Hereditary Evil Raiser Syndrome is connected to Multiple Personality Disorder. The name of the HER personality is a cat named Abyss and her first host was Elluka Clockworker, that was in Blood-Stained Switch. The doctor that split them up was Adam Moonlit. That freed Abyss to move from host to host, controlling them, whispering to them, telling them what to do. When a person is controlled by Abyss there eyes turn red and there blood turns people.
