When a Spiteful student witnesses Ayano Aishi commit murder, they will approve of the kill if the victim was bullying them or is a student with a low reputation. But if they witness the murder or corpse of a regular student, they will flee the school and call the police.
If Ayano murders someone they dislike, then Ayano will not receive any reputation penalty from them. If she murders anyone else, they will damage her reputation every day they are left alive.
If Ayano tries to take a picture of them, they will become annoyed and hide their face. If she is in the Photography Club, they will stand still.
- This persona was implemented in the March 6th, 2018 Build.
- In the future, Spiteful students may have someone they dislike from the beginning of the game.
- Spiteful student will also have an ability to immune to intimidation if Ayano joins the delinquents in the future builds (Currently, this feature isn't implemented yet). 
- Previously, students with the Spiteful persona had the Evil persona instead.
- Currently, the only student to have the Spiteful persona is Borupen Saishiki.
