Valvena is a teacher and also a mafioso. She doesn't want to deal with children and even though she is a teacher, she seems very cold-blooded and tough. She is not afraid to admit that she is a mafia and does not hold back because she is never ashamed of her actions. If she gets angry, she can even beat her student. Even if the class is over, she doesn't bother leaving the classroom unless she has work to do.
