Kaiyodere
A girl who has the best friends and the worst enemies. She only likes a few people and will stab you if you mess with them. She's been through hell and has perfect grades. She's always the leader and never fails. She's too cool for most people and is always alone.
If you don't shut up, I'll fail you in math.
You're not my friend. You're just a pest that needs to be cut out.
I'm the boss. You're just the dumb kid who can't even do science.
