[DeepL Translation - needs review] Introduction to Volume 1: A beautiful new teacher, Ms. Kasai, arrives in a devastated classroom.
In fact, the previous homeroom teacher was hospitalized after attempting suicide due to bullying by a student.

However, the students did not yet know her true nature. ......
Kasai-sensei is a psychopath!
