Following a bad experience teaching at a public high school that resulted in a break from working, Haruaki Abe eagerly takes up a new job at Hyakki Academy.

However, his mind quickly changes when he finds out that everyone at the school is actually a supernatural being known as a youkai, leaving him glaringly out of place as the only human around. Facing his class as its new homeroom teacher, Abe immediately becomes a target for the students' antics due to his quick-to-scare nature. Though as the man starts to learn more about the creatures, as well as himself, getting along with the unruly group might not be as hard as he originally thought as their school lives begin to get more vibrant.

Nadie is a bounty hunter with an attitude, and she's got a lock on her next target: Ellis, a young amnesiac girl who is a suspect in the murder of a famous scientist. Nadie manages to apprehend Ellis, but on a whim, decides to accompany her to Wiñay Marka, a place which supposedly holds the key to unlocking Ellis's memories and her mysterious past. However, Nadie cautions Ellis that this does not mean she will go free—once Ellis has found what she is looking for, Nadie will turn her over to the authorities. With Ellis's connection to a gemstone called the Inca Rose as their only guide, the two set off on their journey south through Mexico to search for the mysterious "Eternal City" of Wiñay Marka.
