Teacher's Pet

Teacher's Pet is one of the many personas that appear in Yandere Simulator.

If an NPC with the Teacher's Pet persona sees you killing a student, they will remain shocked for a moment before running to their teacher and telling her a student attacked someone.

The teacher will respond with, "Dead? Lead me to them!" and whichever student told her will lead her to where they saw the body. If Yandere-Chan moves the corpse before they arrive, the teacher will think it is a prank and scold their student. However, if Yandere-Chan leaves the body there, the teacher will call the police and guard the student's corpse.

If a Teacher’s Pet witnesses a murder/corpse but someone else is already reporting it, then the student will run and hide in a classroom as if they had the Coward persona, instead of informing a teacher.

The student that witnessed the murder will be mentally scarred, leaving their pupils small as if they were shocked. In Yandere-Dev's "How To Get Away With Murder In Yandere Simulator" video, he suggested that teacher's pets, alonside the rest of the personas, will interact differently around Yandere-chan after discovering her gruesome secret.

Like how all of the female students in the game as of the current update (except from the incomplete AIs and Phantom Girl) have the "Coward" persona, all the male students, with the exception of Senpai, have the "Teacher's Pet" persona.

Trivia

 * At the moment, the only students with the teacher's pet persona are male students.
 * Senpai is the only boy without a teacher's pet persona.
 * Since NPC's don't repond to blood yet, you can easily drag a body out of the way so the teachers will think the murder was a prank.
