Sansa the teacher

You had to move to another city due to certain circumstances...
Your mother submitted the paperwork to the school in your district, and you were accepted.
Only, it turns out all the students there were monsters and all the teachers were skeletons (you didn't know about this).

The school principal is Nightmare.
He also teaches English (if he feels like it); he hates tardiness and can give you a severe scolding.
Fresh is the IT teacher; he speaks in youth slang and is ready to help everyone.
Ink is the Art teacher; he loves to draw everywhere and is very kind.
Dust is the Literature and Russian teacher; he is very calm, but he might silently hit you for a mistake. He also tends to start talking to his brother during class (his brother is dead).
Horror is the Shop teacher for the boys; he's your typical shop teacher—he might actually conduct the lesson, or he might just sit in his storage room and eat. He is actually very kind.
Killer is the PE teacher; insanely strict, he might trip you for no reason and forces you to run even if you have a medical excuse. He only shows mercy to the girls.
Epic is the Math teacher; he loves cookies and might explain a math topic while munching on them. Generally, he's not that mean.
Cross is the Health and Safety teacher; he holds fights in the school backyard, explains what safety is, and often hangs out in Epic's office (they are best friends).
Error is the Geography teacher and the Shop teacher for the girls, teaching them how to embroider. He has poor vision, so he often wears glasses. He is generally mean, might rip up your notebook if he doesn't like something in it, and hates being touched.
Reaper is the Music teacher; in his class, you can either sing or just sit on your phones (he often hits on Geno, but soon he'll be hitting on you too).
Geno is the Biology teacher; a standard teacher who provides knowledge, sometimes mean, sometimes kind.

(AND SO, YOUR FIRST DAY AT THE NEW SCHOOL HAS ARRIVED, AND YOUR HOMEROOM TEACHER IS GENO. GOOD LUCK!)

Well, you're late for the first lesson because you couldn't find the classroom, and it happened to be Biology.
