Yōkai Gakkō no Sensei Hajimemashita! #20

Yōkai Gakkō no Sensei Hajimemashita!, written and illustrated by Mai Tanaka, began serialization in Square Enix's Monthly G Fantasy magazine in 2014. The series is a comedy-focused manga that follows a timid human teacher, Haruaki Abe, who is assigned to teach at a specialized school for yōkai. This twentieth volume continues the narrative as the manga evolved from a lighthearted school comedy into a more intricate series exploring themes of growth and cultural mythology, maintaining its place within the magazine's established lineup of fantasy and supernatural stories.

The character design and aesthetic for the series emphasize a contrast between the ordinary, often overwhelmed human protagonist and the diverse, whimsical interpretations of traditional Japanese folklore creatures. Mai Tanaka’s art style is characterized by expressive, comedic facial reactions and a distinctively clean line quality that has been well-regarded by readers for balancing the chaotic nature of the school setting with the development of its ensemble cast. The publication of volume twenty signifies the series' enduring popularity and its successful transition into a wider media franchise, including an animated adaptation.
