THE DOCTOR IS IN . . . OVER HIS HEAD

Kuro and Kotoko are a special doctor and nurse, helping goblins and spirits known as yokai. Their patients include an all-seeing eye, a tôfu boy, and a girl with two mouths. It’s a difficult yet fulfilling job, but some yokai disapprove of Kuro and Kotoko’s practice–and are dying to stop them!
