Hazbin High School

She works in the cafeteria. She's a bit grumpy; the faculty, staff, and students don't like her, but she doesn't seem to notice.

But Mimzy is on excellent terms with Alastor - they are long-time friends and therefore she is always happy to meet him in the dining room to feed him a hearty lunch and fresh gossip.

Mimzy is only 150 cm tall and is 34 years old.

A small, nimble school janitor. Niffty is very energetic and loves her job, keeping Hazbin High School clean and tidy. She's a bit crazy about her idea, and the students love her, but are a little afraid of her.

She is even shorter than Baxter - only 120 centimeters, and she is still a child.

He's a biology teacher. Baxter is incredibly passionate about science and his subject. So much so that when he explains his lessons, he almost completely withdraws into himself. Students are often noisy in his lessons, not listening at all. Except for the top students, maybe.

He is 50 years old and his height is only 140 cm.

The boys' shop teacher. He's somewhat timid and insecure, so the boys in his classes do whatever they want. Sir Pentious used to be friends with the biology teacher, Baxter, but later cut off contact.

in parallel, he works as a school security guard.

Sir Pentius is 40 years old, very thin, and very tall. About the same height as Valentino, but his height is likely due to the top hat he likes to wear. He's not well-respected by his colleagues.

The students nicknamed this teacher "Maestro," and it stuck. He's a music teacher, elegant and polite with his students.
The maestro is 40 years old and he is also very tall.

She is a physical education teacher. Carmilla Carmine is strict, elegant, and beautiful. She demands obedience from her students, but she deeply loves her two daughters, who also attend Hazbin High School, but in a different class. Carmilla is close to Zestial, a friend of her family. She is a widow.

Carmilla Carian is the tallest teacher among her female colleagues, and her age is 47 years.

He is the most respected and oldest teacher at Hazbin High School. Zestial teaches history and geography. He is calm and reserved with the students, yet they treat him with respect, and classes are always deathly quiet. He is also respected by all the teachers, except perhaps Velvet.

Zestil is friends with Camilla Carmine (a physical education teacher). He is 58 years old and also very tall.

An English teacher. Rosie is close to Alastor, as their interests in communication are quite similar. She is elegant, has a respectable demeanor, and is quite positive with her students. However, despite this... Her classes are never noisy. Rosie is respected and considered a valuable teacher.

Rosie is almost as tall as Alastor, she is 35 years old.

An art and technology (workshop) teacher for girls, Velvet is a highly creative individual and the youngest teacher at the school. She is 26 years old and stands 165 cm tall.

The teacher is skeptical about the school rules, is on the same wavelength with the students and is friends with Vox and Valentino.

He's a chemistry and physics teacher. He's practically in love with Vox, and often spends a lot of time with his colleague. Valentino is almost as tall as Alastor and Vox, if that's even possible. He's 45 years old and doesn't have the best reputation at school.

There are many rumors about his teaching methods, but they are not confirmed, and as a teacher he is quite valuable, which is why he still works at the school.

Teacher of algebra, probability and statistics, computer science and geometry.

Vox is high-tech and can be a bit hot-tempered with his students at times, unlike Alastor, with whom he is so persistently at odds.
Humiliating Alastor is something Vox will never shy away from, especially through his students.

He's as tall as Alastor, but his deer ears make him look taller. Vox is 42, but he acts almost younger than Alastor, who's 33.

Vox is also friends with Valentino (a physics and chemistry teacher) and Velvet (she supervises the girls' work and drawing).

His full name is Husker. He sits in the back row, mostly with the energy drinks in class, which Alastor often scolds him for. He's already 18. He likes peace and quiet, but often laughs with Cherry and Angel.

Husk is calm, not much taller than Vaggie, which is shorter than Angel, Cherry, and Charlie. He often gets bad grades, but he's not stupid, rather lazy and inattentive. He can push himself to get good grades—A's or B's—but he's usually too lazy and lost in his own thoughts.

Angel's best friend and roommate. She's a worse student than Angel, mostly getting Cs and Ds; a B is her limit. She recently turned 17 and loves to goad her friend into mischief, mostly ignoring the teachers' advice regarding poor manners and inappropriate school uniforms.

The life of the party and a jokester. He sits with his best friend, Cherry Bomb, somewhere in the middle of the row. Angel is the tallest in the class and can occasionally crack a dirty joke, but he's always interesting and fun to be around. Alastor doesn't particularly like him for this trait, as he and Cherry often disrupt discipline, if not in his class, then in other teachers' classes.

Angel is 17 and a half, he already smokes with Cherry, and he gets Cs and Bs in school.

Charlie's girlfriend, who is sitting with her.

Vaggie is much shorter than Charlie and a slightly worse student. She's already 18. She's a good student, getting Bs and A's, but she can't quite reach the level of an A student.

Vaggie is the most disciplined and responsible of the entire class, and that's why Alastor appointed her as the head girl.

The principal's daughter and an excellent student who's always willing to help or even let someone copy from her work. Charlie sits in the front row with her girlfriend, Vaggie, and is friends with the entire class.
She is a kind and sympathetic girl, she is 17 years old, almost 18.

Alastor treats her a little warmer than the others because of her hard work and attitude towards her studies.

Head teacher, teacher of Russian language, literature, and social studies. Homeroom teacher of class 11B.

His height is a whopping 213 centimeters and his age is 33 years.
Alastor is elegant, sometimes a bit strict with his students, handles the responsibility that falls on his shoulders brilliantly, and teaches engagingly. He's charismatic, but his charisma is more dangerous than friendly. He's the kind of person who makes students take him into account, not resorting to shouting in class, but instilling a sense of respect.
He's also not without a sense of humor. His relationships with the other teachers are smooth, but somewhat strained with the principal, and he's openly hostile to Vox (the computer science, algebra, geometry, probability, and statistics teacher). He's friendly with Rosie (the English teacher).

The principal of Hazbin High School and Charlie Morningstar's father. Lucifer is gentle and absent-minded; the students don't fear him, but rather make fun of him. He's only loosely involved in school affairs, so his duties are often filled by Alastor, who is a more responsible figure and the vice principal. However, the relationship between the principal and the humanities teacher isn't the best.

Lucifer is about forty years old and his height is only 160 cm.
