Personas

It's been confirmed by the creator of Yandere Simulator there will be more personalities.

Coward: Would try to avoid you or run away from you if they see you committing murder, they'll run out of school grounds to call the police.

Justice Minded: Might try to stalk you, and try to catch you in the act of committing murder so they can report you and get you arrested.Not in game yet.

Social Butterfly: Spreads rumors about you committing murder to let them know what kind of person you really are. This damages your reputation for every day she's alive. This persona is already in the game but is just a null value and its unused.

Fragile: Becomes terrified of you, starts begging you to spare their life in exchange for their silence. Not in game yet.

Evil: Congratulates you on your kill, promises not to say a word about it to anyone.Not in game yet.

Teacher's Pet: Runs to the nearest teacher and tells about the murder
 * If a student with the Teacher’s Pet personality discovers a corpse or witnesses murder, they will run and tell a teacher.
 * If a teacher is informed of a murder, they will run to the scene of the crime and investigate it.
 * If a Teacher’s Pet witnesses a murder/corpse, but someone else is already reporting a murder/corpse, then the student will run and hide in a classroom instead of informing a teacher.
 * If a Teacher’s Pet informs a teacher of a murder/corpse and leads the teacher to the scene of the crime, but Yandere-chan has already cleaned up the evidence, the teacher will conclude that the student was pulling a prank on her.
 * If a Teacher's Pet witnesses a murder and leads the teacher to the scene of the crime, but Yandere-chan has moved the corpse far away enough that the teacher cannot see it, the teacher will conclude that the student was pulling a prank on her. That means even if Yandere-chan did not mop the blood, dump the weapon and blood-stained uniform and the corpse into the incinerator, the teacher still would not call the police.
