and Sakata.
