Plot
Haruaki Abe is not the bravest person in the world. In fact, he's so cowardly, grade school children push him around, which has really made it hard for him to do his dream job: being a teacher. But luckily, a family friend hooks him up with a job teaching at Hyaaki Academy. But it's going to be way more than Haruaki expects it to be when he finds out on his first day that this is no ordinary school. It's a high school for yokai, filled with students and teachers who are all sorts of terrifying. It's going to take a will of steel to work here, but fortunately, Haruaki has a secret up his sleeve to help him out as he's pushed to his limits everyday teaching (and surviving) his yokai students.

Characters
Haruaki is the main protagonist of A Terrified Teacher at Ghoul School! He is a cowardly person with impossibly bad luck. He has a deep love and appreciation for sailor uniforms. He is often called Seimei by his students after the ancient Abe no Seimei. The Principal is a mysterious man, and is the one who initially found Haruaki the job at Hyaaki Academy. He seems to know something about Haruaki that no one else does. Mikoto Sano is a deuteragonist and is in Haruaki's class. He is a Yakubyougami. While aloof, he's quick to anger and does not hesitate when it comes to throwing hands, often being the biggest thorn in Haruaki's side. Sano is constantly beating up and calling Haruaki names. He does have a soft spot for his best friend, Mamekichi Maizuka, and for small animals. Mamekichi Maizuka is a Tanuki yokai and best friends with Mikoto Sano. He has a childlike demeanor and spends a lot of time with Sano and their other friends, Hijita and Zashiki. He's nicer to Haruaki than Sano is, but he doesn't really respect the guy either. He coined the nickname Seimei. Kotarou Hijita is a dorotobou yokai who is good friends with Sano, and Mamekichi. His best friend is the Zashiki-Warashi, Beniko Zashiki, who he's known since he was a child. He likes to pull practical jokes, particularly on his teacher, and tries to come off as a super cool dude (but he still has a girly side to him, as he also like Shoujo manga). He also seems to have a bit of a sister complex, but he denies it wholeheartedly. Beniko Zashiki is a Zashiki yokai, as her namesake says. She has a very aloof personality, and cares very little about real things, but has a deep dedication to video games and will hole up in her room to play them. Though she can be very aggressive, she does have a soft side for her friends, but it is only seen on very rare occasions. Izuna Hatanaka is a teacher at Hyaaki Academy alongside Haruaki, one of few teachers who do not fear him. He is a kamaitachi, which is a weasel yokai with sickles for arms. He is very serious, with a no non-sense personality. He does care deeply for those close to him, always thinking about his friends, and his lovely wife and kids. Rintarou Miki is another teacher and co-worker of Haruaki's, and he is an oni yokai. He was the first teacher to introduce himself to Haruaki, being among the few teachers who is not scared of Haruaki. He is normally calm and quippy, but whenever he gets drunk, he goes wild, destroying things and being very loopy. There is a darker side to him, though, and not many people know about it.
